3 Changes between versions 0.4b34 and 0.4b35 (released ??????????????)
4 ====================================================================
6 1. Added a note in the dump man page saying that the default
7 blocksize can be 32 if -d is used with a high density argument.
8 Thanks to Antonios Christofides <A.Christofides@itia.ntua.gr>
11 2. Fixed configure to correctly understand CPPFLAGS, CFLAGS,
12 LDFLAGS environment variables. Thanks to Arcady Genkin
13 <antipode@users.sourceforge.net> for reporting the bug.
15 3. Make -e/-E options of dump accept an unlimited number of inodes
16 to be excluded, rather than a hardcoded maximum. Thanks to
17 Dietrich Rothe <d-rothe@users.sourceforge.net> for the patch.
19 Changes between versions 0.4b33 and 0.4b34 (released April 18, 2003)
20 ====================================================================
22 1. Fixed the INSTALL file to reflect the actual install paths.
23 Thanks to David Ronis <ronis@ronispc.chem.mcgill.ca> for
26 2. Fixed the configure script to only check for headers presence
27 instead of trying to compile them. This should fix issues
28 with old build environments. Thanks to Kari Lempiainen
29 <kari@funky.pp.fi> for reporting the bug.
31 3. Fixed restore to correctly ignore sockets when comparing
32 a dump (as socket cannot be properly restored anyway). Thanks
33 to Gunther Reiszig <gunther@mit.edu> for reporting the bug.
35 4. Fixed restore to correctly access the archive file (-A argument)
36 even when using a remote tape. Thanks to Fabrice Bellet
37 <fabrice@bellet.info> for reporting the bug.
39 5. Fixed (again) handling of long (largefile) seeks in rmt.
40 Thanks to Fabrice Bellet <fabrice@bellet.info> for reporting
43 6. Fixed restore corner case when dealing with large block sizes
44 dump is able to write now (-b 1024). Thanks to Fabrice Bellet
45 <fabrice@bellet.info> for reporting the bug.
47 7. Fixed a bug preventing dump to access a filesystem having
48 a label exactly 16 bytes in length. Thanks to <minduni@ti-edu.ch>
49 for reporting the bug.
51 8. Made dump store dump dates using explicit timezones, fixing a
52 problem with incremental dumps if the timezone is modified
53 between the dumps. Thanks to Philippe Troin <phil@fifi.org> for
54 the bug report and the patch.
56 9. Fixed a bug encountered when dumping individual files (not full
57 filesystems or directories) and dangling symbolic links happen
58 to be in the list of files. For as far as dump is concerned,
59 dangling symbolic links are allowed, and are dumped as is.
60 Thanks to Jin-su Ahn <jsahn@ee.snu.ac.kr> for reporting the
61 bug and providing the fix.
63 10. Fixed open and creation modes and permissions for QFA and
64 table-of-contents files in dump and restore. Thanks to
65 Philippe Troin <phil@fifi.org> for the patch.
67 11. Fixed the archive file descriptor handling enabling it to be 0.
68 This can happen in some cases when shell redirections are used.
69 Thanks to Philippe Troin <phil@fifi.org> for the patch.
71 12. Delayed the opening of archive file until after suid had been
72 dropped (fixing a possible security issue if dump is suid).
73 Thanks to Philippe Troin <phil@fifi.org> for the patch.
75 13. Fixed the 'S' command handling in the rmt client part.
76 Thanks to Philippe Troin <phil@fifi.org> for the patch.
78 14. Modified the end-of-tape script handling to print out statistics
79 (and stop the timer) before launching the eot script. Also, the eot
80 script does not get run anymore when using -M (which makes sense) or
81 when multiple tapes are listed on the command line
82 (-f tape0,tape1,tapen) (which also makes sense).
83 Thanks to Philippe Troin <phil@fifi.org> for the patch.
85 15. Relicensed dump/restore under the 'revised' BSD license, as per
86 ftp://ftp.cs.berkeley.edu/ucb/4bsd/README.Impt.License.Change.
88 16. Added LZO compression to dump. This new compression method has
89 the advantage of being super fast, thus not killing tape streaming
90 on slow machines. Thanks to Helmut Jarausch
91 <jarausch@igpm.rwth-aachen.de> for the patch and to
92 Markus Oberhumer <markus@oberhumer.com> for giving special permission
93 to include his miniLZO project (GPL licensed) in dump/restore.
95 17. Some small buffer overruns fixes in rmt. Thanks to Antonomasia
96 <ant@notatla.demon.co.uk> for reporting the bugs.
98 18. Added a special rmt version which can do encryption when writing
99 to tape. Read examples/encrypted_rmt/README for details on
100 how to enable and configure it. Thanks to Ken Lalonde
101 <ken@globalremit.com> for the patch.
103 19. Made dump work with 2.5 kernel end of tape early warning semantics.
104 Thanks to Kai Makisara <Kai.Makisara@kolumbus.fi> for the patch.
106 20. Fixed a bug which caused dump -w|-W not to work anymore, because
107 the fs_freq and fs_passno fields in /etc/mtab are always set
108 to 0 0. Thanks to Trent Piepho <xyzzy@speakeasy.org> for
111 Changes between versions 0.4b32 and 0.4b33 (released February 10, 2003)
112 =======================================================================
114 1. Added a note in the restore man page clarifying the question
115 'set the permissions on the current directory ?' asked by
116 restore at the end of treatment in -i and -x modes.
118 2. Fixed the endianess issues when reading compressed tapes.
119 Thanks to Dark Force <daq4th@users.sourceforge.net> for
120 reporting this bug and providing test cases.
122 3. Fixed the "ACL won't be dumped" warning message (which showed
123 an extra, unrelated error message). Thanks to Dragan Krnic
124 <dkrnic@lycos.com> for reporting this bug.
126 4. Made dump look first into /etc/mtab, then into /etc/fstab
127 when searching for filesystem paths. Also fixed some problems
128 caused by binding mounts or multiple block device mounts.
129 Thanks to Matus Uhlar <uhlar@fantomas.sk>, Elliott Mitchell
130 <ehem@m5p.com>, Greg Edwards <gedwards@users.sourceforge.net>,
131 Brian Hoy <brian.hoy@opus.co.nz>. (fixes Debian bugs #147086
132 and #160305, Sourceforge bugs #618699 and #679832).
134 5. Made dump's -I option accept the value '0' meaning all the
135 read errors will be ignored. This can be useful when running
136 dump from unattended sessions (like cron jobs). Thanks to
137 John I Wang <jiwang@users.sourceforge.net> for the suggestion.
139 6. Fixed the output of dump to indicate 'blocks' instead of
140 'tape blocks' in the various messages (blocks are always
141 1 Kilobyte, tape blocks are 1 BK * '-b' argument), and
142 made it clearly print the current blocksize at the start of
143 a dump. Thanks to Michal Szymanski <msz@astrouw.edu.pl> for
146 7. Made rmt understand long (largefiles) seeks.
148 8. Fixed build with very old versions of libext2fs, where
149 EXT2_FT_* constants were undefined.
151 9. Made dump accept the dumpdates path on the command line
152 (-D file option) instead of using only the hardcoded one.
153 Thanks to Piete Brooks <pb22@users.sourceforge.net> for the
156 10. Enabled rmt, LFS, readline, QFA options by default in
157 ./configure. Updated the configure process (new versions
158 of config.guess, config.sub etc).
160 Changes between versions 0.4b31 and 0.4b32 (released November 15, 2002)
161 =======================================================================
163 1. Changed dump to use fcntl(F_SETLK) style locking instead
164 of flock() when locking the dumpdates file. With the old
165 locking scheme, a local user having read rights on the
166 dumpdates file could be able to do a Denial of Service attack
167 on dump. In order to lock the dumpdates file with the new
168 scheme, the user would need to have write access on the file.
169 Thanks to Richard Johnson <Richard.Johnson3@ey.com> for
170 reporting the bug (originally a bugtraq post).
172 2. Fixed interactive 'ls' which caused spurious errors warnings
173 about 'undefined filetypes' detected. Thanks to Jorgen Ostling
174 <jorgen_ostling@users.sourceforge.net> for reporting this
177 3. Fixed dump's estimate when dealing with sparse inodes.
179 4. Modified dump to allow setting a blocksize bigger than 32kB
180 (raised the limit to 1024kB), because newer hardware needs
181 this for proper operation. Thanks to Dirk Traenapp
182 <dtraenapp@users.sourceforge.net> for reporting this.
184 5. Fixed a bug causing Dump to stop and report an error if an
185 inode number in the exclude file was followed by some amount
186 of whitespace. Thanks to Jeffrey Sofferin
187 <sofferin@users.sourceforge.net> for reporting this bug.
189 6. Fixed a bug which caused restore, in some particular cases,
190 to ask some 'scary' questions and leave a bunch of RSTTMP
191 directories behind when restoring incremental tapes. Thanks
192 to Philippe Troin <phil@fifi.org> for reporting this bug and
193 providing the test cases.
195 7. Changed the wording when inodes are excluded from dump:
196 replaced 'Added inode 7 to exclude list' with
197 'Excluding inode 7 (resize inode) from dump', as suggested
198 by Elliott Mitchell <ehem@m5p.com> in a Debian bug report.
200 Changes between versions 0.4b30 and 0.4b31 (released July 30, 2002)
201 ===================================================================
203 1. Fixed rmt open flags transmission (GNU's symbolic syntax over
204 rmt) which I broke in 0.4b29. Thanks to Eros Albertazzi
205 <eros@lamel.bo.cnr.it> for reporting the bug.
207 Changes between versions 0.4b29 and 0.4b30 (released July 25, 2002)
208 ===================================================================
210 1. Made dump print out the ext2 logical block number in case of a read
211 error, which can be given as an argument to debugfs' ncheck command,
212 in order to find out the affected inode. Added note about this
213 usage in dump's man page.
215 2. Fixed a problem in restore when reading tapes written on big
216 endian machines with very old versions of dump. The patch was
217 contributed by George Helffrich <george@geology.bristol.ac.uk>.
219 3. Fixed the tape length calculation when using large tapes
220 and compression. Thanks to Georg Lippold
221 <g_lippold@sourceforge.net> for reporting the bug.
223 4. Added a new set of examples in dump_on_cd_2 directory, based
224 on dump_on_cd examples but somewhat enhanced, supporting DVD
225 media, and localized in english and german. Thanks to
226 Georg Lippold <g_lippold@sourceforge.net> for the new scripts.
228 5. Made dump save 32 bit UID/GID. Internally, this was achieved
229 by switching from the old BSD inode format to the new BSD
230 inode format, which means that the tape format was changed.
231 However, since all restore versions out there should
232 transparently support both inode formats, the change should
233 have no side effects. Thanks to John Yu <jky@cs.bu.edu> for
236 6. Fixed a lot of warnings in the code shown when compiling
237 with 'gcc -W'. Thanks to Matthias Andree
238 <matthias.andree@stud.uni-dortmund.de> for reporting this.
240 7. Fixed a small markup bug in the dump man page. Thanks to
241 Eric S. Raymond <esr@minx.thyrsus.com> for submitting the
244 8. Rewrote entirely the man pages using the tmac.an macro
245 package (Linux man page format) instead of the original BSD
246 format. They should be now cleaner and easier to modify.
248 Changes between versions 0.4b28 and 0.4b29 (released June 8, 2002)
249 ==================================================================
251 1. Fixed a problem in the rmt ioctl command, where ioctl's issued from
252 non Linux clients were misinterpreted. The description of the problem
253 (incompatible numbering in Linux mtio opcodes) is documented at
254 ftp://ftp.fokus.gmd.de/pub/unix/star/README.mtio . Thanks to
255 Jörg Schilling <schilling@fokus.gmd.de> for reporting this bug and
256 providing an excellent, cross-platform replacement for rmt in his
259 2. Fixed a bug reported by Andy Mentges <amentges@jumpline.com>
260 which caused restore to fail when the inode maps were not entirely
261 contained on the first volume (when using really small volumes or
262 when dumping a huge number of inodes).
264 3. Fixed a problem in dump, where files in subdirectories of directories
265 that have the nodump flag set (or being excluded with -e/-E) were
266 sometimes incorrectly dumped (instead of being excluded). The original
267 fix is from David C Lawrence <tale@dd.org> in the FreeBSD version
268 of dump: http://www.FreeBSD.org/cgi/query-pr.cgi?pr=32414
269 Thanks to Ted Grzesik <tedgyz@roostme.com> for reporting the bug and
270 help testing the patch.
272 4. Added some example scripts from Gerd Bavendiek <bav@epost.de>
273 which makes one able to pipe the output of dump, by the net, to
274 a remote CD-burner server.
276 5. Made dump use O_CREAT|O_TRUNC both locally and remotely (over rmt),
277 and use GNU's symbolic syntax over rmt instead of numerical values
278 to assure multiple platform compatibility.
280 6. Documented the -d option in restore.
282 7. Added a -v (verbose) mode to dump. For now it just prints the number
283 of the inode being dumped, but this could evolve in future versions
284 to include interesting debugging output.
286 8. Added a -o flag to restore, which automatically restores the current
287 directory permissions in -i or -x mode, without asking the operator
288 whether to do so. Patch submitted by Tony Clayton <tonyc@e-smith.com>
289 and Peter Samuel <peters@e-smith.com>.
291 Changes between versions 0.4b27 and 0.4b28 (released April 12, 2002)
292 ====================================================================
294 1. Fixed a bug in the QFA feature which could have caused
295 a bad tape positionning on restore (causing extra delays in
296 restore). Credits go to Uwe Gohlke <uwe@ugsoft.de>.
298 2. Added a small note in the dump man page specifying that
299 there should be no white space between the option letter and
300 the -j or -z parameter, thanks to Kenneth Porter <shiva@well.com>
302 3. Made restore work with older versions of the readline library,
303 by checking in configure for several extended symbols. Restore
304 can now be compiled with a readline as old as the 2.0 release
305 (though it may be a good idea to upgrade it to a more recent
306 version...). Thanks to Andrew Donkin <ard@waikato.ac.nz> for
307 reporting the build failures.
309 4. Fixed a performance problem with the QFA file creation in
310 dump, which made unnecessary seeks on the tape slowing down
311 the dump. Thanks to Andrew Donkin <ard@waikato.ac.nz> for
312 reporting this issue.
314 5. Removed the inclusion of some kernel headers in the dump
315 source, which prevented the compile in some kernel/glibc
316 headers/architecture combination. Thanks to Bdale Garbee
317 <bdale@gag.com> for reporting the bug.
319 6. Added the appropriate error message when dump fails to
320 open the output file for writing. Thanks to Amith Varghese
321 <amithv@yahoo.com> for reporting this bug.
323 7. Made restore able to understand large Solaris ufsdump tapes
324 (containing inodes bigger than 4194304). Sun have introduced
325 an "extension" to the dump tape format when dealing with
326 those inodes, which was uncorrectly handled by Linux restore.
327 Thanks to Uwe Gohlke <uwe@ugsoft.de> for reporting the bug and
328 providing a test case.
330 8. Added the -m parameter to dump which optimises the output for
331 inodes having been changed but not modified since the last dump
332 ('changed' and 'modified' have the meaning defined in stat(2)).
333 For those inodes, dump will save only the metadata, instead of
334 saving the entire inode contents. Inodes which are either
335 directories or have been modified since the last dump are saved
336 in a regular way. Uses of this flag must be consistent, meaning
337 that either every dump in an incremental dump set have the flag,
340 Changes between versions 0.4b26 and 0.4b27 (released February 15, 2002)
341 =======================================================================
343 1. Fixed behaviour of dump when exceeding resource limits
346 2. Added the -L flag to restore to allow the user to specify a
347 maximal allowed number of miscompares when using restore
348 with the -C option to check the backup.
350 3. Detailed the manual entry for the -N option of restore.
352 4. Added the -a flag to restore to make able doing unattended
353 restores in -i or -x mode (automatically walks through the
354 multiple dump volumes).
356 5. Extended the QFA mode to work with local files and/or
357 remote tapes and files. This way, restore can know in advance
358 the tape number and the offset for the inodes to extract and
359 can minimize the extraction time by seeking directly to the
362 6. Added the -A <archive> option to both dump and restore,
363 which makes dump to archive a dump table-of-contents in
364 the specified file to be used by restore to determine
365 whether a file is in the dump file that is being restored.
366 (the archive file syntax is also compatible with the
367 Solaris ufsdump generated one).
369 7. Small fix in restore making it able to read some (broken ?)
370 Solaris ufsdump tapes.
372 8. Fixed dump to correctly recognise the root filesystem when using
373 ext2 disk labels (LABEL=/). Thanks to John Yu <jky@it.bu.edu>
374 for reporting this bug.
376 9. Added the -P <file> option to restore to create a
377 Quick File Access file from an already made dump. Patch
378 contributed by Uwe Gohlke <uwe@ugsoft.de>.
380 10. Made restore compile and run on Solaris, making it a
381 possible replacement for the standard ufsrestore. Port was
382 contributed by Uwe Gohlke <uwe@ugsoft.de>.
384 Changes between versions 0.4b25 and 0.4b26 (released January 7, 2002)
385 =====================================================================
387 1. Added a set of backup scripts from Eugenio Diaz
388 <getnito@yahoo.com> in the examples section. It features
389 automatic (cron based) full and incremental dumping of
390 several filesystems on a separate filesystem.
392 2. Fixed a off-by-one miscalculation which disabled dumping
393 a one letter subdirectory. Thanks to Chris Siebenmann
394 <cks@utcc.utoronto.ca> for reporting the bug.
396 3. Fixed several restore bugs occuring when trying to
397 restore some missing files on the tape. Thanks to Chris
398 Siebenmann <cks@utcc.utoronto.ca> for reporting the bug.
400 4. Fixed --with-ldopts configure argument passing, installing from
401 a separate object directory, makefile cleanups contributed
402 by <splite@purdue.edu>.
404 5. Fix a bug which could caused, in some conditions, the highest
405 number inode of a filesystem, to not be dumped. Many thanks
406 to Chris Siebenmann <cks@utcc.utoronto.ca> for helping me
409 Changes between versions 0.4b24 and 0.4b25 (released November 17, 2001)
410 =======================================================================
412 1. Added a mini howto from Patrick Walsh in the examples
415 2. Minor man pages syntax corrections. Thanks to
416 Chris Danis <screechco@home.com> for reporting the bugs.
418 3. Added a script from David B. Peterson <dave@toppledwagon.com>
419 to the examples section. It features dumping several
420 filesystems to a remote tape drive upon ssh.
422 4. Added a patch provided by Richard Jones <rich@annexia.org>
423 which allows BRADEMAX (number of read errors tolerated by
424 dump) to be adjusted using the -I option.
426 5. Fixed a bug which disabled doing "restore -C -f -". Thanks
427 to Clemens Stiglechner <a9401816@unet.univie.ac.at> for the
430 6. Add the -l option to restore to specify if, when doing a
431 remote restore, the file used to access the backup is a
432 regular file (the defaults being a tape drive). Restore needs
433 to know this information when reading a remote compressed
434 dump. Previously, this information was autodetected, but
435 the autodetection code fails (with ioctl: Inappropriate ioctl
436 for device) when using a non Linux remote box. Thanks to
437 many users and especially to Eros Albertazzi
438 <eros@lamel.bo.cnr.it> for reporting this.
440 7. Found a workaroung for the dump deadlock problem (3 childs
441 stuck in pause(), father in read()). The workaround seems
442 to work for me and several beta-testers. If it doesn't work
443 for you, please report back.
445 8. Updated the RPM spec file (BuildPrereq, URL etc).
447 Changes between versions 0.4b23 and 0.4b24 (released September 12, 2001)
448 ========================================================================
450 1. Fixed the permissions of a newly created QFA file by dump.
452 2. Cleaned up the source of dump (the external variables
453 definition was a complete mess, making possible to have
456 3. Fixed restore to use the full tape volume path when doing
457 a compare (since it changes the working directory to the
458 filesystem being compared in the process).
460 4. Added the -q option to dump which makes dump abort
461 whenever it needs operator attention. It should be
462 easier to use dump in scripts with this option.
464 5. Detect the use of incompatible options to dump and
465 refuse them (like -a and -B options together).
467 6. Added bzip2 compression to dump/restore (use option -j level
468 to select it). Note that you will need a restore version
469 >= 0.4b24 in order to restore a bzip2 compressed dump.
470 The same warning as for the zlib compression applies:
471 the tape format of a bzip2 dump is not compatible with the
472 original BSD tape format.
474 7. Fixed a overflow problem in dump corrupting the dump when
475 very large files were encountered. Thanks to Vladimir Nadvornik
478 8. Added a ioctl(BLKFLSBUF) in dump which should flush the
479 kernel buffer/page cache before starting the dump, helping
480 a bit those who use dump on mounted filesystems. Thanks to
481 John Yu <jky@it.bu.edu> and to Theodore T'so <tytso@mit.edu>
484 9. Updated the RPM spec file following the RedHat changes
485 (dynamically linked binaries now in /usr/sbin etc).
487 10. Added a patch from Helmut Jarausch <jarausch@igpm.rwth-aachen.de>
488 which enables restore to recognise multi volume compressed dumps
489 done on CD. Included his scripts for dump (which pipe the dump
490 output directly into cdrecord) and restore. There is now
491 possible to to backups to CD on the fly!
493 Changes between versions 0.4b22 and 0.4b23 (released July 20, 2001)
494 ===================================================================
496 1. Fixed a buffer overflow in restore/tape.c. Patch provided by
497 Marcus Meissner (Caldera International Security Dept.).
499 2. Implement the Sun rmt extended protocol. Patch submitted
500 by Ian Gordon <iangordon@users.sourceforge.net>.
502 3. Check for the e2fsprogs header <ext2fs/ext2_fs.h> instead of
503 the linux kernel header. This ensures that dump always has the
504 latest version of this file. Patch submitted by
505 Andreas Dilger <adilger@turbolinux.com>.
507 4. Report any filesystem present in either /etc/fstab with a
508 positive passno or /etc/dumpdates in dump -w output.
509 Patch submitted by Andreas Dilger <adilger@turbolinux.com>.
511 5. Fixed the looping problem in dump introduced in the
514 6. Changed the -B option of dump to limit the size of
515 _compressed_ output per volume if compression is on.
516 Patch contributed by Helmut Jarausch
517 <jarausch@igpm.rwth-aachen.de>. Note however that, since
518 it is impossible to predict the size of the compressed
519 data before doing the compression, the -B limit is a bit
522 7. Fixed a bug in reading the operator typed file/tape path for
523 the next volume in restore.
525 8. Implemented a "-F script" option to restore which permits the
526 user to specify a script which will be launched at the
527 beginning of each tape, useful for automatic programming of
528 tape changers for example. See the restore man page for the
529 script parameters and return codes.
531 9. Small fix for the QFA routines provided by Uwe Gohlke
532 <uwe@ugsoft.de>, and some recommendations for QFA uses in
535 10. Fixed the multivolume restoring where making a mistake
536 to the 'Mount next tape' prompt caused several blocks to
539 11. Enhanced the -e option of dump to take as a parameter a
540 comma separated list of inode numbers.
542 12. Added the -E option to dump which specify a file containing
543 inode numbers to exclude from the dump.
545 13. Fixed the compressed multi-volume dump + restore.
547 Changes between versions 0.4b21 and 0.4b22 (released May 12, 2001)
548 ==================================================================
550 1. Made dump report the number of blocks dumped per volume.
551 Thanks to Kenneth Porter <shiva@well.com> for the suggestion.
553 2. Fix a bug in dump where waiting too much at the 'change volumes'
554 question caused the volume to be rewritten. Thanks to
555 Graham Reed <greed@users.sourceforge.net> for reporting the
556 bug and providing a patch.
558 3. Added a compression option to dump, contributed by Jerry
559 Peters <gapeters@worldnet.att.net>.
561 WARNING: the compression works only on files/pipes and
562 drives supporting variable block size.
564 WARNING2: tapes created using the compression feature are
565 incompatible with the standard dump tape format, and a
566 version of restore >= 0.4b22 will be needed for extraction.
568 4. Fixed some compilation problems for glibc 2.2.2 and 64 bit
569 architectures. Thanks to Paul Slootman <paul@debian.org> for
570 the patch and to Bdale Garbee <bdale@gag.com> for forwarding
573 5. Many cleanups (CPP defines, const char warnings, check of
574 ext2fs COMPAT flags, time_t cleanups, added libext2 version
575 in dump usage text) by Andreas Dilger <adilger@turbolinux.com>.
577 6. Made --prefix option work in configure. All the install path
578 are now based on the configure parameters.
580 7. Added the Quick File Access mode in dump/restore, contributed
581 by Uwe Gohlke <uwe@ugsoft.de>. In this mode, dump stores in
582 a file tape position for each inode, and this file is used by
583 restore (if called with parameter Q and the filename)
584 to directly position the tape at the file restore is currently
585 working on. This saves hours when restoring single files from
586 large backups, saves the tapes and the drive's head. Use
587 --enable-qfa option of configure to compile in the QFA support.
589 8. Added the possibility to dump several files and directories
590 in a single invocation of dump. Thanks to Uwe Gohlke
591 <uwe@ugsoft.de> for implementing this option.
593 9. Fixed the dumping and restoring of files with holes
594 (files ending with holes didn't get dumped or restored
597 10. Fixed a socket descriptor leak in dump, which leaved opened
598 3 file descriptors per dump process (and there is one dump
601 11. Fixed dump large file system support, by explicit use of
602 open64/lseek64/etc functions (explicit use needed because
603 e2fsprogs libraries don't behave well when compiled with
604 FILE_OFFSET_BITS=64).
606 Changes between versions 0.4b20 and 0.4b21 (released January 13, 2001)
607 ======================================================================
609 1. Fixed some bugs in the dump -w|-W logic introduced by
610 the previous version. Thanks to Andreas Dilger
611 <adilger@turbolinux.com> for his help on this one.
613 2. Fixed again a compilation problem when using old e2fs
614 headers (filesystem label related). Thanks to many users
615 who reported this stupid error.
617 3. Fixed a build problem on old lib5 based systems dealing with
618 _PATH_MNTTAB being undefined. Thanks to John Adams
619 <johna@onevista.com> for reporting the bug.
621 4. Improved the error detection in restore when creating
622 the temporary files in TMPDIR. Now restore will corectly
623 report a 'no space left on device' error instead of
624 strange errors which could imply an archive corruption.
625 Thanks to Gabriel Somlo <somlo@cs.colostate.edu> and
626 bgjenero <bgjenero@sympatico.ca> for reporting the bug.
628 5. Added the throughput information in dump's progression
629 messages. Thanks to Andreas Dilger <adilger@turbolinux.com>
632 6. Use libext2fs's inode scanning routines, which are particularly
633 robust when dealing with errors (especially when having some
634 bad blocks on the filesystem). Many thanks to Colin
635 <colin@horizon.com> for reporting the bug, investigating
636 the issues, finding a workaround, writing the patch and
637 fully testing it... (of course, if this patch will break
638 anything, he is to blame for :-)).
640 7. Made dump and restore LFS aware. Dump can dump a filesystem
641 containing large files, generate a large file on output and
642 restore can restore them. This feature is not enabled by
643 default, use --enable-largefile option of configure to enable
644 it (you need to have a LFS aware glibc though). Thanks to
645 Andrea Arcangeli <andrea@suse.de> for submitting the patch,
646 and to Theodore T'so <tytso@valinux.com> for his always
649 8. Made dump ask upon a tape write error if it should rewrite
650 the current volume (assume this is a bad tape) or if it should
651 assume an end-of-tape condition (useful for tape drives which
652 behaves badly at the end of the tape). Thanks to Andreas
653 Dilger <adilger@turbolinux.com> for the suggestion.
655 Changes between versions 0.4b19 and 0.4b20 (released November 10, 2000)
656 =======================================================================
658 1. Fixed a small compilation problem due to a change
659 in the definintion of the struct sigaction in
660 glibc 2.0 / libc5. Thanks to Gunther Schlegel
661 <schlegel@riege.de> for reporting the bug and to
662 Dave Platt <dplatt@snulbug.mtview.ca.us> for suggesting
665 2. Modified the label and uuid analysis in order to be
666 self-contained (independant of kernel/libc headers). This
667 should fix the compile with older kernel/libc headers and
668 will preserve the functionality. Thanks to Bernhard Erdmann
669 <bernhard.erdmann@gmx.de> for reporting the bug.
671 3. The 'exclude inode' option, if applied to a directory
672 inode, excludes now correctly all the leaves of this
673 directory. Thanks to John R. Dennison
674 <gerdesas@users.sourceforge.net> for reporting the bug.
676 4. Fixed the '-e' option to disable the possibility
677 to exclude the root inode (which causes the dumps to
678 be unreadable by restore). Prevented array overflow
679 when multiple -e options are used.
681 5. Fixed dump to correctly interpret a filesystem argument
682 which is a mountpoint and it is not an absolute path
683 (as specified in the fstab). Thanks to Bernhard R. Erdmann
684 <be@berdmann.de> for reporting the bug.
686 6. Made dump able to backup files larger than 2 GB. Note that
687 dump still doesn't cope with files larger than 4 GB.
689 7. Restore the real uid and gid before invoking an external
690 RSH program (big hole when dump or restore is suid root!).
692 8. Get the values for the default tape device and the location
693 of fstab file from the system headers. Thanks to
694 Andreas Dilger <adilger@turbolinux.com> for the patch.
696 9. Made dump -w|-W report all recognized filesystems
697 present in either /etc/fstab or /etc/dumpdates, and present
698 the list in the same order as in fstab file. Thanks
699 to Andreas Dilger <adilger@turbolinux.com> for the patch.
701 10. Made dump's -a (automatic end of tape detection) the
702 default. Specifying one of -B, -c, -d or -s options will
703 override the EOM detection. Thanks to Andreas Dilger
704 <adilger@turbolinux.com> for the patch.
706 11. Save the ext2 filesystem label into the dump volume label.
707 Specifying a volume label on the command line (-L option)
708 will override this feature. Thanks to Andreas Dilger
709 <adilger@turbolinux.com> for the patch.
711 Changes between versions 0.4b18 and 0.4b19 (released August 20, 2000)
712 =====================================================================
714 1. Fixed the signal handling in dump (which I broke in 0.4b17)
715 which was causing several strange dump failures (dump
716 hanged or segmentation faults etc).
718 2. Specified the default blocksize in the dump man page.
720 3. Changed two info messages of restore to be written on stdout
721 instead of stderr in order to leave stderr only for errors
722 or warnings. Thanks to Stephen Atwell
723 <satwell@urbana.css.mot.com> for the suggestion.
725 4. Corrected an off by one calculation which prevented
726 dumping a directory having a 1 character name length.
727 Thanks to Bernhard Erdmann <bernhard.erdmann@gmx.de>
728 for reporting the bug.
730 5. Reinforce dump in order to allow only level 0 and no
731 -u option when dumping a subdirectory, and document
732 this in the man page. Thanks to Bernhard Erdmann
733 <bernhard.erdmann@gmx.de> for reporting the bug.
735 6. Fixed a small harmless bug in restore which caused
736 in some conditions hard links to be restored several
737 times (therefore generation some warning messages).
738 Thanks to Kenneth Porter <shiva@well.com> for
741 7. Updated the RPM spec file to the latest RedHat version,
742 providing FHS packaging and other cosmetic changes.
743 You will need RPM version >= 3.0.5 in order to build the RPM.
745 8. Updated the configure script to check for libtermcap
746 before checking for libreadline, because we need this
747 library in order to compile the readline support.
749 9. Made dump understand the LABEL= and UUID= notation
750 both in /etc/fstab and on the command line. Note that
751 you will need the /proc filesystem in order to use
752 these notations. Thanks to Erik Troan <ewt@redhat.com>
753 for providing the patch.
755 Changes between versions 0.4b17 and 0.4b18 (released June 30, 2000)
756 ===================================================================
758 1. Fixed a potential buffer overflow in restore. Thanks
759 to Stan Bubrouski <satan@fastdial.net> for reporting
762 2. Fixed a readline-related bug which prevented
763 'cat DUMPFILE | restore -i -f -' from working. Thanks
764 to Charles Karney <karney@users.sourceforge.net>
767 3. Changed a few "panic" into "exit", causing restore to
768 be more stable against some attacks (like the last one
769 reported on Bugtraq, although the last version of restore
770 was not vulnerable - just dumped core). Thanks to
771 Andreas Hasenack <andreas@conectiva.com.br> for reporting
774 4. Removed the suid-root bit on dump and restore in the
775 default build (and generated RPMs). It should be safer
776 now. Users who need the suid-root capabilities in order
777 to make network backups should read first the man page
778 of dump and enable the suid bit manually.
780 5. Added -ltermcap to the compile parameters for restore
781 when using readline support, in order to make the compile
782 process work on some systems (SuSE ?). Thanks to
783 Patrik Schindler <poc@pocnet.net> for reporting the bug.
785 Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000)
786 ====================================================================
788 1. The -F script is called now *only* at the end of a tape,
789 not at the end of the dump. Thanks to Christian Haul
790 <haul@informatik.tu-darmstadt.de> for the bug report.
792 Normally, the device name and the current volume number
793 are passed on the command line of the script. However,
794 if you want the old style script (with no arguments
795 passed on the command line), you can enable it in
796 configure with the --enable-oldstylefscript.
798 2. Use posix signal handling to preserve dump functionality
799 with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for
802 3. Made the exit code of restore in case of a 'C'ompare
803 command reflect the result of the compare. An exit status
804 of 0 means the dump archive is correct, 1 means tape errors,
805 2 means that some files were modified. Thanks to Kenneth Porter
806 <shiva@well.com> for the suggestion.
808 4. Made (finally) quotes work in interactive restore.
810 5. Small fixes in order to allow dump to compile with a
811 really old e2fsprogs version. Thanks to Ian Zimmerman
812 <itz@speakeasy.org> for the bug report.
814 6. Add GNU readline capabilities to interactive restore.
815 Use configure's --enable-readline flag to enable this feature.
816 Thanks to Patrik Schindler <poc@pocnet.net> for the
819 7. Do the compare on the fly in restore 'C' mode (this will
820 allow not to exhaust the available /tmp space when
821 ccmparing large files). Thanks to Kenneth Porter
822 <shiva@well.com> for the suggestion.
824 Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000)
825 ====================================================================
827 1. Fixed some several duplicate 'DUMP: DUMP:' in the
830 2. Corrected the estimation of blocks to dump. Note that
831 this is still wrong for large directory inodes, due
832 to the size of a BSD directory entry on the tape
833 (estimation is based on the size of the ext2 directory,
834 which is smaller because it doesn't contain the null
835 character at the end).
837 3. Made dump report the total number of MB written to
838 tape at the end of run. Thanks to W. Reilly Cooley
839 <wcooley@nakedape.cc> for the patch.
841 4. Added the -X option to restore giving the possibility
842 to read the names of the files to be extracted/listed
843 from a text file (in addition of the command line).
844 Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the
847 5. Added the device name and the current volume number
848 as arguments to the end of tape script (dump -F option).
850 6. Made the multi-volume dump work again (after having
851 broken it in 0.4b15).
853 Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000)
854 ===================================================================
856 1. Added a prompt command in interactive restore mode. Thanks
857 to Andreas Dilger <adilger@home.com> for the patch.
859 2. Fixed a buffer overflow problem in dump (caused by
860 not checking the size of the filesystem parameter).
861 Thanks to Kim Yong-jun <loveyou@hackerslab.org> for
862 reporting this on Bugtraq (and to several dump users
863 who forwarded me his mail).
865 3. Added the '-F script' option to dump in order to
866 launch a script at the end of each tape (to be used
867 with a tape changer, or to notify the sysadmin by
870 4. Fixed a bug in restore compare code caused by the changes
873 5. Fixed the treatment of options using the old BSD syntax
874 in both dump and restore.
876 Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000)
877 =======================================================================
879 1. Fixed a bug in dump which may have caused invalid deleted
880 directories to be dumped out if they were deleted after the
881 mapping pass. This could occure on active filesystem and lead
882 to heap corruption (causing dump malfunction in many possible ways).
883 Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this
884 bug and submitting the patch.
886 2. Fixed the handling of the filesystem parameter in dump. A
887 '/mnt/disk' parameter caused the disk contents to be dumped,
888 but a '/mnt/disk/' parameter caused the mountpoint directory
889 to be dumped (generally an empty directory).
891 3. Improved the output of dump in order to tell which directory
892 it is currently dumping (when dumping a subtree).
894 4. Added the '-e' exclude inode option to dump. Thanks to
895 Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch.
897 5. Added a REPORTING-BUGS file in order to provide a guide
898 on how to correctly report a bug in dump/restore.
900 6. Fixed a restore problem when restoring a hard link to an inode
901 having the immutable or append-only attribute set. Thanks to
902 Ambrose Li <acli@mingpaoxpress.com> for submitting the patch.
904 7. Fixed a compatibility problem between dumps made on little
905 endian machines (the format was correct) and big endian
906 machines (the format was incorrect). This fix break the
907 compatibility with the older dumps made on big endian
908 machines (sparc, m86k, ppc etc). For the first time in
909 linux dump's history (I believe), the dumps made by *BSD,
910 Linux/alpha, Linux/sparc and Linux/x86 are compatible,
911 so interchangeable. Thanks to Rob Cermak
912 <cermak@ahab.rutgers.edu> for submitting the bug and
913 helping me test the fix.
915 8. Fixed the way dump reports the remaining percent/time, if
916 the number of blocks actually dumped exceeds the estimated
917 number of blocks. Thanks to Jean-Paul van der Jagt
918 <jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug.
920 Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000)
921 ======================================================================
923 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski
924 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug.
926 2. Removed the requirement to build the RPM as root from the
927 spec file. Thanks to Christian Weisgerber
928 <naddy@mips.rhein-neckar.de> for submitting this.
930 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs,
931 causing dump to block when dumping really huge filesystems.
932 Many thanks to Patrik Schindler <poc@pocnet.net> for
933 helping me find this bug.
935 4. Fixed the treatment for an interrupt signal when dump access
936 the remote tape through RSH. Thanks to Christian Weisgerber
937 <naddy@mips.rhein-neckar.de> for providing the patch.
939 5. Fixed a bug which was causing dump/restore to display
940 garbage characters instead of the remote host name.
942 Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000)
943 =====================================================================
945 1. Small fix in the dump man page. Thanks to Thorsten Kukuk
946 <kukuk@suse.de> for submitting the patch.
948 2. Fix for the exit code when using the size estimate option of
949 dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for
950 submitting the patch.
952 3. Handle EINTR in atomical reads/writes in dump, which was causing
953 dump to fail on some systems. Thanks to Eric Jergensen
954 <eric@dvns.com> for reporting the bug and submitting the patch.
956 4. Handle more than 16 characters for the device names in dumpdates.
957 (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for
958 tracking down the problem and proposing the solution.
960 5. Fixed a bug in dump which prevented the creation of the
961 dumpdates file when doing a 0-level dump without already
962 having a dumpdates file. Thanks to Patrik Schindler
963 <poc@pocnet.net> for reporting the bug.
965 6. Changed the way dump 'S' flag reports the size estimate
966 from number of blocks into bytes (making it compatible
967 with the Solaris version, and simplifying things for
968 amanda users). Thanks to Jason L Tibbitts III
969 <tibbs@math.uh.edu> for reporting the bug.
971 7. Fixed a compatibility problem in linux/alpha dump tape format.
972 Now the linux/alpha dump are (again) compatible with the
973 other dump formats. But this breaks compatibility with
974 older dumps made on alpha. Thanks to Mike Tibor
975 <tibor@lib.uaa.alaska.edu> for helping me in finding this bug.
977 Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
978 ======================================================================
980 1. Added a '--enable-kerberos' to configure.
982 2. Added a 'S' option to dump which determines the amount of space
983 that is needed to perform the dump without actually doing it, similar
984 to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
985 <cermak@ahab.rutgers.edu>.
987 3. Added a 'M' multi-volume option to dump and restore which enables
988 dumping to multiple files (useful when dumping to an ext2
989 partition to make several dump files in order to bypass the 2GB
990 file size limitation). The 'f' argument is treated as a prefix and
991 the output files will be named <prefix>001, <prefix>002 etc. With
992 the 'M' flag, restore automatically selects the right file without
993 asking to enter a new tape each time.
995 4. Fixed a memory leak which was causing dump to grow very big
996 (270MB when dumping a 10GB filesystem...). Thanks to Jason
997 Fearon <jasonf@netrider.org.au> for reporting the bug.
999 Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
1000 ======================================================================
1002 1. Make configure test if the system glob routines support
1003 extended syntax (ALTDIRFUNC). If not, use the internal glob
1004 routines instead of system ones. Thanks to Bernhard Sadlowski
1005 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
1006 and helping me resolve this and other minor libc5 compiling
1009 2. Fix a problem when dumping a ext2fs with the 'filetype'
1010 feature enabled. Thanks to Patrick J. LoPresti
1011 <patl@cag.lcs.mit.edu> for reporting the bug and to
1012 Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.
1014 3. Made the nodump flag work on directories. A directory which
1015 has the nodump flag gets never dumped, regardless of its
1018 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
1019 which allows dump on an active ext3 filesystem. However, this
1020 is a "quick and dirty" patch which enables backup of an ext3
1021 filesystem through the ext2 compatibility (by ignoring the
1022 NEEDS_RECOVERY bit). The journal file is not recognized and
1023 it is dumped (it should not).
1025 5. Test the superblock compatibility flags when dumping, in order
1026 to be sure that we know how to deal with specific features.
1028 Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
1029 ====================================================================
1031 1. Use lchown instead of chown, fixing a possible security problem
1032 when restoring symlinks (a malicious user could use this
1033 to deliberately corrupt the ownership of important system files).
1034 Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
1035 this and providing the patch.
1037 Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
1038 ====================================================================
1040 1. Put dump sources under CVS, added Id tags in all files so
1041 one can use 'ident' on binary files.
1043 2. Added the dump/restore version in the usage text so one can
1044 easily verify the version he is using.
1046 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
1047 a va_start/va_end problem on linux-ppc (always call va_start
1048 va_end in pairs each time we use a vararg function).
1050 4. Added again the DT_* constants because old libc does not
1051 contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
1052 for submitting the bug report.
1054 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs
1055 this should enable dumping big (huge) filesystems.
1057 6. Added the RSH environment variable in order to be able to
1058 use a rsh replacement like ssh when doing remote backups (and
1059 bypass the security limitations of rcmd). Now you can do remote
1060 backups without being root (or making dump setuid root).
1062 7. Modified again the way dumpdates works. For incremental dumps,
1063 we need to read dumpdates even if we are not using 'u' option.
1064 Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
1067 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
1068 ===================================================================
1070 1. Removed the 'k' flag from the restore 'about' text if kerberos
1071 was not compiled in.
1073 2. Prototyped (f)setflags from e2fsprogs and corrected the calls
1074 to them (fsetflags takes a char*, setflags an open fd!).
1076 3. (f)setflags is called only if the flags aren't empty. If the
1077 file is a special file, a warning is printed, because changing
1078 flags implies opening the device. Normally, a special file
1079 should not have any flag... (Debian bug #29775, patch provided
1080 by Abhijit Dasgupta <abhijit@ans.net>).
1082 4. Made possible to dump a file system not mentioned in /etc/fstab.
1083 (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
1085 5. Changed the default behaviour to not create dumpdates
1086 unless 'u' option is specified. Removed the old "debian-patch"
1087 which provided the same thing. (Debian bug #38136, #33818).
1089 6. Removed all those dump*announce, since they were getting old...
1091 7. Added warning messages if dumpdates does not exist and
1092 when an inferior level dump does not exist (except for a level 0
1095 8. Debugged the glob calls in interactive mode: restore used a
1096 dirent struct which was different from the /usr/include/dirent.h
1097 one (this used to work, is it a glibc2 change?), so none of the
1098 compat glob (which used /usr/include/dirent.h) or the system glob
1099 worked. Restore use now the system dirent (and the system
1100 DT_* constants), which are compatible with BSD ones.
1102 9. Added a configure flag (--with-dumpdatespath) to specify
1103 the location of dumpdates file. By default, it is
1106 10. Added the "AUTHOR" and "AVAILABILITY" sections and
1107 included the current date/version in man pages.
1109 11. Corrected the estimation of remaining time when
1110 the operator doesn't change the tapes quickly enough. This
1111 was an old bug, I thought I corrected it, and discovered
1112 that in fact it was corrected in two different places, so
1113 the results canceled each other...
1115 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
1116 ===================================================================
1118 1. Integrated multiple patches from RedHat, Debian and SuSE:
1120 - tweak dump/itime.c to not try to read dumpdates if the 'u' option
1122 - several fixes in the man pages.
1123 - update the default tape device to /dev/st0.
1124 - many updates for Linux Alpha (byte ordering, size_t etc).
1126 - use environment variable for TMPDIR (instead of /tmp).
1127 - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
1128 - workaround egcs bug (RedHat bugs #4281 and #2989).
1129 - wire $(OPT) throughout Makefile's.
1131 2. Upgrade the dump revision to 1, making possible to dump filesystems
1132 made with e2fsprogs-1.15 or newer. Nothing seems to break...
1134 3. Fix some compile warnings, prototype all functions.
1136 4. Use glibc err/glob instead of internal compatibility
1137 routines (only if available).
1139 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
1140 by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
1142 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
1143 ======================================================================
1145 1. Integrated the changes from FreeBSD-3.1-RELEASE
1146 (mostly bug fixes, buffer overruns, dump has now an "automatic
1147 tape length calculation" flag, dump/restore can use kerberos now
1148 (this is NOT tested), use environment variables for TAPE and
1151 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
1153 3. Corrected a bug in restore when using 'C' option with multi-volumes
1154 tapes (files splited accros two tapes give "size changed" errors
1157 4. Corrected the long standing bug when dumping multiple tapes.
1158 This works for me, needs further testing.
1160 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
1161 ====================================================================
1163 1. Dump now runs correctly on kernels 2.1.x
1164 Fix made by Gerald Peters <gapeters@worldnet.att.net>
1166 Changes between versions 0.4b2 and 0.4b3
1167 ========================================
1169 1. Use realpath() if available
1171 2. Report statistics
1173 Changes between versions 0.4b1 and 0.4b2
1174 ========================================
1176 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
1179 2. Fixed restore to make it able to read FreeBSD 2.x dumps again
1181 3. Fixed configure.in to correctly handle --enable-rmt
1183 Changes between versions 0.3 and 0.4b1
1184 ======================================
1186 1. Integrated the changes from 4.4BSD-Lite2
1188 2. Integrated the patches from Debian and Red Hat
1190 3. Portability changes: use the __u32, __u16, __s32, and __s16 types
1192 4. Changed dump to use the Ext2fs library to get block addresses. This
1193 should solve the endianness problem on SparcLinux.
1195 5. Created a configure.in file (shamelessly stolen from the e2fsprogs
1196 distribution's one) to use autoconf
1198 6. Fixed a few minor bugs
1200 Changes between versions 0.2e and 0.2f
1201 ======================================
1203 1. Added the creation of named pipes (fifos) in restore.
1205 2. Added the -N flag in the restore manual page.
1207 3. Added the file kernel.patch which contains the llseek() optimization
1208 patch for 1.2.x kernels.
1210 4. Fixed a bug in the restoration of symbolic links: owner and group were
1213 5. Integrated some changes from FreeBSD 2.2.
1215 6. Added a call to ftruncate() after restoring each file to restore
1216 correctly files ending by a hole.
1218 Changes between versions 0.2d and 0.2e
1219 ======================================
1221 1. Fixed a bug in the "set owner/mode" process. Every file was restored
1222 with owner = root (0) and group = root/wheel/whatever (0).
1224 Changes between versions 0.2c and 0.2d
1225 ======================================
1227 1. Dump is now able to backup 2GB+ filesystems.
1229 2. Dump and restore can now be linked as static binaries.
1231 Changes between versions 0.2b and 0.2c
1232 ======================================
1234 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
1236 Changes between versions 0.2a and 0.2b
1237 ======================================
1239 1. Really fixed the bug that I should have corrected in 0.2a.
1241 2. Enabled optimization again.
1243 Changes between versions 0.2 and 0.2a
1244 =====================================
1246 1. Disabled the optimization during compilation.
1248 Changes between versions 0.1 and 0.2
1249 ====================================
1251 1. Fixed a bug in fstab.c which caused a null pointer to be stored in
1252 the fs_type field (actually, I modified the file fstab.c to make it
1253 use the mntent functions).
1255 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups
1256 made by dump should be readable by the BSD restore and backups made
1257 by the BSD dump should be readable by restore. Unfortunately, this
1258 means that the dump format has changed between version 0.1 and version
1261 3. Dump is now able to backup a subtree, it is no longer limited to whole
1262 filesystems like the BSD version.
1264 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger
1267 Changes between versions 0.0 and 0.1
1268 ====================================
1270 1. Now create links rdump and rrestore during the `make install' step.
1272 2. Linux port specific bugs added to the manual pages
1274 3. Incorrect estimation of the number of tapes blocks fixed when doing
1275 incremental backups.
1277 4. Better ls-like format in restore in interactive mode.
