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 Changes between versions 0.4b33 and 0.4b34 (released April 18, 2003)
12 ====================================================================
14 1. Fixed the INSTALL file to reflect the actual install paths.
15 Thanks to David Ronis <ronis@ronispc.chem.mcgill.ca> for
18 2. Fixed the configure script to only check for headers presence
19 instead of trying to compile them. This should fix issues
20 with old build environments. Thanks to Kari Lempiainen
21 <kari@funky.pp.fi> for reporting the bug.
23 3. Fixed restore to correctly ignore sockets when comparing
24 a dump (as socket cannot be properly restored anyway). Thanks
25 to Gunther Reiszig <gunther@mit.edu> for reporting the bug.
27 4. Fixed restore to correctly access the archive file (-A argument)
28 even when using a remote tape. Thanks to Fabrice Bellet
29 <fabrice@bellet.info> for reporting the bug.
31 5. Fixed (again) handling of long (largefile) seeks in rmt.
32 Thanks to Fabrice Bellet <fabrice@bellet.info> for reporting
35 6. Fixed restore corner case when dealing with large block sizes
36 dump is able to write now (-b 1024). Thanks to Fabrice Bellet
37 <fabrice@bellet.info> for reporting the bug.
39 7. Fixed a bug preventing dump to access a filesystem having
40 a label exactly 16 bytes in length. Thanks to <minduni@ti-edu.ch>
41 for reporting the bug.
43 8. Made dump store dump dates using explicit timezones, fixing a
44 problem with incremental dumps if the timezone is modified
45 between the dumps. Thanks to Philippe Troin <phil@fifi.org> for
46 the bug report and the patch.
48 9. Fixed a bug encountered when dumping individual files (not full
49 filesystems or directories) and dangling symbolic links happen
50 to be in the list of files. For as far as dump is concerned,
51 dangling symbolic links are allowed, and are dumped as is.
52 Thanks to Jin-su Ahn <jsahn@ee.snu.ac.kr> for reporting the
53 bug and providing the fix.
55 10. Fixed open and creation modes and permissions for QFA and
56 table-of-contents files in dump and restore. Thanks to
57 Philippe Troin <phil@fifi.org> for the patch.
59 11. Fixed the archive file descriptor handling enabling it to be 0.
60 This can happen in some cases when shell redirections are used.
61 Thanks to Philippe Troin <phil@fifi.org> for the patch.
63 12. Delayed the opening of archive file until after suid had been
64 dropped (fixing a possible security issue if dump is suid).
65 Thanks to Philippe Troin <phil@fifi.org> for the patch.
67 13. Fixed the 'S' command handling in the rmt client part.
68 Thanks to Philippe Troin <phil@fifi.org> for the patch.
70 14. Modified the end-of-tape script handling to print out statistics
71 (and stop the timer) before launching the eot script. Also, the eot
72 script does not get run anymore when using -M (which makes sense) or
73 when multiple tapes are listed on the command line
74 (-f tape0,tape1,tapen) (which also makes sense).
75 Thanks to Philippe Troin <phil@fifi.org> for the patch.
77 15. Relicensed dump/restore under the 'revised' BSD license, as per
78 ftp://ftp.cs.berkeley.edu/ucb/4bsd/README.Impt.License.Change.
80 16. Added LZO compression to dump. This new compression method has
81 the advantage of being super fast, thus not killing tape streaming
82 on slow machines. Thanks to Helmut Jarausch
83 <jarausch@igpm.rwth-aachen.de> for the patch and to
84 Markus Oberhumer <markus@oberhumer.com> for giving special permission
85 to include his miniLZO project (GPL licensed) in dump/restore.
87 17. Some small buffer overruns fixes in rmt. Thanks to Antonomasia
88 <ant@notatla.demon.co.uk> for reporting the bugs.
90 18. Added a special rmt version which can do encryption when writing
91 to tape. Read examples/encrypted_rmt/README for details on
92 how to enable and configure it. Thanks to Ken Lalonde
93 <ken@globalremit.com> for the patch.
95 19. Made dump work with 2.5 kernel end of tape early warning semantics.
96 Thanks to Kai Makisara <Kai.Makisara@kolumbus.fi> for the patch.
98 20. Fixed a bug which caused dump -w|-W not to work anymore, because
99 the fs_freq and fs_passno fields in /etc/mtab are always set
100 to 0 0. Thanks to Trent Piepho <xyzzy@speakeasy.org> for
103 Changes between versions 0.4b32 and 0.4b33 (released February 10, 2003)
104 =======================================================================
106 1. Added a note in the restore man page clarifying the question
107 'set the permissions on the current directory ?' asked by
108 restore at the end of treatment in -i and -x modes.
110 2. Fixed the endianess issues when reading compressed tapes.
111 Thanks to Dark Force <daq4th@users.sourceforge.net> for
112 reporting this bug and providing test cases.
114 3. Fixed the "ACL won't be dumped" warning message (which showed
115 an extra, unrelated error message). Thanks to Dragan Krnic
116 <dkrnic@lycos.com> for reporting this bug.
118 4. Made dump look first into /etc/mtab, then into /etc/fstab
119 when searching for filesystem paths. Also fixed some problems
120 caused by binding mounts or multiple block device mounts.
121 Thanks to Matus Uhlar <uhlar@fantomas.sk>, Elliott Mitchell
122 <ehem@m5p.com>, Greg Edwards <gedwards@users.sourceforge.net>,
123 Brian Hoy <brian.hoy@opus.co.nz>. (fixes Debian bugs #147086
124 and #160305, Sourceforge bugs #618699 and #679832).
126 5. Made dump's -I option accept the value '0' meaning all the
127 read errors will be ignored. This can be useful when running
128 dump from unattended sessions (like cron jobs). Thanks to
129 John I Wang <jiwang@users.sourceforge.net> for the suggestion.
131 6. Fixed the output of dump to indicate 'blocks' instead of
132 'tape blocks' in the various messages (blocks are always
133 1 Kilobyte, tape blocks are 1 BK * '-b' argument), and
134 made it clearly print the current blocksize at the start of
135 a dump. Thanks to Michal Szymanski <msz@astrouw.edu.pl> for
138 7. Made rmt understand long (largefiles) seeks.
140 8. Fixed build with very old versions of libext2fs, where
141 EXT2_FT_* constants were undefined.
143 9. Made dump accept the dumpdates path on the command line
144 (-D file option) instead of using only the hardcoded one.
145 Thanks to Piete Brooks <pb22@users.sourceforge.net> for the
148 10. Enabled rmt, LFS, readline, QFA options by default in
149 ./configure. Updated the configure process (new versions
150 of config.guess, config.sub etc).
152 Changes between versions 0.4b31 and 0.4b32 (released November 15, 2002)
153 =======================================================================
155 1. Changed dump to use fcntl(F_SETLK) style locking instead
156 of flock() when locking the dumpdates file. With the old
157 locking scheme, a local user having read rights on the
158 dumpdates file could be able to do a Denial of Service attack
159 on dump. In order to lock the dumpdates file with the new
160 scheme, the user would need to have write access on the file.
161 Thanks to Richard Johnson <Richard.Johnson3@ey.com> for
162 reporting the bug (originally a bugtraq post).
164 2. Fixed interactive 'ls' which caused spurious errors warnings
165 about 'undefined filetypes' detected. Thanks to Jorgen Ostling
166 <jorgen_ostling@users.sourceforge.net> for reporting this
169 3. Fixed dump's estimate when dealing with sparse inodes.
171 4. Modified dump to allow setting a blocksize bigger than 32kB
172 (raised the limit to 1024kB), because newer hardware needs
173 this for proper operation. Thanks to Dirk Traenapp
174 <dtraenapp@users.sourceforge.net> for reporting this.
176 5. Fixed a bug causing Dump to stop and report an error if an
177 inode number in the exclude file was followed by some amount
178 of whitespace. Thanks to Jeffrey Sofferin
179 <sofferin@users.sourceforge.net> for reporting this bug.
181 6. Fixed a bug which caused restore, in some particular cases,
182 to ask some 'scary' questions and leave a bunch of RSTTMP
183 directories behind when restoring incremental tapes. Thanks
184 to Philippe Troin <phil@fifi.org> for reporting this bug and
185 providing the test cases.
187 7. Changed the wording when inodes are excluded from dump:
188 replaced 'Added inode 7 to exclude list' with
189 'Excluding inode 7 (resize inode) from dump', as suggested
190 by Elliott Mitchell <ehem@m5p.com> in a Debian bug report.
192 Changes between versions 0.4b30 and 0.4b31 (released July 30, 2002)
193 ===================================================================
195 1. Fixed rmt open flags transmission (GNU's symbolic syntax over
196 rmt) which I broke in 0.4b29. Thanks to Eros Albertazzi
197 <eros@lamel.bo.cnr.it> for reporting the bug.
199 Changes between versions 0.4b29 and 0.4b30 (released July 25, 2002)
200 ===================================================================
202 1. Made dump print out the ext2 logical block number in case of a read
203 error, which can be given as an argument to debugfs' ncheck command,
204 in order to find out the affected inode. Added note about this
205 usage in dump's man page.
207 2. Fixed a problem in restore when reading tapes written on big
208 endian machines with very old versions of dump. The patch was
209 contributed by George Helffrich <george@geology.bristol.ac.uk>.
211 3. Fixed the tape length calculation when using large tapes
212 and compression. Thanks to Georg Lippold
213 <g_lippold@sourceforge.net> for reporting the bug.
215 4. Added a new set of examples in dump_on_cd_2 directory, based
216 on dump_on_cd examples but somewhat enhanced, supporting DVD
217 media, and localized in english and german. Thanks to
218 Georg Lippold <g_lippold@sourceforge.net> for the new scripts.
220 5. Made dump save 32 bit UID/GID. Internally, this was achieved
221 by switching from the old BSD inode format to the new BSD
222 inode format, which means that the tape format was changed.
223 However, since all restore versions out there should
224 transparently support both inode formats, the change should
225 have no side effects. Thanks to John Yu <jky@cs.bu.edu> for
228 6. Fixed a lot of warnings in the code shown when compiling
229 with 'gcc -W'. Thanks to Matthias Andree
230 <matthias.andree@stud.uni-dortmund.de> for reporting this.
232 7. Fixed a small markup bug in the dump man page. Thanks to
233 Eric S. Raymond <esr@minx.thyrsus.com> for submitting the
236 8. Rewrote entirely the man pages using the tmac.an macro
237 package (Linux man page format) instead of the original BSD
238 format. They should be now cleaner and easier to modify.
240 Changes between versions 0.4b28 and 0.4b29 (released June 8, 2002)
241 ==================================================================
243 1. Fixed a problem in the rmt ioctl command, where ioctl's issued from
244 non Linux clients were misinterpreted. The description of the problem
245 (incompatible numbering in Linux mtio opcodes) is documented at
246 ftp://ftp.fokus.gmd.de/pub/unix/star/README.mtio . Thanks to
247 Jörg Schilling <schilling@fokus.gmd.de> for reporting this bug and
248 providing an excellent, cross-platform replacement for rmt in his
251 2. Fixed a bug reported by Andy Mentges <amentges@jumpline.com>
252 which caused restore to fail when the inode maps were not entirely
253 contained on the first volume (when using really small volumes or
254 when dumping a huge number of inodes).
256 3. Fixed a problem in dump, where files in subdirectories of directories
257 that have the nodump flag set (or being excluded with -e/-E) were
258 sometimes incorrectly dumped (instead of being excluded). The original
259 fix is from David C Lawrence <tale@dd.org> in the FreeBSD version
260 of dump: http://www.FreeBSD.org/cgi/query-pr.cgi?pr=32414
261 Thanks to Ted Grzesik <tedgyz@roostme.com> for reporting the bug and
262 help testing the patch.
264 4. Added some example scripts from Gerd Bavendiek <bav@epost.de>
265 which makes one able to pipe the output of dump, by the net, to
266 a remote CD-burner server.
268 5. Made dump use O_CREAT|O_TRUNC both locally and remotely (over rmt),
269 and use GNU's symbolic syntax over rmt instead of numerical values
270 to assure multiple platform compatibility.
272 6. Documented the -d option in restore.
274 7. Added a -v (verbose) mode to dump. For now it just prints the number
275 of the inode being dumped, but this could evolve in future versions
276 to include interesting debugging output.
278 8. Added a -o flag to restore, which automatically restores the current
279 directory permissions in -i or -x mode, without asking the operator
280 whether to do so. Patch submitted by Tony Clayton <tonyc@e-smith.com>
281 and Peter Samuel <peters@e-smith.com>.
283 Changes between versions 0.4b27 and 0.4b28 (released April 12, 2002)
284 ====================================================================
286 1. Fixed a bug in the QFA feature which could have caused
287 a bad tape positionning on restore (causing extra delays in
288 restore). Credits go to Uwe Gohlke <uwe@ugsoft.de>.
290 2. Added a small note in the dump man page specifying that
291 there should be no white space between the option letter and
292 the -j or -z parameter, thanks to Kenneth Porter <shiva@well.com>
294 3. Made restore work with older versions of the readline library,
295 by checking in configure for several extended symbols. Restore
296 can now be compiled with a readline as old as the 2.0 release
297 (though it may be a good idea to upgrade it to a more recent
298 version...). Thanks to Andrew Donkin <ard@waikato.ac.nz> for
299 reporting the build failures.
301 4. Fixed a performance problem with the QFA file creation in
302 dump, which made unnecessary seeks on the tape slowing down
303 the dump. Thanks to Andrew Donkin <ard@waikato.ac.nz> for
304 reporting this issue.
306 5. Removed the inclusion of some kernel headers in the dump
307 source, which prevented the compile in some kernel/glibc
308 headers/architecture combination. Thanks to Bdale Garbee
309 <bdale@gag.com> for reporting the bug.
311 6. Added the appropriate error message when dump fails to
312 open the output file for writing. Thanks to Amith Varghese
313 <amithv@yahoo.com> for reporting this bug.
315 7. Made restore able to understand large Solaris ufsdump tapes
316 (containing inodes bigger than 4194304). Sun have introduced
317 an "extension" to the dump tape format when dealing with
318 those inodes, which was uncorrectly handled by Linux restore.
319 Thanks to Uwe Gohlke <uwe@ugsoft.de> for reporting the bug and
320 providing a test case.
322 8. Added the -m parameter to dump which optimises the output for
323 inodes having been changed but not modified since the last dump
324 ('changed' and 'modified' have the meaning defined in stat(2)).
325 For those inodes, dump will save only the metadata, instead of
326 saving the entire inode contents. Inodes which are either
327 directories or have been modified since the last dump are saved
328 in a regular way. Uses of this flag must be consistent, meaning
329 that either every dump in an incremental dump set have the flag,
332 Changes between versions 0.4b26 and 0.4b27 (released February 15, 2002)
333 =======================================================================
335 1. Fixed behaviour of dump when exceeding resource limits
338 2. Added the -L flag to restore to allow the user to specify a
339 maximal allowed number of miscompares when using restore
340 with the -C option to check the backup.
342 3. Detailed the manual entry for the -N option of restore.
344 4. Added the -a flag to restore to make able doing unattended
345 restores in -i or -x mode (automatically walks through the
346 multiple dump volumes).
348 5. Extended the QFA mode to work with local files and/or
349 remote tapes and files. This way, restore can know in advance
350 the tape number and the offset for the inodes to extract and
351 can minimize the extraction time by seeking directly to the
354 6. Added the -A <archive> option to both dump and restore,
355 which makes dump to archive a dump table-of-contents in
356 the specified file to be used by restore to determine
357 whether a file is in the dump file that is being restored.
358 (the archive file syntax is also compatible with the
359 Solaris ufsdump generated one).
361 7. Small fix in restore making it able to read some (broken ?)
362 Solaris ufsdump tapes.
364 8. Fixed dump to correctly recognise the root filesystem when using
365 ext2 disk labels (LABEL=/). Thanks to John Yu <jky@it.bu.edu>
366 for reporting this bug.
368 9. Added the -P <file> option to restore to create a
369 Quick File Access file from an already made dump. Patch
370 contributed by Uwe Gohlke <uwe@ugsoft.de>.
372 10. Made restore compile and run on Solaris, making it a
373 possible replacement for the standard ufsrestore. Port was
374 contributed by Uwe Gohlke <uwe@ugsoft.de>.
376 Changes between versions 0.4b25 and 0.4b26 (released January 7, 2002)
377 =====================================================================
379 1. Added a set of backup scripts from Eugenio Diaz
380 <getnito@yahoo.com> in the examples section. It features
381 automatic (cron based) full and incremental dumping of
382 several filesystems on a separate filesystem.
384 2. Fixed a off-by-one miscalculation which disabled dumping
385 a one letter subdirectory. Thanks to Chris Siebenmann
386 <cks@utcc.utoronto.ca> for reporting the bug.
388 3. Fixed several restore bugs occuring when trying to
389 restore some missing files on the tape. Thanks to Chris
390 Siebenmann <cks@utcc.utoronto.ca> for reporting the bug.
392 4. Fixed --with-ldopts configure argument passing, installing from
393 a separate object directory, makefile cleanups contributed
394 by <splite@purdue.edu>.
396 5. Fix a bug which could caused, in some conditions, the highest
397 number inode of a filesystem, to not be dumped. Many thanks
398 to Chris Siebenmann <cks@utcc.utoronto.ca> for helping me
401 Changes between versions 0.4b24 and 0.4b25 (released November 17, 2001)
402 =======================================================================
404 1. Added a mini howto from Patrick Walsh in the examples
407 2. Minor man pages syntax corrections. Thanks to
408 Chris Danis <screechco@home.com> for reporting the bugs.
410 3. Added a script from David B. Peterson <dave@toppledwagon.com>
411 to the examples section. It features dumping several
412 filesystems to a remote tape drive upon ssh.
414 4. Added a patch provided by Richard Jones <rich@annexia.org>
415 which allows BRADEMAX (number of read errors tolerated by
416 dump) to be adjusted using the -I option.
418 5. Fixed a bug which disabled doing "restore -C -f -". Thanks
419 to Clemens Stiglechner <a9401816@unet.univie.ac.at> for the
422 6. Add the -l option to restore to specify if, when doing a
423 remote restore, the file used to access the backup is a
424 regular file (the defaults being a tape drive). Restore needs
425 to know this information when reading a remote compressed
426 dump. Previously, this information was autodetected, but
427 the autodetection code fails (with ioctl: Inappropriate ioctl
428 for device) when using a non Linux remote box. Thanks to
429 many users and especially to Eros Albertazzi
430 <eros@lamel.bo.cnr.it> for reporting this.
432 7. Found a workaroung for the dump deadlock problem (3 childs
433 stuck in pause(), father in read()). The workaround seems
434 to work for me and several beta-testers. If it doesn't work
435 for you, please report back.
437 8. Updated the RPM spec file (BuildPrereq, URL etc).
439 Changes between versions 0.4b23 and 0.4b24 (released September 12, 2001)
440 ========================================================================
442 1. Fixed the permissions of a newly created QFA file by dump.
444 2. Cleaned up the source of dump (the external variables
445 definition was a complete mess, making possible to have
448 3. Fixed restore to use the full tape volume path when doing
449 a compare (since it changes the working directory to the
450 filesystem being compared in the process).
452 4. Added the -q option to dump which makes dump abort
453 whenever it needs operator attention. It should be
454 easier to use dump in scripts with this option.
456 5. Detect the use of incompatible options to dump and
457 refuse them (like -a and -B options together).
459 6. Added bzip2 compression to dump/restore (use option -j level
460 to select it). Note that you will need a restore version
461 >= 0.4b24 in order to restore a bzip2 compressed dump.
462 The same warning as for the zlib compression applies:
463 the tape format of a bzip2 dump is not compatible with the
464 original BSD tape format.
466 7. Fixed a overflow problem in dump corrupting the dump when
467 very large files were encountered. Thanks to Vladimir Nadvornik
470 8. Added a ioctl(BLKFLSBUF) in dump which should flush the
471 kernel buffer/page cache before starting the dump, helping
472 a bit those who use dump on mounted filesystems. Thanks to
473 John Yu <jky@it.bu.edu> and to Theodore T'so <tytso@mit.edu>
476 9. Updated the RPM spec file following the RedHat changes
477 (dynamically linked binaries now in /usr/sbin etc).
479 10. Added a patch from Helmut Jarausch <jarausch@igpm.rwth-aachen.de>
480 which enables restore to recognise multi volume compressed dumps
481 done on CD. Included his scripts for dump (which pipe the dump
482 output directly into cdrecord) and restore. There is now
483 possible to to backups to CD on the fly!
485 Changes between versions 0.4b22 and 0.4b23 (released July 20, 2001)
486 ===================================================================
488 1. Fixed a buffer overflow in restore/tape.c. Patch provided by
489 Marcus Meissner (Caldera International Security Dept.).
491 2. Implement the Sun rmt extended protocol. Patch submitted
492 by Ian Gordon <iangordon@users.sourceforge.net>.
494 3. Check for the e2fsprogs header <ext2fs/ext2_fs.h> instead of
495 the linux kernel header. This ensures that dump always has the
496 latest version of this file. Patch submitted by
497 Andreas Dilger <adilger@turbolinux.com>.
499 4. Report any filesystem present in either /etc/fstab with a
500 positive passno or /etc/dumpdates in dump -w output.
501 Patch submitted by Andreas Dilger <adilger@turbolinux.com>.
503 5. Fixed the looping problem in dump introduced in the
506 6. Changed the -B option of dump to limit the size of
507 _compressed_ output per volume if compression is on.
508 Patch contributed by Helmut Jarausch
509 <jarausch@igpm.rwth-aachen.de>. Note however that, since
510 it is impossible to predict the size of the compressed
511 data before doing the compression, the -B limit is a bit
514 7. Fixed a bug in reading the operator typed file/tape path for
515 the next volume in restore.
517 8. Implemented a "-F script" option to restore which permits the
518 user to specify a script which will be launched at the
519 beginning of each tape, useful for automatic programming of
520 tape changers for example. See the restore man page for the
521 script parameters and return codes.
523 9. Small fix for the QFA routines provided by Uwe Gohlke
524 <uwe@ugsoft.de>, and some recommendations for QFA uses in
527 10. Fixed the multivolume restoring where making a mistake
528 to the 'Mount next tape' prompt caused several blocks to
531 11. Enhanced the -e option of dump to take as a parameter a
532 comma separated list of inode numbers.
534 12. Added the -E option to dump which specify a file containing
535 inode numbers to exclude from the dump.
537 13. Fixed the compressed multi-volume dump + restore.
539 Changes between versions 0.4b21 and 0.4b22 (released May 12, 2001)
540 ==================================================================
542 1. Made dump report the number of blocks dumped per volume.
543 Thanks to Kenneth Porter <shiva@well.com> for the suggestion.
545 2. Fix a bug in dump where waiting too much at the 'change volumes'
546 question caused the volume to be rewritten. Thanks to
547 Graham Reed <greed@users.sourceforge.net> for reporting the
548 bug and providing a patch.
550 3. Added a compression option to dump, contributed by Jerry
551 Peters <gapeters@worldnet.att.net>.
553 WARNING: the compression works only on files/pipes and
554 drives supporting variable block size.
556 WARNING2: tapes created using the compression feature are
557 incompatible with the standard dump tape format, and a
558 version of restore >= 0.4b22 will be needed for extraction.
560 4. Fixed some compilation problems for glibc 2.2.2 and 64 bit
561 architectures. Thanks to Paul Slootman <paul@debian.org> for
562 the patch and to Bdale Garbee <bdale@gag.com> for forwarding
565 5. Many cleanups (CPP defines, const char warnings, check of
566 ext2fs COMPAT flags, time_t cleanups, added libext2 version
567 in dump usage text) by Andreas Dilger <adilger@turbolinux.com>.
569 6. Made --prefix option work in configure. All the install path
570 are now based on the configure parameters.
572 7. Added the Quick File Access mode in dump/restore, contributed
573 by Uwe Gohlke <uwe@ugsoft.de>. In this mode, dump stores in
574 a file tape position for each inode, and this file is used by
575 restore (if called with parameter Q and the filename)
576 to directly position the tape at the file restore is currently
577 working on. This saves hours when restoring single files from
578 large backups, saves the tapes and the drive's head. Use
579 --enable-qfa option of configure to compile in the QFA support.
581 8. Added the possibility to dump several files and directories
582 in a single invocation of dump. Thanks to Uwe Gohlke
583 <uwe@ugsoft.de> for implementing this option.
585 9. Fixed the dumping and restoring of files with holes
586 (files ending with holes didn't get dumped or restored
589 10. Fixed a socket descriptor leak in dump, which leaved opened
590 3 file descriptors per dump process (and there is one dump
593 11. Fixed dump large file system support, by explicit use of
594 open64/lseek64/etc functions (explicit use needed because
595 e2fsprogs libraries don't behave well when compiled with
596 FILE_OFFSET_BITS=64).
598 Changes between versions 0.4b20 and 0.4b21 (released January 13, 2001)
599 ======================================================================
601 1. Fixed some bugs in the dump -w|-W logic introduced by
602 the previous version. Thanks to Andreas Dilger
603 <adilger@turbolinux.com> for his help on this one.
605 2. Fixed again a compilation problem when using old e2fs
606 headers (filesystem label related). Thanks to many users
607 who reported this stupid error.
609 3. Fixed a build problem on old lib5 based systems dealing with
610 _PATH_MNTTAB being undefined. Thanks to John Adams
611 <johna@onevista.com> for reporting the bug.
613 4. Improved the error detection in restore when creating
614 the temporary files in TMPDIR. Now restore will corectly
615 report a 'no space left on device' error instead of
616 strange errors which could imply an archive corruption.
617 Thanks to Gabriel Somlo <somlo@cs.colostate.edu> and
618 bgjenero <bgjenero@sympatico.ca> for reporting the bug.
620 5. Added the throughput information in dump's progression
621 messages. Thanks to Andreas Dilger <adilger@turbolinux.com>
624 6. Use libext2fs's inode scanning routines, which are particularly
625 robust when dealing with errors (especially when having some
626 bad blocks on the filesystem). Many thanks to Colin
627 <colin@horizon.com> for reporting the bug, investigating
628 the issues, finding a workaround, writing the patch and
629 fully testing it... (of course, if this patch will break
630 anything, he is to blame for :-)).
632 7. Made dump and restore LFS aware. Dump can dump a filesystem
633 containing large files, generate a large file on output and
634 restore can restore them. This feature is not enabled by
635 default, use --enable-largefile option of configure to enable
636 it (you need to have a LFS aware glibc though). Thanks to
637 Andrea Arcangeli <andrea@suse.de> for submitting the patch,
638 and to Theodore T'so <tytso@valinux.com> for his always
641 8. Made dump ask upon a tape write error if it should rewrite
642 the current volume (assume this is a bad tape) or if it should
643 assume an end-of-tape condition (useful for tape drives which
644 behaves badly at the end of the tape). Thanks to Andreas
645 Dilger <adilger@turbolinux.com> for the suggestion.
647 Changes between versions 0.4b19 and 0.4b20 (released November 10, 2000)
648 =======================================================================
650 1. Fixed a small compilation problem due to a change
651 in the definintion of the struct sigaction in
652 glibc 2.0 / libc5. Thanks to Gunther Schlegel
653 <schlegel@riege.de> for reporting the bug and to
654 Dave Platt <dplatt@snulbug.mtview.ca.us> for suggesting
657 2. Modified the label and uuid analysis in order to be
658 self-contained (independant of kernel/libc headers). This
659 should fix the compile with older kernel/libc headers and
660 will preserve the functionality. Thanks to Bernhard Erdmann
661 <bernhard.erdmann@gmx.de> for reporting the bug.
663 3. The 'exclude inode' option, if applied to a directory
664 inode, excludes now correctly all the leaves of this
665 directory. Thanks to John R. Dennison
666 <gerdesas@users.sourceforge.net> for reporting the bug.
668 4. Fixed the '-e' option to disable the possibility
669 to exclude the root inode (which causes the dumps to
670 be unreadable by restore). Prevented array overflow
671 when multiple -e options are used.
673 5. Fixed dump to correctly interpret a filesystem argument
674 which is a mountpoint and it is not an absolute path
675 (as specified in the fstab). Thanks to Bernhard R. Erdmann
676 <be@berdmann.de> for reporting the bug.
678 6. Made dump able to backup files larger than 2 GB. Note that
679 dump still doesn't cope with files larger than 4 GB.
681 7. Restore the real uid and gid before invoking an external
682 RSH program (big hole when dump or restore is suid root!).
684 8. Get the values for the default tape device and the location
685 of fstab file from the system headers. Thanks to
686 Andreas Dilger <adilger@turbolinux.com> for the patch.
688 9. Made dump -w|-W report all recognized filesystems
689 present in either /etc/fstab or /etc/dumpdates, and present
690 the list in the same order as in fstab file. Thanks
691 to Andreas Dilger <adilger@turbolinux.com> for the patch.
693 10. Made dump's -a (automatic end of tape detection) the
694 default. Specifying one of -B, -c, -d or -s options will
695 override the EOM detection. Thanks to Andreas Dilger
696 <adilger@turbolinux.com> for the patch.
698 11. Save the ext2 filesystem label into the dump volume label.
699 Specifying a volume label on the command line (-L option)
700 will override this feature. Thanks to Andreas Dilger
701 <adilger@turbolinux.com> for the patch.
703 Changes between versions 0.4b18 and 0.4b19 (released August 20, 2000)
704 =====================================================================
706 1. Fixed the signal handling in dump (which I broke in 0.4b17)
707 which was causing several strange dump failures (dump
708 hanged or segmentation faults etc).
710 2. Specified the default blocksize in the dump man page.
712 3. Changed two info messages of restore to be written on stdout
713 instead of stderr in order to leave stderr only for errors
714 or warnings. Thanks to Stephen Atwell
715 <satwell@urbana.css.mot.com> for the suggestion.
717 4. Corrected an off by one calculation which prevented
718 dumping a directory having a 1 character name length.
719 Thanks to Bernhard Erdmann <bernhard.erdmann@gmx.de>
720 for reporting the bug.
722 5. Reinforce dump in order to allow only level 0 and no
723 -u option when dumping a subdirectory, and document
724 this in the man page. Thanks to Bernhard Erdmann
725 <bernhard.erdmann@gmx.de> for reporting the bug.
727 6. Fixed a small harmless bug in restore which caused
728 in some conditions hard links to be restored several
729 times (therefore generation some warning messages).
730 Thanks to Kenneth Porter <shiva@well.com> for
733 7. Updated the RPM spec file to the latest RedHat version,
734 providing FHS packaging and other cosmetic changes.
735 You will need RPM version >= 3.0.5 in order to build the RPM.
737 8. Updated the configure script to check for libtermcap
738 before checking for libreadline, because we need this
739 library in order to compile the readline support.
741 9. Made dump understand the LABEL= and UUID= notation
742 both in /etc/fstab and on the command line. Note that
743 you will need the /proc filesystem in order to use
744 these notations. Thanks to Erik Troan <ewt@redhat.com>
745 for providing the patch.
747 Changes between versions 0.4b17 and 0.4b18 (released June 30, 2000)
748 ===================================================================
750 1. Fixed a potential buffer overflow in restore. Thanks
751 to Stan Bubrouski <satan@fastdial.net> for reporting
754 2. Fixed a readline-related bug which prevented
755 'cat DUMPFILE | restore -i -f -' from working. Thanks
756 to Charles Karney <karney@users.sourceforge.net>
759 3. Changed a few "panic" into "exit", causing restore to
760 be more stable against some attacks (like the last one
761 reported on Bugtraq, although the last version of restore
762 was not vulnerable - just dumped core). Thanks to
763 Andreas Hasenack <andreas@conectiva.com.br> for reporting
766 4. Removed the suid-root bit on dump and restore in the
767 default build (and generated RPMs). It should be safer
768 now. Users who need the suid-root capabilities in order
769 to make network backups should read first the man page
770 of dump and enable the suid bit manually.
772 5. Added -ltermcap to the compile parameters for restore
773 when using readline support, in order to make the compile
774 process work on some systems (SuSE ?). Thanks to
775 Patrik Schindler <poc@pocnet.net> for reporting the bug.
777 Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000)
778 ====================================================================
780 1. The -F script is called now *only* at the end of a tape,
781 not at the end of the dump. Thanks to Christian Haul
782 <haul@informatik.tu-darmstadt.de> for the bug report.
784 Normally, the device name and the current volume number
785 are passed on the command line of the script. However,
786 if you want the old style script (with no arguments
787 passed on the command line), you can enable it in
788 configure with the --enable-oldstylefscript.
790 2. Use posix signal handling to preserve dump functionality
791 with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for
794 3. Made the exit code of restore in case of a 'C'ompare
795 command reflect the result of the compare. An exit status
796 of 0 means the dump archive is correct, 1 means tape errors,
797 2 means that some files were modified. Thanks to Kenneth Porter
798 <shiva@well.com> for the suggestion.
800 4. Made (finally) quotes work in interactive restore.
802 5. Small fixes in order to allow dump to compile with a
803 really old e2fsprogs version. Thanks to Ian Zimmerman
804 <itz@speakeasy.org> for the bug report.
806 6. Add GNU readline capabilities to interactive restore.
807 Use configure's --enable-readline flag to enable this feature.
808 Thanks to Patrik Schindler <poc@pocnet.net> for the
811 7. Do the compare on the fly in restore 'C' mode (this will
812 allow not to exhaust the available /tmp space when
813 ccmparing large files). Thanks to Kenneth Porter
814 <shiva@well.com> for the suggestion.
816 Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000)
817 ====================================================================
819 1. Fixed some several duplicate 'DUMP: DUMP:' in the
822 2. Corrected the estimation of blocks to dump. Note that
823 this is still wrong for large directory inodes, due
824 to the size of a BSD directory entry on the tape
825 (estimation is based on the size of the ext2 directory,
826 which is smaller because it doesn't contain the null
827 character at the end).
829 3. Made dump report the total number of MB written to
830 tape at the end of run. Thanks to W. Reilly Cooley
831 <wcooley@nakedape.cc> for the patch.
833 4. Added the -X option to restore giving the possibility
834 to read the names of the files to be extracted/listed
835 from a text file (in addition of the command line).
836 Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the
839 5. Added the device name and the current volume number
840 as arguments to the end of tape script (dump -F option).
842 6. Made the multi-volume dump work again (after having
843 broken it in 0.4b15).
845 Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000)
846 ===================================================================
848 1. Added a prompt command in interactive restore mode. Thanks
849 to Andreas Dilger <adilger@home.com> for the patch.
851 2. Fixed a buffer overflow problem in dump (caused by
852 not checking the size of the filesystem parameter).
853 Thanks to Kim Yong-jun <loveyou@hackerslab.org> for
854 reporting this on Bugtraq (and to several dump users
855 who forwarded me his mail).
857 3. Added the '-F script' option to dump in order to
858 launch a script at the end of each tape (to be used
859 with a tape changer, or to notify the sysadmin by
862 4. Fixed a bug in restore compare code caused by the changes
865 5. Fixed the treatment of options using the old BSD syntax
866 in both dump and restore.
868 Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000)
869 =======================================================================
871 1. Fixed a bug in dump which may have caused invalid deleted
872 directories to be dumped out if they were deleted after the
873 mapping pass. This could occure on active filesystem and lead
874 to heap corruption (causing dump malfunction in many possible ways).
875 Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this
876 bug and submitting the patch.
878 2. Fixed the handling of the filesystem parameter in dump. A
879 '/mnt/disk' parameter caused the disk contents to be dumped,
880 but a '/mnt/disk/' parameter caused the mountpoint directory
881 to be dumped (generally an empty directory).
883 3. Improved the output of dump in order to tell which directory
884 it is currently dumping (when dumping a subtree).
886 4. Added the '-e' exclude inode option to dump. Thanks to
887 Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch.
889 5. Added a REPORTING-BUGS file in order to provide a guide
890 on how to correctly report a bug in dump/restore.
892 6. Fixed a restore problem when restoring a hard link to an inode
893 having the immutable or append-only attribute set. Thanks to
894 Ambrose Li <acli@mingpaoxpress.com> for submitting the patch.
896 7. Fixed a compatibility problem between dumps made on little
897 endian machines (the format was correct) and big endian
898 machines (the format was incorrect). This fix break the
899 compatibility with the older dumps made on big endian
900 machines (sparc, m86k, ppc etc). For the first time in
901 linux dump's history (I believe), the dumps made by *BSD,
902 Linux/alpha, Linux/sparc and Linux/x86 are compatible,
903 so interchangeable. Thanks to Rob Cermak
904 <cermak@ahab.rutgers.edu> for submitting the bug and
905 helping me test the fix.
907 8. Fixed the way dump reports the remaining percent/time, if
908 the number of blocks actually dumped exceeds the estimated
909 number of blocks. Thanks to Jean-Paul van der Jagt
910 <jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug.
912 Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000)
913 ======================================================================
915 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski
916 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug.
918 2. Removed the requirement to build the RPM as root from the
919 spec file. Thanks to Christian Weisgerber
920 <naddy@mips.rhein-neckar.de> for submitting this.
922 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs,
923 causing dump to block when dumping really huge filesystems.
924 Many thanks to Patrik Schindler <poc@pocnet.net> for
925 helping me find this bug.
927 4. Fixed the treatment for an interrupt signal when dump access
928 the remote tape through RSH. Thanks to Christian Weisgerber
929 <naddy@mips.rhein-neckar.de> for providing the patch.
931 5. Fixed a bug which was causing dump/restore to display
932 garbage characters instead of the remote host name.
934 Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000)
935 =====================================================================
937 1. Small fix in the dump man page. Thanks to Thorsten Kukuk
938 <kukuk@suse.de> for submitting the patch.
940 2. Fix for the exit code when using the size estimate option of
941 dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for
942 submitting the patch.
944 3. Handle EINTR in atomical reads/writes in dump, which was causing
945 dump to fail on some systems. Thanks to Eric Jergensen
946 <eric@dvns.com> for reporting the bug and submitting the patch.
948 4. Handle more than 16 characters for the device names in dumpdates.
949 (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for
950 tracking down the problem and proposing the solution.
952 5. Fixed a bug in dump which prevented the creation of the
953 dumpdates file when doing a 0-level dump without already
954 having a dumpdates file. Thanks to Patrik Schindler
955 <poc@pocnet.net> for reporting the bug.
957 6. Changed the way dump 'S' flag reports the size estimate
958 from number of blocks into bytes (making it compatible
959 with the Solaris version, and simplifying things for
960 amanda users). Thanks to Jason L Tibbitts III
961 <tibbs@math.uh.edu> for reporting the bug.
963 7. Fixed a compatibility problem in linux/alpha dump tape format.
964 Now the linux/alpha dump are (again) compatible with the
965 other dump formats. But this breaks compatibility with
966 older dumps made on alpha. Thanks to Mike Tibor
967 <tibor@lib.uaa.alaska.edu> for helping me in finding this bug.
969 Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
970 ======================================================================
972 1. Added a '--enable-kerberos' to configure.
974 2. Added a 'S' option to dump which determines the amount of space
975 that is needed to perform the dump without actually doing it, similar
976 to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
977 <cermak@ahab.rutgers.edu>.
979 3. Added a 'M' multi-volume option to dump and restore which enables
980 dumping to multiple files (useful when dumping to an ext2
981 partition to make several dump files in order to bypass the 2GB
982 file size limitation). The 'f' argument is treated as a prefix and
983 the output files will be named <prefix>001, <prefix>002 etc. With
984 the 'M' flag, restore automatically selects the right file without
985 asking to enter a new tape each time.
987 4. Fixed a memory leak which was causing dump to grow very big
988 (270MB when dumping a 10GB filesystem...). Thanks to Jason
989 Fearon <jasonf@netrider.org.au> for reporting the bug.
991 Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
992 ======================================================================
994 1. Make configure test if the system glob routines support
995 extended syntax (ALTDIRFUNC). If not, use the internal glob
996 routines instead of system ones. Thanks to Bernhard Sadlowski
997 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
998 and helping me resolve this and other minor libc5 compiling
1001 2. Fix a problem when dumping a ext2fs with the 'filetype'
1002 feature enabled. Thanks to Patrick J. LoPresti
1003 <patl@cag.lcs.mit.edu> for reporting the bug and to
1004 Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.
1006 3. Made the nodump flag work on directories. A directory which
1007 has the nodump flag gets never dumped, regardless of its
1010 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
1011 which allows dump on an active ext3 filesystem. However, this
1012 is a "quick and dirty" patch which enables backup of an ext3
1013 filesystem through the ext2 compatibility (by ignoring the
1014 NEEDS_RECOVERY bit). The journal file is not recognized and
1015 it is dumped (it should not).
1017 5. Test the superblock compatibility flags when dumping, in order
1018 to be sure that we know how to deal with specific features.
1020 Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
1021 ====================================================================
1023 1. Use lchown instead of chown, fixing a possible security problem
1024 when restoring symlinks (a malicious user could use this
1025 to deliberately corrupt the ownership of important system files).
1026 Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
1027 this and providing the patch.
1029 Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
1030 ====================================================================
1032 1. Put dump sources under CVS, added Id tags in all files so
1033 one can use 'ident' on binary files.
1035 2. Added the dump/restore version in the usage text so one can
1036 easily verify the version he is using.
1038 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
1039 a va_start/va_end problem on linux-ppc (always call va_start
1040 va_end in pairs each time we use a vararg function).
1042 4. Added again the DT_* constants because old libc does not
1043 contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
1044 for submitting the bug report.
1046 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs
1047 this should enable dumping big (huge) filesystems.
1049 6. Added the RSH environment variable in order to be able to
1050 use a rsh replacement like ssh when doing remote backups (and
1051 bypass the security limitations of rcmd). Now you can do remote
1052 backups without being root (or making dump setuid root).
1054 7. Modified again the way dumpdates works. For incremental dumps,
1055 we need to read dumpdates even if we are not using 'u' option.
1056 Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
1059 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
1060 ===================================================================
1062 1. Removed the 'k' flag from the restore 'about' text if kerberos
1063 was not compiled in.
1065 2. Prototyped (f)setflags from e2fsprogs and corrected the calls
1066 to them (fsetflags takes a char*, setflags an open fd!).
1068 3. (f)setflags is called only if the flags aren't empty. If the
1069 file is a special file, a warning is printed, because changing
1070 flags implies opening the device. Normally, a special file
1071 should not have any flag... (Debian bug #29775, patch provided
1072 by Abhijit Dasgupta <abhijit@ans.net>).
1074 4. Made possible to dump a file system not mentioned in /etc/fstab.
1075 (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
1077 5. Changed the default behaviour to not create dumpdates
1078 unless 'u' option is specified. Removed the old "debian-patch"
1079 which provided the same thing. (Debian bug #38136, #33818).
1081 6. Removed all those dump*announce, since they were getting old...
1083 7. Added warning messages if dumpdates does not exist and
1084 when an inferior level dump does not exist (except for a level 0
1087 8. Debugged the glob calls in interactive mode: restore used a
1088 dirent struct which was different from the /usr/include/dirent.h
1089 one (this used to work, is it a glibc2 change?), so none of the
1090 compat glob (which used /usr/include/dirent.h) or the system glob
1091 worked. Restore use now the system dirent (and the system
1092 DT_* constants), which are compatible with BSD ones.
1094 9. Added a configure flag (--with-dumpdatespath) to specify
1095 the location of dumpdates file. By default, it is
1098 10. Added the "AUTHOR" and "AVAILABILITY" sections and
1099 included the current date/version in man pages.
1101 11. Corrected the estimation of remaining time when
1102 the operator doesn't change the tapes quickly enough. This
1103 was an old bug, I thought I corrected it, and discovered
1104 that in fact it was corrected in two different places, so
1105 the results canceled each other...
1107 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
1108 ===================================================================
1110 1. Integrated multiple patches from RedHat, Debian and SuSE:
1112 - tweak dump/itime.c to not try to read dumpdates if the 'u' option
1114 - several fixes in the man pages.
1115 - update the default tape device to /dev/st0.
1116 - many updates for Linux Alpha (byte ordering, size_t etc).
1118 - use environment variable for TMPDIR (instead of /tmp).
1119 - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
1120 - workaround egcs bug (RedHat bugs #4281 and #2989).
1121 - wire $(OPT) throughout Makefile's.
1123 2. Upgrade the dump revision to 1, making possible to dump filesystems
1124 made with e2fsprogs-1.15 or newer. Nothing seems to break...
1126 3. Fix some compile warnings, prototype all functions.
1128 4. Use glibc err/glob instead of internal compatibility
1129 routines (only if available).
1131 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
1132 by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
1134 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
1135 ======================================================================
1137 1. Integrated the changes from FreeBSD-3.1-RELEASE
1138 (mostly bug fixes, buffer overruns, dump has now an "automatic
1139 tape length calculation" flag, dump/restore can use kerberos now
1140 (this is NOT tested), use environment variables for TAPE and
1143 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
1145 3. Corrected a bug in restore when using 'C' option with multi-volumes
1146 tapes (files splited accros two tapes give "size changed" errors
1149 4. Corrected the long standing bug when dumping multiple tapes.
1150 This works for me, needs further testing.
1152 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
1153 ====================================================================
1155 1. Dump now runs correctly on kernels 2.1.x
1156 Fix made by Gerald Peters <gapeters@worldnet.att.net>
1158 Changes between versions 0.4b2 and 0.4b3
1159 ========================================
1161 1. Use realpath() if available
1163 2. Report statistics
1165 Changes between versions 0.4b1 and 0.4b2
1166 ========================================
1168 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
1171 2. Fixed restore to make it able to read FreeBSD 2.x dumps again
1173 3. Fixed configure.in to correctly handle --enable-rmt
1175 Changes between versions 0.3 and 0.4b1
1176 ======================================
1178 1. Integrated the changes from 4.4BSD-Lite2
1180 2. Integrated the patches from Debian and Red Hat
1182 3. Portability changes: use the __u32, __u16, __s32, and __s16 types
1184 4. Changed dump to use the Ext2fs library to get block addresses. This
1185 should solve the endianness problem on SparcLinux.
1187 5. Created a configure.in file (shamelessly stolen from the e2fsprogs
1188 distribution's one) to use autoconf
1190 6. Fixed a few minor bugs
1192 Changes between versions 0.2e and 0.2f
1193 ======================================
1195 1. Added the creation of named pipes (fifos) in restore.
1197 2. Added the -N flag in the restore manual page.
1199 3. Added the file kernel.patch which contains the llseek() optimization
1200 patch for 1.2.x kernels.
1202 4. Fixed a bug in the restoration of symbolic links: owner and group were
1205 5. Integrated some changes from FreeBSD 2.2.
1207 6. Added a call to ftruncate() after restoring each file to restore
1208 correctly files ending by a hole.
1210 Changes between versions 0.2d and 0.2e
1211 ======================================
1213 1. Fixed a bug in the "set owner/mode" process. Every file was restored
1214 with owner = root (0) and group = root/wheel/whatever (0).
1216 Changes between versions 0.2c and 0.2d
1217 ======================================
1219 1. Dump is now able to backup 2GB+ filesystems.
1221 2. Dump and restore can now be linked as static binaries.
1223 Changes between versions 0.2b and 0.2c
1224 ======================================
1226 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
1228 Changes between versions 0.2a and 0.2b
1229 ======================================
1231 1. Really fixed the bug that I should have corrected in 0.2a.
1233 2. Enabled optimization again.
1235 Changes between versions 0.2 and 0.2a
1236 =====================================
1238 1. Disabled the optimization during compilation.
1240 Changes between versions 0.1 and 0.2
1241 ====================================
1243 1. Fixed a bug in fstab.c which caused a null pointer to be stored in
1244 the fs_type field (actually, I modified the file fstab.c to make it
1245 use the mntent functions).
1247 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups
1248 made by dump should be readable by the BSD restore and backups made
1249 by the BSD dump should be readable by restore. Unfortunately, this
1250 means that the dump format has changed between version 0.1 and version
1253 3. Dump is now able to backup a subtree, it is no longer limited to whole
1254 filesystems like the BSD version.
1256 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger
1259 Changes between versions 0.0 and 0.1
1260 ====================================
1262 1. Now create links rdump and rrestore during the `make install' step.
1264 2. Linux port specific bugs added to the manual pages
1266 3. Incorrect estimation of the number of tapes blocks fixed when doing
1267 incremental backups.
1269 4. Better ls-like format in restore in interactive mode.
