3 Changes between versions 0.4b33 and 0.4b34 (released ?????????????????)
4 =======================================================================
6 1. Fixed the INSTALL file to reflect the actual install paths.
7 Thanks to David Ronis <ronis@ronispc.chem.mcgill.ca> for
10 2. Fixed the configure script to only check for headers presence
11 instead of trying to compile them. This should fix issues
12 with old build environments. Thanks to Kari Lempiainen
13 <kari@funky.pp.fi> for reporting the bug.
15 3. Fixed restore to correctly ignore sockets when comparing
16 a dump (as socket cannot be properly restored anyway). Thanks
17 to Gunther Reiszig <gunther@mit.edu> for reporting the bug.
19 4. Fixed restore to correctly access the archive file (-A argument)
20 even when using a remote tape. Thanks to Fabrice Bellet
21 <fabrice@bellet.info> for reporting the bug.
23 5. Fixed (again) handling of long (largefile) seeks in rmt.
24 Thanks to Fabrice Bellet <fabrice@bellet.info> for reporting
27 6. Fixed restore corner case when dealing with large block sizes
28 dump is able to write now (-b 1024). Thanks to Fabrice Bellet
29 <fabrice@bellet.info> for reporting the bug.
31 7. Fixed a bug preventing dump to access a filesystem having
32 a label exactly 16 bytes in length. Thanks to <minduni@ti-edu.ch>
33 for reporting the bug.
35 8. Made dump store dump dates using explicit timezones, fixing a
36 problem with incremental dumps if the timezone is modified
37 between the dumps. Thanks to Philippe Troin <phil@fifi.org> for
38 the bug report and the patch.
40 9. Fixed a bug encountered when dumping individual files (not full
41 filesystems or directories) and dangling symbolic links happen
42 to be in the list of files. For as far as dump is concerned,
43 dangling symbolic links are allowed, and are dumped as is.
44 Thanks to Jin-su Ahn <jsahn@ee.snu.ac.kr> for reporting the
45 bug and providing the fix.
47 10. Fixed open and creation modes and permissions for QFA and
48 table-of-contents files in dump and restore. Thanks to
49 Philippe Troin <phil@fifi.org> for the patch.
51 11. Fixed the archive file descriptor handling enabling it to be 0.
52 This can happen in some cases when shell redirections are used.
53 Thanks to Philippe Troin <phil@fifi.org> for the patch.
55 12. Delayed the opening of archive file until after suid had been
56 dropped (fixing a possible security issue if dump is suid).
57 Thanks to Philippe Troin <phil@fifi.org> for the patch.
59 13. Fixed the 'S' command handling in the rmt client part.
60 Thanks to Philippe Troin <phil@fifi.org> for the patch.
62 14. Modified the end-of-tape script handling to print out statistics
63 (and stop the timer) before launching the eot script. Also, the eot
64 script does not get run anymore when using -M (which makes sense) or
65 when multiple tapes are listed on the command line
66 (-f tape0,tape1,tapen) (which also makes sense).
67 Thanks to Philippe Troin <phil@fifi.org> for the patch.
69 15. Relicensed dump/restore under the 'revised' BSD license, as per
70 ftp://ftp.cs.berkeley.edu/ucb/4bsd/README.Impt.License.Change.
72 16. Added LZO compression to dump. This new compression method has
73 the advantage of being super fast, thus not killing tape streaming
74 on slow machines. Thanks to Helmut Jarausch
75 <jarausch@igpm.rwth-aachen.de> for the patch and to
76 Markus Oberhumer <markus@oberhumer.com> for giving special permission
77 to include his miniLZO project (GPL licensed) in dump/restore.
79 Changes between versions 0.4b32 and 0.4b33 (released February 10, 2003)
80 =======================================================================
82 1. Added a note in the restore man page clarifying the question
83 'set the permissions on the current directory ?' asked by
84 restore at the end of treatment in -i and -x modes.
86 2. Fixed the endianess issues when reading compressed tapes.
87 Thanks to Dark Force <daq4th@users.sourceforge.net> for
88 reporting this bug and providing test cases.
90 3. Fixed the "ACL won't be dumped" warning message (which showed
91 an extra, unrelated error message). Thanks to Dragan Krnic
92 <dkrnic@lycos.com> for reporting this bug.
94 4. Made dump look first into /etc/mtab, then into /etc/fstab
95 when searching for filesystem paths. Also fixed some problems
96 caused by binding mounts or multiple block device mounts.
97 Thanks to Matus Uhlar <uhlar@fantomas.sk>, Elliott Mitchell
98 <ehem@m5p.com>, Greg Edwards <gedwards@users.sourceforge.net>,
99 Brian Hoy <brian.hoy@opus.co.nz>. (fixes Debian bugs #147086
100 and #160305, Sourceforge bugs #618699 and #679832).
102 5. Made dump's -I option accept the value '0' meaning all the
103 read errors will be ignored. This can be useful when running
104 dump from unattended sessions (like cron jobs). Thanks to
105 John I Wang <jiwang@users.sourceforge.net> for the suggestion.
107 6. Fixed the output of dump to indicate 'blocks' instead of
108 'tape blocks' in the various messages (blocks are always
109 1 Kilobyte, tape blocks are 1 BK * '-b' argument), and
110 made it clearly print the current blocksize at the start of
111 a dump. Thanks to Michal Szymanski <msz@astrouw.edu.pl> for
114 7. Made rmt understand long (largefiles) seeks.
116 8. Fixed build with very old versions of libext2fs, where
117 EXT2_FT_* constants were undefined.
119 9. Made dump accept the dumpdates path on the command line
120 (-D file option) instead of using only the hardcoded one.
121 Thanks to Piete Brooks <pb22@users.sourceforge.net> for the
124 10. Enabled rmt, LFS, readline, QFA options by default in
125 ./configure. Updated the configure process (new versions
126 of config.guess, config.sub etc).
128 Changes between versions 0.4b31 and 0.4b32 (released November 15, 2002)
129 =======================================================================
131 1. Changed dump to use fcntl(F_SETLK) style locking instead
132 of flock() when locking the dumpdates file. With the old
133 locking scheme, a local user having read rights on the
134 dumpdates file could be able to do a Denial of Service attack
135 on dump. In order to lock the dumpdates file with the new
136 scheme, the user would need to have write access on the file.
137 Thanks to Richard Johnson <Richard.Johnson3@ey.com> for
138 reporting the bug (originally a bugtraq post).
140 2. Fixed interactive 'ls' which caused spurious errors warnings
141 about 'undefined filetypes' detected. Thanks to Jorgen Ostling
142 <jorgen_ostling@users.sourceforge.net> for reporting this
145 3. Fixed dump's estimate when dealing with sparse inodes.
147 4. Modified dump to allow setting a blocksize bigger than 32kB
148 (raised the limit to 1024kB), because newer hardware needs
149 this for proper operation. Thanks to Dirk Traenapp
150 <dtraenapp@users.sourceforge.net> for reporting this.
152 5. Fixed a bug causing Dump to stop and report an error if an
153 inode number in the exclude file was followed by some amount
154 of whitespace. Thanks to Jeffrey Sofferin
155 <sofferin@users.sourceforge.net> for reporting this bug.
157 6. Fixed a bug which caused restore, in some particular cases,
158 to ask some 'scary' questions and leave a bunch of RSTTMP
159 directories behind when restoring incremental tapes. Thanks
160 to Philippe Troin <phil@fifi.org> for reporting this bug and
161 providing the test cases.
163 7. Changed the wording when inodes are excluded from dump:
164 replaced 'Added inode 7 to exclude list' with
165 'Excluding inode 7 (resize inode) from dump', as suggested
166 by Elliott Mitchell <ehem@m5p.com> in a Debian bug report.
168 Changes between versions 0.4b30 and 0.4b31 (released July 30, 2002)
169 ===================================================================
171 1. Fixed rmt open flags transmission (GNU's symbolic syntax over
172 rmt) which I broke in 0.4b29. Thanks to Eros Albertazzi
173 <eros@lamel.bo.cnr.it> for reporting the bug.
175 Changes between versions 0.4b29 and 0.4b30 (released July 25, 2002)
176 ===================================================================
178 1. Made dump print out the ext2 logical block number in case of a read
179 error, which can be given as an argument to debugfs' ncheck command,
180 in order to find out the affected inode. Added note about this
181 usage in dump's man page.
183 2. Fixed a problem in restore when reading tapes written on big
184 endian machines with very old versions of dump. The patch was
185 contributed by George Helffrich <george@geology.bristol.ac.uk>.
187 3. Fixed the tape length calculation when using large tapes
188 and compression. Thanks to Georg Lippold
189 <g_lippold@sourceforge.net> for reporting the bug.
191 4. Added a new set of examples in dump_on_cd_2 directory, based
192 on dump_on_cd examples but somewhat enhanced, supporting DVD
193 media, and localized in english and german. Thanks to
194 Georg Lippold <g_lippold@sourceforge.net> for the new scripts.
196 5. Made dump save 32 bit UID/GID. Internally, this was achieved
197 by switching from the old BSD inode format to the new BSD
198 inode format, which means that the tape format was changed.
199 However, since all restore versions out there should
200 transparently support both inode formats, the change should
201 have no side effects. Thanks to John Yu <jky@cs.bu.edu> for
204 6. Fixed a lot of warnings in the code shown when compiling
205 with 'gcc -W'. Thanks to Matthias Andree
206 <matthias.andree@stud.uni-dortmund.de> for reporting this.
208 7. Fixed a small markup bug in the dump man page. Thanks to
209 Eric S. Raymond <esr@minx.thyrsus.com> for submitting the
212 8. Rewrote entirely the man pages using the tmac.an macro
213 package (Linux man page format) instead of the original BSD
214 format. They should be now cleaner and easier to modify.
216 Changes between versions 0.4b28 and 0.4b29 (released June 8, 2002)
217 ==================================================================
219 1. Fixed a problem in the rmt ioctl command, where ioctl's issued from
220 non Linux clients were misinterpreted. The description of the problem
221 (incompatible numbering in Linux mtio opcodes) is documented at
222 ftp://ftp.fokus.gmd.de/pub/unix/star/README.mtio . Thanks to
223 Jörg Schilling <schilling@fokus.gmd.de> for reporting this bug and
224 providing an excellent, cross-platform replacement for rmt in his
227 2. Fixed a bug reported by Andy Mentges <amentges@jumpline.com>
228 which caused restore to fail when the inode maps were not entirely
229 contained on the first volume (when using really small volumes or
230 when dumping a huge number of inodes).
232 3. Fixed a problem in dump, where files in subdirectories of directories
233 that have the nodump flag set (or being excluded with -e/-E) were
234 sometimes incorrectly dumped (instead of being excluded). The original
235 fix is from David C Lawrence <tale@dd.org> in the FreeBSD version
236 of dump: http://www.FreeBSD.org/cgi/query-pr.cgi?pr=32414
237 Thanks to Ted Grzesik <tedgyz@roostme.com> for reporting the bug and
238 help testing the patch.
240 4. Added some example scripts from Gerd Bavendiek <bav@epost.de>
241 which makes one able to pipe the output of dump, by the net, to
242 a remote CD-burner server.
244 5. Made dump use O_CREAT|O_TRUNC both locally and remotely (over rmt),
245 and use GNU's symbolic syntax over rmt instead of numerical values
246 to assure multiple platform compatibility.
248 6. Documented the -d option in restore.
250 7. Added a -v (verbose) mode to dump. For now it just prints the number
251 of the inode being dumped, but this could evolve in future versions
252 to include interesting debugging output.
254 8. Added a -o flag to restore, which automatically restores the current
255 directory permissions in -i or -x mode, without asking the operator
256 whether to do so. Patch submitted by Tony Clayton <tonyc@e-smith.com>
257 and Peter Samuel <peters@e-smith.com>.
259 Changes between versions 0.4b27 and 0.4b28 (released April 12, 2002)
260 ====================================================================
262 1. Fixed a bug in the QFA feature which could have caused
263 a bad tape positionning on restore (causing extra delays in
264 restore). Credits go to Uwe Gohlke <uwe@ugsoft.de>.
266 2. Added a small note in the dump man page specifying that
267 there should be no white space between the option letter and
268 the -j or -z parameter, thanks to Kenneth Porter <shiva@well.com>
270 3. Made restore work with older versions of the readline library,
271 by checking in configure for several extended symbols. Restore
272 can now be compiled with a readline as old as the 2.0 release
273 (though it may be a good idea to upgrade it to a more recent
274 version...). Thanks to Andrew Donkin <ard@waikato.ac.nz> for
275 reporting the build failures.
277 4. Fixed a performance problem with the QFA file creation in
278 dump, which made unnecessary seeks on the tape slowing down
279 the dump. Thanks to Andrew Donkin <ard@waikato.ac.nz> for
280 reporting this issue.
282 5. Removed the inclusion of some kernel headers in the dump
283 source, which prevented the compile in some kernel/glibc
284 headers/architecture combination. Thanks to Bdale Garbee
285 <bdale@gag.com> for reporting the bug.
287 6. Added the appropriate error message when dump fails to
288 open the output file for writing. Thanks to Amith Varghese
289 <amithv@yahoo.com> for reporting this bug.
291 7. Made restore able to understand large Solaris ufsdump tapes
292 (containing inodes bigger than 4194304). Sun have introduced
293 an "extension" to the dump tape format when dealing with
294 those inodes, which was uncorrectly handled by Linux restore.
295 Thanks to Uwe Gohlke <uwe@ugsoft.de> for reporting the bug and
296 providing a test case.
298 8. Added the -m parameter to dump which optimises the output for
299 inodes having been changed but not modified since the last dump
300 ('changed' and 'modified' have the meaning defined in stat(2)).
301 For those inodes, dump will save only the metadata, instead of
302 saving the entire inode contents. Inodes which are either
303 directories or have been modified since the last dump are saved
304 in a regular way. Uses of this flag must be consistent, meaning
305 that either every dump in an incremental dump set have the flag,
308 Changes between versions 0.4b26 and 0.4b27 (released February 15, 2002)
309 =======================================================================
311 1. Fixed behaviour of dump when exceeding resource limits
314 2. Added the -L flag to restore to allow the user to specify a
315 maximal allowed number of miscompares when using restore
316 with the -C option to check the backup.
318 3. Detailed the manual entry for the -N option of restore.
320 4. Added the -a flag to restore to make able doing unattended
321 restores in -i or -x mode (automatically walks through the
322 multiple dump volumes).
324 5. Extended the QFA mode to work with local files and/or
325 remote tapes and files. This way, restore can know in advance
326 the tape number and the offset for the inodes to extract and
327 can minimize the extraction time by seeking directly to the
330 6. Added the -A <archive> option to both dump and restore,
331 which makes dump to archive a dump table-of-contents in
332 the specified file to be used by restore to determine
333 whether a file is in the dump file that is being restored.
334 (the archive file syntax is also compatible with the
335 Solaris ufsdump generated one).
337 7. Small fix in restore making it able to read some (broken ?)
338 Solaris ufsdump tapes.
340 8. Fixed dump to correctly recognise the root filesystem when using
341 ext2 disk labels (LABEL=/). Thanks to John Yu <jky@it.bu.edu>
342 for reporting this bug.
344 9. Added the -P <file> option to restore to create a
345 Quick File Access file from an already made dump. Patch
346 contributed by Uwe Gohlke <uwe@ugsoft.de>.
348 10. Made restore compile and run on Solaris, making it a
349 possible replacement for the standard ufsrestore. Port was
350 contributed by Uwe Gohlke <uwe@ugsoft.de>.
352 Changes between versions 0.4b25 and 0.4b26 (released January 7, 2002)
353 =====================================================================
355 1. Added a set of backup scripts from Eugenio Diaz
356 <getnito@yahoo.com> in the examples section. It features
357 automatic (cron based) full and incremental dumping of
358 several filesystems on a separate filesystem.
360 2. Fixed a off-by-one miscalculation which disabled dumping
361 a one letter subdirectory. Thanks to Chris Siebenmann
362 <cks@utcc.utoronto.ca> for reporting the bug.
364 3. Fixed several restore bugs occuring when trying to
365 restore some missing files on the tape. Thanks to Chris
366 Siebenmann <cks@utcc.utoronto.ca> for reporting the bug.
368 4. Fixed --with-ldopts configure argument passing, installing from
369 a separate object directory, makefile cleanups contributed
370 by <splite@purdue.edu>.
372 5. Fix a bug which could caused, in some conditions, the highest
373 number inode of a filesystem, to not be dumped. Many thanks
374 to Chris Siebenmann <cks@utcc.utoronto.ca> for helping me
377 Changes between versions 0.4b24 and 0.4b25 (released November 17, 2001)
378 =======================================================================
380 1. Added a mini howto from Patrick Walsh in the examples
383 2. Minor man pages syntax corrections. Thanks to
384 Chris Danis <screechco@home.com> for reporting the bugs.
386 3. Added a script from David B. Peterson <dave@toppledwagon.com>
387 to the examples section. It features dumping several
388 filesystems to a remote tape drive upon ssh.
390 4. Added a patch provided by Richard Jones <rich@annexia.org>
391 which allows BRADEMAX (number of read errors tolerated by
392 dump) to be adjusted using the -I option.
394 5. Fixed a bug which disabled doing "restore -C -f -". Thanks
395 to Clemens Stiglechner <a9401816@unet.univie.ac.at> for the
398 6. Add the -l option to restore to specify if, when doing a
399 remote restore, the file used to access the backup is a
400 regular file (the defaults being a tape drive). Restore needs
401 to know this information when reading a remote compressed
402 dump. Previously, this information was autodetected, but
403 the autodetection code fails (with ioctl: Inappropriate ioctl
404 for device) when using a non Linux remote box. Thanks to
405 many users and especially to Eros Albertazzi
406 <eros@lamel.bo.cnr.it> for reporting this.
408 7. Found a workaroung for the dump deadlock problem (3 childs
409 stuck in pause(), father in read()). The workaround seems
410 to work for me and several beta-testers. If it doesn't work
411 for you, please report back.
413 8. Updated the RPM spec file (BuildPrereq, URL etc).
415 Changes between versions 0.4b23 and 0.4b24 (released September 12, 2001)
416 ========================================================================
418 1. Fixed the permissions of a newly created QFA file by dump.
420 2. Cleaned up the source of dump (the external variables
421 definition was a complete mess, making possible to have
424 3. Fixed restore to use the full tape volume path when doing
425 a compare (since it changes the working directory to the
426 filesystem being compared in the process).
428 4. Added the -q option to dump which makes dump abort
429 whenever it needs operator attention. It should be
430 easier to use dump in scripts with this option.
432 5. Detect the use of incompatible options to dump and
433 refuse them (like -a and -B options together).
435 6. Added bzip2 compression to dump/restore (use option -j level
436 to select it). Note that you will need a restore version
437 >= 0.4b24 in order to restore a bzip2 compressed dump.
438 The same warning as for the zlib compression applies:
439 the tape format of a bzip2 dump is not compatible with the
440 original BSD tape format.
442 7. Fixed a overflow problem in dump corrupting the dump when
443 very large files were encountered. Thanks to Vladimir Nadvornik
446 8. Added a ioctl(BLKFLSBUF) in dump which should flush the
447 kernel buffer/page cache before starting the dump, helping
448 a bit those who use dump on mounted filesystems. Thanks to
449 John Yu <jky@it.bu.edu> and to Theodore T'so <tytso@mit.edu>
452 9. Updated the RPM spec file following the RedHat changes
453 (dynamically linked binaries now in /usr/sbin etc).
455 10. Added a patch from Helmut Jarausch <jarausch@igpm.rwth-aachen.de>
456 which enables restore to recognise multi volume compressed dumps
457 done on CD. Included his scripts for dump (which pipe the dump
458 output directly into cdrecord) and restore. There is now
459 possible to to backups to CD on the fly!
461 Changes between versions 0.4b22 and 0.4b23 (released July 20, 2001)
462 ===================================================================
464 1. Fixed a buffer overflow in restore/tape.c. Patch provided by
465 Marcus Meissner (Caldera International Security Dept.).
467 2. Implement the Sun rmt extended protocol. Patch submitted
468 by Ian Gordon <iangordon@users.sourceforge.net>.
470 3. Check for the e2fsprogs header <ext2fs/ext2_fs.h> instead of
471 the linux kernel header. This ensures that dump always has the
472 latest version of this file. Patch submitted by
473 Andreas Dilger <adilger@turbolinux.com>.
475 4. Report any filesystem present in either /etc/fstab with a
476 positive passno or /etc/dumpdates in dump -w output.
477 Patch submitted by Andreas Dilger <adilger@turbolinux.com>.
479 5. Fixed the looping problem in dump introduced in the
482 6. Changed the -B option of dump to limit the size of
483 _compressed_ output per volume if compression is on.
484 Patch contributed by Helmut Jarausch
485 <jarausch@igpm.rwth-aachen.de>. Note however that, since
486 it is impossible to predict the size of the compressed
487 data before doing the compression, the -B limit is a bit
490 7. Fixed a bug in reading the operator typed file/tape path for
491 the next volume in restore.
493 8. Implemented a "-F script" option to restore which permits the
494 user to specify a script which will be launched at the
495 beginning of each tape, useful for automatic programming of
496 tape changers for example. See the restore man page for the
497 script parameters and return codes.
499 9. Small fix for the QFA routines provided by Uwe Gohlke
500 <uwe@ugsoft.de>, and some recommendations for QFA uses in
503 10. Fixed the multivolume restoring where making a mistake
504 to the 'Mount next tape' prompt caused several blocks to
507 11. Enhanced the -e option of dump to take as a parameter a
508 comma separated list of inode numbers.
510 12. Added the -E option to dump which specify a file containing
511 inode numbers to exclude from the dump.
513 13. Fixed the compressed multi-volume dump + restore.
515 Changes between versions 0.4b21 and 0.4b22 (released May 12, 2001)
516 ==================================================================
518 1. Made dump report the number of blocks dumped per volume.
519 Thanks to Kenneth Porter <shiva@well.com> for the suggestion.
521 2. Fix a bug in dump where waiting too much at the 'change volumes'
522 question caused the volume to be rewritten. Thanks to
523 Graham Reed <greed@users.sourceforge.net> for reporting the
524 bug and providing a patch.
526 3. Added a compression option to dump, contributed by Jerry
527 Peters <gapeters@worldnet.att.net>.
529 WARNING: the compression works only on files/pipes and
530 drives supporting variable block size.
532 WARNING2: tapes created using the compression feature are
533 incompatible with the standard dump tape format, and a
534 version of restore >= 0.4b22 will be needed for extraction.
536 4. Fixed some compilation problems for glibc 2.2.2 and 64 bit
537 architectures. Thanks to Paul Slootman <paul@debian.org> for
538 the patch and to Bdale Garbee <bdale@gag.com> for forwarding
541 5. Many cleanups (CPP defines, const char warnings, check of
542 ext2fs COMPAT flags, time_t cleanups, added libext2 version
543 in dump usage text) by Andreas Dilger <adilger@turbolinux.com>.
545 6. Made --prefix option work in configure. All the install path
546 are now based on the configure parameters.
548 7. Added the Quick File Access mode in dump/restore, contributed
549 by Uwe Gohlke <uwe@ugsoft.de>. In this mode, dump stores in
550 a file tape position for each inode, and this file is used by
551 restore (if called with parameter Q and the filename)
552 to directly position the tape at the file restore is currently
553 working on. This saves hours when restoring single files from
554 large backups, saves the tapes and the drive's head. Use
555 --enable-qfa option of configure to compile in the QFA support.
557 8. Added the possibility to dump several files and directories
558 in a single invocation of dump. Thanks to Uwe Gohlke
559 <uwe@ugsoft.de> for implementing this option.
561 9. Fixed the dumping and restoring of files with holes
562 (files ending with holes didn't get dumped or restored
565 10. Fixed a socket descriptor leak in dump, which leaved opened
566 3 file descriptors per dump process (and there is one dump
569 11. Fixed dump large file system support, by explicit use of
570 open64/lseek64/etc functions (explicit use needed because
571 e2fsprogs libraries don't behave well when compiled with
572 FILE_OFFSET_BITS=64).
574 Changes between versions 0.4b20 and 0.4b21 (released January 13, 2001)
575 ======================================================================
577 1. Fixed some bugs in the dump -w|-W logic introduced by
578 the previous version. Thanks to Andreas Dilger
579 <adilger@turbolinux.com> for his help on this one.
581 2. Fixed again a compilation problem when using old e2fs
582 headers (filesystem label related). Thanks to many users
583 who reported this stupid error.
585 3. Fixed a build problem on old lib5 based systems dealing with
586 _PATH_MNTTAB being undefined. Thanks to John Adams
587 <johna@onevista.com> for reporting the bug.
589 4. Improved the error detection in restore when creating
590 the temporary files in TMPDIR. Now restore will corectly
591 report a 'no space left on device' error instead of
592 strange errors which could imply an archive corruption.
593 Thanks to Gabriel Somlo <somlo@cs.colostate.edu> and
594 bgjenero <bgjenero@sympatico.ca> for reporting the bug.
596 5. Added the throughput information in dump's progression
597 messages. Thanks to Andreas Dilger <adilger@turbolinux.com>
600 6. Use libext2fs's inode scanning routines, which are particularly
601 robust when dealing with errors (especially when having some
602 bad blocks on the filesystem). Many thanks to Colin
603 <colin@horizon.com> for reporting the bug, investigating
604 the issues, finding a workaround, writing the patch and
605 fully testing it... (of course, if this patch will break
606 anything, he is to blame for :-)).
608 7. Made dump and restore LFS aware. Dump can dump a filesystem
609 containing large files, generate a large file on output and
610 restore can restore them. This feature is not enabled by
611 default, use --enable-largefile option of configure to enable
612 it (you need to have a LFS aware glibc though). Thanks to
613 Andrea Arcangeli <andrea@suse.de> for submitting the patch,
614 and to Theodore T'so <tytso@valinux.com> for his always
617 8. Made dump ask upon a tape write error if it should rewrite
618 the current volume (assume this is a bad tape) or if it should
619 assume an end-of-tape condition (useful for tape drives which
620 behaves badly at the end of the tape). Thanks to Andreas
621 Dilger <adilger@turbolinux.com> for the suggestion.
623 Changes between versions 0.4b19 and 0.4b20 (released November 10, 2000)
624 =======================================================================
626 1. Fixed a small compilation problem due to a change
627 in the definintion of the struct sigaction in
628 glibc 2.0 / libc5. Thanks to Gunther Schlegel
629 <schlegel@riege.de> for reporting the bug and to
630 Dave Platt <dplatt@snulbug.mtview.ca.us> for suggesting
633 2. Modified the label and uuid analysis in order to be
634 self-contained (independant of kernel/libc headers). This
635 should fix the compile with older kernel/libc headers and
636 will preserve the functionality. Thanks to Bernhard Erdmann
637 <bernhard.erdmann@gmx.de> for reporting the bug.
639 3. The 'exclude inode' option, if applied to a directory
640 inode, excludes now correctly all the leaves of this
641 directory. Thanks to John R. Dennison
642 <gerdesas@users.sourceforge.net> for reporting the bug.
644 4. Fixed the '-e' option to disable the possibility
645 to exclude the root inode (which causes the dumps to
646 be unreadable by restore). Prevented array overflow
647 when multiple -e options are used.
649 5. Fixed dump to correctly interpret a filesystem argument
650 which is a mountpoint and it is not an absolute path
651 (as specified in the fstab). Thanks to Bernhard R. Erdmann
652 <be@berdmann.de> for reporting the bug.
654 6. Made dump able to backup files larger than 2 GB. Note that
655 dump still doesn't cope with files larger than 4 GB.
657 7. Restore the real uid and gid before invoking an external
658 RSH program (big hole when dump or restore is suid root!).
660 8. Get the values for the default tape device and the location
661 of fstab file from the system headers. Thanks to
662 Andreas Dilger <adilger@turbolinux.com> for the patch.
664 9. Made dump -w|-W report all recognized filesystems
665 present in either /etc/fstab or /etc/dumpdates, and present
666 the list in the same order as in fstab file. Thanks
667 to Andreas Dilger <adilger@turbolinux.com> for the patch.
669 10. Made dump's -a (automatic end of tape detection) the
670 default. Specifying one of -B, -c, -d or -s options will
671 override the EOM detection. Thanks to Andreas Dilger
672 <adilger@turbolinux.com> for the patch.
674 11. Save the ext2 filesystem label into the dump volume label.
675 Specifying a volume label on the command line (-L option)
676 will override this feature. Thanks to Andreas Dilger
677 <adilger@turbolinux.com> for the patch.
679 Changes between versions 0.4b18 and 0.4b19 (released August 20, 2000)
680 =====================================================================
682 1. Fixed the signal handling in dump (which I broke in 0.4b17)
683 which was causing several strange dump failures (dump
684 hanged or segmentation faults etc).
686 2. Specified the default blocksize in the dump man page.
688 3. Changed two info messages of restore to be written on stdout
689 instead of stderr in order to leave stderr only for errors
690 or warnings. Thanks to Stephen Atwell
691 <satwell@urbana.css.mot.com> for the suggestion.
693 4. Corrected an off by one calculation which prevented
694 dumping a directory having a 1 character name length.
695 Thanks to Bernhard Erdmann <bernhard.erdmann@gmx.de>
696 for reporting the bug.
698 5. Reinforce dump in order to allow only level 0 and no
699 -u option when dumping a subdirectory, and document
700 this in the man page. Thanks to Bernhard Erdmann
701 <bernhard.erdmann@gmx.de> for reporting the bug.
703 6. Fixed a small harmless bug in restore which caused
704 in some conditions hard links to be restored several
705 times (therefore generation some warning messages).
706 Thanks to Kenneth Porter <shiva@well.com> for
709 7. Updated the RPM spec file to the latest RedHat version,
710 providing FHS packaging and other cosmetic changes.
711 You will need RPM version >= 3.0.5 in order to build the RPM.
713 8. Updated the configure script to check for libtermcap
714 before checking for libreadline, because we need this
715 library in order to compile the readline support.
717 9. Made dump understand the LABEL= and UUID= notation
718 both in /etc/fstab and on the command line. Note that
719 you will need the /proc filesystem in order to use
720 these notations. Thanks to Erik Troan <ewt@redhat.com>
721 for providing the patch.
723 Changes between versions 0.4b17 and 0.4b18 (released June 30, 2000)
724 ===================================================================
726 1. Fixed a potential buffer overflow in restore. Thanks
727 to Stan Bubrouski <satan@fastdial.net> for reporting
730 2. Fixed a readline-related bug which prevented
731 'cat DUMPFILE | restore -i -f -' from working. Thanks
732 to Charles Karney <karney@users.sourceforge.net>
735 3. Changed a few "panic" into "exit", causing restore to
736 be more stable against some attacks (like the last one
737 reported on Bugtraq, although the last version of restore
738 was not vulnerable - just dumped core). Thanks to
739 Andreas Hasenack <andreas@conectiva.com.br> for reporting
742 4. Removed the suid-root bit on dump and restore in the
743 default build (and generated RPMs). It should be safer
744 now. Users who need the suid-root capabilities in order
745 to make network backups should read first the man page
746 of dump and enable the suid bit manually.
748 5. Added -ltermcap to the compile parameters for restore
749 when using readline support, in order to make the compile
750 process work on some systems (SuSE ?). Thanks to
751 Patrik Schindler <poc@pocnet.net> for reporting the bug.
753 Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000)
754 ====================================================================
756 1. The -F script is called now *only* at the end of a tape,
757 not at the end of the dump. Thanks to Christian Haul
758 <haul@informatik.tu-darmstadt.de> for the bug report.
760 Normally, the device name and the current volume number
761 are passed on the command line of the script. However,
762 if you want the old style script (with no arguments
763 passed on the command line), you can enable it in
764 configure with the --enable-oldstylefscript.
766 2. Use posix signal handling to preserve dump functionality
767 with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for
770 3. Made the exit code of restore in case of a 'C'ompare
771 command reflect the result of the compare. An exit status
772 of 0 means the dump archive is correct, 1 means tape errors,
773 2 means that some files were modified. Thanks to Kenneth Porter
774 <shiva@well.com> for the suggestion.
776 4. Made (finally) quotes work in interactive restore.
778 5. Small fixes in order to allow dump to compile with a
779 really old e2fsprogs version. Thanks to Ian Zimmerman
780 <itz@speakeasy.org> for the bug report.
782 6. Add GNU readline capabilities to interactive restore.
783 Use configure's --enable-readline flag to enable this feature.
784 Thanks to Patrik Schindler <poc@pocnet.net> for the
787 7. Do the compare on the fly in restore 'C' mode (this will
788 allow not to exhaust the available /tmp space when
789 ccmparing large files). Thanks to Kenneth Porter
790 <shiva@well.com> for the suggestion.
792 Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000)
793 ====================================================================
795 1. Fixed some several duplicate 'DUMP: DUMP:' in the
798 2. Corrected the estimation of blocks to dump. Note that
799 this is still wrong for large directory inodes, due
800 to the size of a BSD directory entry on the tape
801 (estimation is based on the size of the ext2 directory,
802 which is smaller because it doesn't contain the null
803 character at the end).
805 3. Made dump report the total number of MB written to
806 tape at the end of run. Thanks to W. Reilly Cooley
807 <wcooley@nakedape.cc> for the patch.
809 4. Added the -X option to restore giving the possibility
810 to read the names of the files to be extracted/listed
811 from a text file (in addition of the command line).
812 Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the
815 5. Added the device name and the current volume number
816 as arguments to the end of tape script (dump -F option).
818 6. Made the multi-volume dump work again (after having
819 broken it in 0.4b15).
821 Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000)
822 ===================================================================
824 1. Added a prompt command in interactive restore mode. Thanks
825 to Andreas Dilger <adilger@home.com> for the patch.
827 2. Fixed a buffer overflow problem in dump (caused by
828 not checking the size of the filesystem parameter).
829 Thanks to Kim Yong-jun <loveyou@hackerslab.org> for
830 reporting this on Bugtraq (and to several dump users
831 who forwarded me his mail).
833 3. Added the '-F script' option to dump in order to
834 launch a script at the end of each tape (to be used
835 with a tape changer, or to notify the sysadmin by
838 4. Fixed a bug in restore compare code caused by the changes
841 5. Fixed the treatment of options using the old BSD syntax
842 in both dump and restore.
844 Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000)
845 =======================================================================
847 1. Fixed a bug in dump which may have caused invalid deleted
848 directories to be dumped out if they were deleted after the
849 mapping pass. This could occure on active filesystem and lead
850 to heap corruption (causing dump malfunction in many possible ways).
851 Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this
852 bug and submitting the patch.
854 2. Fixed the handling of the filesystem parameter in dump. A
855 '/mnt/disk' parameter caused the disk contents to be dumped,
856 but a '/mnt/disk/' parameter caused the mountpoint directory
857 to be dumped (generally an empty directory).
859 3. Improved the output of dump in order to tell which directory
860 it is currently dumping (when dumping a subtree).
862 4. Added the '-e' exclude inode option to dump. Thanks to
863 Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch.
865 5. Added a REPORTING-BUGS file in order to provide a guide
866 on how to correctly report a bug in dump/restore.
868 6. Fixed a restore problem when restoring a hard link to an inode
869 having the immutable or append-only attribute set. Thanks to
870 Ambrose Li <acli@mingpaoxpress.com> for submitting the patch.
872 7. Fixed a compatibility problem between dumps made on little
873 endian machines (the format was correct) and big endian
874 machines (the format was incorrect). This fix break the
875 compatibility with the older dumps made on big endian
876 machines (sparc, m86k, ppc etc). For the first time in
877 linux dump's history (I believe), the dumps made by *BSD,
878 Linux/alpha, Linux/sparc and Linux/x86 are compatible,
879 so interchangeable. Thanks to Rob Cermak
880 <cermak@ahab.rutgers.edu> for submitting the bug and
881 helping me test the fix.
883 8. Fixed the way dump reports the remaining percent/time, if
884 the number of blocks actually dumped exceeds the estimated
885 number of blocks. Thanks to Jean-Paul van der Jagt
886 <jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug.
888 Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000)
889 ======================================================================
891 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski
892 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug.
894 2. Removed the requirement to build the RPM as root from the
895 spec file. Thanks to Christian Weisgerber
896 <naddy@mips.rhein-neckar.de> for submitting this.
898 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs,
899 causing dump to block when dumping really huge filesystems.
900 Many thanks to Patrik Schindler <poc@pocnet.net> for
901 helping me find this bug.
903 4. Fixed the treatment for an interrupt signal when dump access
904 the remote tape through RSH. Thanks to Christian Weisgerber
905 <naddy@mips.rhein-neckar.de> for providing the patch.
907 5. Fixed a bug which was causing dump/restore to display
908 garbage characters instead of the remote host name.
910 Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000)
911 =====================================================================
913 1. Small fix in the dump man page. Thanks to Thorsten Kukuk
914 <kukuk@suse.de> for submitting the patch.
916 2. Fix for the exit code when using the size estimate option of
917 dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for
918 submitting the patch.
920 3. Handle EINTR in atomical reads/writes in dump, which was causing
921 dump to fail on some systems. Thanks to Eric Jergensen
922 <eric@dvns.com> for reporting the bug and submitting the patch.
924 4. Handle more than 16 characters for the device names in dumpdates.
925 (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for
926 tracking down the problem and proposing the solution.
928 5. Fixed a bug in dump which prevented the creation of the
929 dumpdates file when doing a 0-level dump without already
930 having a dumpdates file. Thanks to Patrik Schindler
931 <poc@pocnet.net> for reporting the bug.
933 6. Changed the way dump 'S' flag reports the size estimate
934 from number of blocks into bytes (making it compatible
935 with the Solaris version, and simplifying things for
936 amanda users). Thanks to Jason L Tibbitts III
937 <tibbs@math.uh.edu> for reporting the bug.
939 7. Fixed a compatibility problem in linux/alpha dump tape format.
940 Now the linux/alpha dump are (again) compatible with the
941 other dump formats. But this breaks compatibility with
942 older dumps made on alpha. Thanks to Mike Tibor
943 <tibor@lib.uaa.alaska.edu> for helping me in finding this bug.
945 Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
946 ======================================================================
948 1. Added a '--enable-kerberos' to configure.
950 2. Added a 'S' option to dump which determines the amount of space
951 that is needed to perform the dump without actually doing it, similar
952 to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
953 <cermak@ahab.rutgers.edu>.
955 3. Added a 'M' multi-volume option to dump and restore which enables
956 dumping to multiple files (useful when dumping to an ext2
957 partition to make several dump files in order to bypass the 2GB
958 file size limitation). The 'f' argument is treated as a prefix and
959 the output files will be named <prefix>001, <prefix>002 etc. With
960 the 'M' flag, restore automatically selects the right file without
961 asking to enter a new tape each time.
963 4. Fixed a memory leak which was causing dump to grow very big
964 (270MB when dumping a 10GB filesystem...). Thanks to Jason
965 Fearon <jasonf@netrider.org.au> for reporting the bug.
967 Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
968 ======================================================================
970 1. Make configure test if the system glob routines support
971 extended syntax (ALTDIRFUNC). If not, use the internal glob
972 routines instead of system ones. Thanks to Bernhard Sadlowski
973 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
974 and helping me resolve this and other minor libc5 compiling
977 2. Fix a problem when dumping a ext2fs with the 'filetype'
978 feature enabled. Thanks to Patrick J. LoPresti
979 <patl@cag.lcs.mit.edu> for reporting the bug and to
980 Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.
982 3. Made the nodump flag work on directories. A directory which
983 has the nodump flag gets never dumped, regardless of its
986 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
987 which allows dump on an active ext3 filesystem. However, this
988 is a "quick and dirty" patch which enables backup of an ext3
989 filesystem through the ext2 compatibility (by ignoring the
990 NEEDS_RECOVERY bit). The journal file is not recognized and
991 it is dumped (it should not).
993 5. Test the superblock compatibility flags when dumping, in order
994 to be sure that we know how to deal with specific features.
996 Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
997 ====================================================================
999 1. Use lchown instead of chown, fixing a possible security problem
1000 when restoring symlinks (a malicious user could use this
1001 to deliberately corrupt the ownership of important system files).
1002 Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
1003 this and providing the patch.
1005 Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
1006 ====================================================================
1008 1. Put dump sources under CVS, added Id tags in all files so
1009 one can use 'ident' on binary files.
1011 2. Added the dump/restore version in the usage text so one can
1012 easily verify the version he is using.
1014 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
1015 a va_start/va_end problem on linux-ppc (always call va_start
1016 va_end in pairs each time we use a vararg function).
1018 4. Added again the DT_* constants because old libc does not
1019 contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
1020 for submitting the bug report.
1022 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs
1023 this should enable dumping big (huge) filesystems.
1025 6. Added the RSH environment variable in order to be able to
1026 use a rsh replacement like ssh when doing remote backups (and
1027 bypass the security limitations of rcmd). Now you can do remote
1028 backups without being root (or making dump setuid root).
1030 7. Modified again the way dumpdates works. For incremental dumps,
1031 we need to read dumpdates even if we are not using 'u' option.
1032 Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
1035 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
1036 ===================================================================
1038 1. Removed the 'k' flag from the restore 'about' text if kerberos
1039 was not compiled in.
1041 2. Prototyped (f)setflags from e2fsprogs and corrected the calls
1042 to them (fsetflags takes a char*, setflags an open fd!).
1044 3. (f)setflags is called only if the flags aren't empty. If the
1045 file is a special file, a warning is printed, because changing
1046 flags implies opening the device. Normally, a special file
1047 should not have any flag... (Debian bug #29775, patch provided
1048 by Abhijit Dasgupta <abhijit@ans.net>).
1050 4. Made possible to dump a file system not mentioned in /etc/fstab.
1051 (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
1053 5. Changed the default behaviour to not create dumpdates
1054 unless 'u' option is specified. Removed the old "debian-patch"
1055 which provided the same thing. (Debian bug #38136, #33818).
1057 6. Removed all those dump*announce, since they were getting old...
1059 7. Added warning messages if dumpdates does not exist and
1060 when an inferior level dump does not exist (except for a level 0
1063 8. Debugged the glob calls in interactive mode: restore used a
1064 dirent struct which was different from the /usr/include/dirent.h
1065 one (this used to work, is it a glibc2 change?), so none of the
1066 compat glob (which used /usr/include/dirent.h) or the system glob
1067 worked. Restore use now the system dirent (and the system
1068 DT_* constants), which are compatible with BSD ones.
1070 9. Added a configure flag (--with-dumpdatespath) to specify
1071 the location of dumpdates file. By default, it is
1074 10. Added the "AUTHOR" and "AVAILABILITY" sections and
1075 included the current date/version in man pages.
1077 11. Corrected the estimation of remaining time when
1078 the operator doesn't change the tapes quickly enough. This
1079 was an old bug, I thought I corrected it, and discovered
1080 that in fact it was corrected in two different places, so
1081 the results canceled each other...
1083 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
1084 ===================================================================
1086 1. Integrated multiple patches from RedHat, Debian and SuSE:
1088 - tweak dump/itime.c to not try to read dumpdates if the 'u' option
1090 - several fixes in the man pages.
1091 - update the default tape device to /dev/st0.
1092 - many updates for Linux Alpha (byte ordering, size_t etc).
1094 - use environment variable for TMPDIR (instead of /tmp).
1095 - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
1096 - workaround egcs bug (RedHat bugs #4281 and #2989).
1097 - wire $(OPT) throughout Makefile's.
1099 2. Upgrade the dump revision to 1, making possible to dump filesystems
1100 made with e2fsprogs-1.15 or newer. Nothing seems to break...
1102 3. Fix some compile warnings, prototype all functions.
1104 4. Use glibc err/glob instead of internal compatibility
1105 routines (only if available).
1107 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
1108 by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
1110 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
1111 ======================================================================
1113 1. Integrated the changes from FreeBSD-3.1-RELEASE
1114 (mostly bug fixes, buffer overruns, dump has now an "automatic
1115 tape length calculation" flag, dump/restore can use kerberos now
1116 (this is NOT tested), use environment variables for TAPE and
1119 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
1121 3. Corrected a bug in restore when using 'C' option with multi-volumes
1122 tapes (files splited accros two tapes give "size changed" errors
1125 4. Corrected the long standing bug when dumping multiple tapes.
1126 This works for me, needs further testing.
1128 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
1129 ====================================================================
1131 1. Dump now runs correctly on kernels 2.1.x
1132 Fix made by Gerald Peters <gapeters@worldnet.att.net>
1134 Changes between versions 0.4b2 and 0.4b3
1135 ========================================
1137 1. Use realpath() if available
1139 2. Report statistics
1141 Changes between versions 0.4b1 and 0.4b2
1142 ========================================
1144 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
1147 2. Fixed restore to make it able to read FreeBSD 2.x dumps again
1149 3. Fixed configure.in to correctly handle --enable-rmt
1151 Changes between versions 0.3 and 0.4b1
1152 ======================================
1154 1. Integrated the changes from 4.4BSD-Lite2
1156 2. Integrated the patches from Debian and Red Hat
1158 3. Portability changes: use the __u32, __u16, __s32, and __s16 types
1160 4. Changed dump to use the Ext2fs library to get block addresses. This
1161 should solve the endianness problem on SparcLinux.
1163 5. Created a configure.in file (shamelessly stolen from the e2fsprogs
1164 distribution's one) to use autoconf
1166 6. Fixed a few minor bugs
1168 Changes between versions 0.2e and 0.2f
1169 ======================================
1171 1. Added the creation of named pipes (fifos) in restore.
1173 2. Added the -N flag in the restore manual page.
1175 3. Added the file kernel.patch which contains the llseek() optimization
1176 patch for 1.2.x kernels.
1178 4. Fixed a bug in the restoration of symbolic links: owner and group were
1181 5. Integrated some changes from FreeBSD 2.2.
1183 6. Added a call to ftruncate() after restoring each file to restore
1184 correctly files ending by a hole.
1186 Changes between versions 0.2d and 0.2e
1187 ======================================
1189 1. Fixed a bug in the "set owner/mode" process. Every file was restored
1190 with owner = root (0) and group = root/wheel/whatever (0).
1192 Changes between versions 0.2c and 0.2d
1193 ======================================
1195 1. Dump is now able to backup 2GB+ filesystems.
1197 2. Dump and restore can now be linked as static binaries.
1199 Changes between versions 0.2b and 0.2c
1200 ======================================
1202 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
1204 Changes between versions 0.2a and 0.2b
1205 ======================================
1207 1. Really fixed the bug that I should have corrected in 0.2a.
1209 2. Enabled optimization again.
1211 Changes between versions 0.2 and 0.2a
1212 =====================================
1214 1. Disabled the optimization during compilation.
1216 Changes between versions 0.1 and 0.2
1217 ====================================
1219 1. Fixed a bug in fstab.c which caused a null pointer to be stored in
1220 the fs_type field (actually, I modified the file fstab.c to make it
1221 use the mntent functions).
1223 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups
1224 made by dump should be readable by the BSD restore and backups made
1225 by the BSD dump should be readable by restore. Unfortunately, this
1226 means that the dump format has changed between version 0.1 and version
1229 3. Dump is now able to backup a subtree, it is no longer limited to whole
1230 filesystems like the BSD version.
1232 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger
1235 Changes between versions 0.0 and 0.1
1236 ====================================
1238 1. Now create links rdump and rrestore during the `make install' step.
1240 2. Linux port specific bugs added to the manual pages
1242 3. Incorrect estimation of the number of tapes blocks fixed when doing
1243 incremental backups.
1245 4. Better ls-like format in restore in interactive mode.
