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 Changes between versions 0.4b32 and 0.4b33 (released February 10, 2003)
73 =======================================================================
75 1. Added a note in the restore man page clarifying the question
76 'set the permissions on the current directory ?' asked by
77 restore at the end of treatment in -i and -x modes.
79 2. Fixed the endianess issues when reading compressed tapes.
80 Thanks to Dark Force <daq4th@users.sourceforge.net> for
81 reporting this bug and providing test cases.
83 3. Fixed the "ACL won't be dumped" warning message (which showed
84 an extra, unrelated error message). Thanks to Dragan Krnic
85 <dkrnic@lycos.com> for reporting this bug.
87 4. Made dump look first into /etc/mtab, then into /etc/fstab
88 when searching for filesystem paths. Also fixed some problems
89 caused by binding mounts or multiple block device mounts.
90 Thanks to Matus Uhlar <uhlar@fantomas.sk>, Elliott Mitchell
91 <ehem@m5p.com>, Greg Edwards <gedwards@users.sourceforge.net>,
92 Brian Hoy <brian.hoy@opus.co.nz>. (fixes Debian bugs #147086
93 and #160305, Sourceforge bugs #618699 and #679832).
95 5. Made dump's -I option accept the value '0' meaning all the
96 read errors will be ignored. This can be useful when running
97 dump from unattended sessions (like cron jobs). Thanks to
98 John I Wang <jiwang@users.sourceforge.net> for the suggestion.
100 6. Fixed the output of dump to indicate 'blocks' instead of
101 'tape blocks' in the various messages (blocks are always
102 1 Kilobyte, tape blocks are 1 BK * '-b' argument), and
103 made it clearly print the current blocksize at the start of
104 a dump. Thanks to Michal Szymanski <msz@astrouw.edu.pl> for
107 7. Made rmt understand long (largefiles) seeks.
109 8. Fixed build with very old versions of libext2fs, where
110 EXT2_FT_* constants were undefined.
112 9. Made dump accept the dumpdates path on the command line
113 (-D file option) instead of using only the hardcoded one.
114 Thanks to Piete Brooks <pb22@users.sourceforge.net> for the
117 10. Enabled rmt, LFS, readline, QFA options by default in
118 ./configure. Updated the configure process (new versions
119 of config.guess, config.sub etc).
121 Changes between versions 0.4b31 and 0.4b32 (released November 15, 2002)
122 =======================================================================
124 1. Changed dump to use fcntl(F_SETLK) style locking instead
125 of flock() when locking the dumpdates file. With the old
126 locking scheme, a local user having read rights on the
127 dumpdates file could be able to do a Denial of Service attack
128 on dump. In order to lock the dumpdates file with the new
129 scheme, the user would need to have write access on the file.
130 Thanks to Richard Johnson <Richard.Johnson3@ey.com> for
131 reporting the bug (originally a bugtraq post).
133 2. Fixed interactive 'ls' which caused spurious errors warnings
134 about 'undefined filetypes' detected. Thanks to Jorgen Ostling
135 <jorgen_ostling@users.sourceforge.net> for reporting this
138 3. Fixed dump's estimate when dealing with sparse inodes.
140 4. Modified dump to allow setting a blocksize bigger than 32kB
141 (raised the limit to 1024kB), because newer hardware needs
142 this for proper operation. Thanks to Dirk Traenapp
143 <dtraenapp@users.sourceforge.net> for reporting this.
145 5. Fixed a bug causing Dump to stop and report an error if an
146 inode number in the exclude file was followed by some amount
147 of whitespace. Thanks to Jeffrey Sofferin
148 <sofferin@users.sourceforge.net> for reporting this bug.
150 6. Fixed a bug which caused restore, in some particular cases,
151 to ask some 'scary' questions and leave a bunch of RSTTMP
152 directories behind when restoring incremental tapes. Thanks
153 to Philippe Troin <phil@fifi.org> for reporting this bug and
154 providing the test cases.
156 7. Changed the wording when inodes are excluded from dump:
157 replaced 'Added inode 7 to exclude list' with
158 'Excluding inode 7 (resize inode) from dump', as suggested
159 by Elliott Mitchell <ehem@m5p.com> in a Debian bug report.
161 Changes between versions 0.4b30 and 0.4b31 (released July 30, 2002)
162 ===================================================================
164 1. Fixed rmt open flags transmission (GNU's symbolic syntax over
165 rmt) which I broke in 0.4b29. Thanks to Eros Albertazzi
166 <eros@lamel.bo.cnr.it> for reporting the bug.
168 Changes between versions 0.4b29 and 0.4b30 (released July 25, 2002)
169 ===================================================================
171 1. Made dump print out the ext2 logical block number in case of a read
172 error, which can be given as an argument to debugfs' ncheck command,
173 in order to find out the affected inode. Added note about this
174 usage in dump's man page.
176 2. Fixed a problem in restore when reading tapes written on big
177 endian machines with very old versions of dump. The patch was
178 contributed by George Helffrich <george@geology.bristol.ac.uk>.
180 3. Fixed the tape length calculation when using large tapes
181 and compression. Thanks to Georg Lippold
182 <g_lippold@sourceforge.net> for reporting the bug.
184 4. Added a new set of examples in dump_on_cd_2 directory, based
185 on dump_on_cd examples but somewhat enhanced, supporting DVD
186 media, and localized in english and german. Thanks to
187 Georg Lippold <g_lippold@sourceforge.net> for the new scripts.
189 5. Made dump save 32 bit UID/GID. Internally, this was achieved
190 by switching from the old BSD inode format to the new BSD
191 inode format, which means that the tape format was changed.
192 However, since all restore versions out there should
193 transparently support both inode formats, the change should
194 have no side effects. Thanks to John Yu <jky@cs.bu.edu> for
197 6. Fixed a lot of warnings in the code shown when compiling
198 with 'gcc -W'. Thanks to Matthias Andree
199 <matthias.andree@stud.uni-dortmund.de> for reporting this.
201 7. Fixed a small markup bug in the dump man page. Thanks to
202 Eric S. Raymond <esr@minx.thyrsus.com> for submitting the
205 8. Rewrote entirely the man pages using the tmac.an macro
206 package (Linux man page format) instead of the original BSD
207 format. They should be now cleaner and easier to modify.
209 Changes between versions 0.4b28 and 0.4b29 (released June 8, 2002)
210 ==================================================================
212 1. Fixed a problem in the rmt ioctl command, where ioctl's issued from
213 non Linux clients were misinterpreted. The description of the problem
214 (incompatible numbering in Linux mtio opcodes) is documented at
215 ftp://ftp.fokus.gmd.de/pub/unix/star/README.mtio . Thanks to
216 Jörg Schilling <schilling@fokus.gmd.de> for reporting this bug and
217 providing an excellent, cross-platform replacement for rmt in his
220 2. Fixed a bug reported by Andy Mentges <amentges@jumpline.com>
221 which caused restore to fail when the inode maps were not entirely
222 contained on the first volume (when using really small volumes or
223 when dumping a huge number of inodes).
225 3. Fixed a problem in dump, where files in subdirectories of directories
226 that have the nodump flag set (or being excluded with -e/-E) were
227 sometimes incorrectly dumped (instead of being excluded). The original
228 fix is from David C Lawrence <tale@dd.org> in the FreeBSD version
229 of dump: http://www.FreeBSD.org/cgi/query-pr.cgi?pr=32414
230 Thanks to Ted Grzesik <tedgyz@roostme.com> for reporting the bug and
231 help testing the patch.
233 4. Added some example scripts from Gerd Bavendiek <bav@epost.de>
234 which makes one able to pipe the output of dump, by the net, to
235 a remote CD-burner server.
237 5. Made dump use O_CREAT|O_TRUNC both locally and remotely (over rmt),
238 and use GNU's symbolic syntax over rmt instead of numerical values
239 to assure multiple platform compatibility.
241 6. Documented the -d option in restore.
243 7. Added a -v (verbose) mode to dump. For now it just prints the number
244 of the inode being dumped, but this could evolve in future versions
245 to include interesting debugging output.
247 8. Added a -o flag to restore, which automatically restores the current
248 directory permissions in -i or -x mode, without asking the operator
249 whether to do so. Patch submitted by Tony Clayton <tonyc@e-smith.com>
250 and Peter Samuel <peters@e-smith.com>.
252 Changes between versions 0.4b27 and 0.4b28 (released April 12, 2002)
253 ====================================================================
255 1. Fixed a bug in the QFA feature which could have caused
256 a bad tape positionning on restore (causing extra delays in
257 restore). Credits go to Uwe Gohlke <uwe@ugsoft.de>.
259 2. Added a small note in the dump man page specifying that
260 there should be no white space between the option letter and
261 the -j or -z parameter, thanks to Kenneth Porter <shiva@well.com>
263 3. Made restore work with older versions of the readline library,
264 by checking in configure for several extended symbols. Restore
265 can now be compiled with a readline as old as the 2.0 release
266 (though it may be a good idea to upgrade it to a more recent
267 version...). Thanks to Andrew Donkin <ard@waikato.ac.nz> for
268 reporting the build failures.
270 4. Fixed a performance problem with the QFA file creation in
271 dump, which made unnecessary seeks on the tape slowing down
272 the dump. Thanks to Andrew Donkin <ard@waikato.ac.nz> for
273 reporting this issue.
275 5. Removed the inclusion of some kernel headers in the dump
276 source, which prevented the compile in some kernel/glibc
277 headers/architecture combination. Thanks to Bdale Garbee
278 <bdale@gag.com> for reporting the bug.
280 6. Added the appropriate error message when dump fails to
281 open the output file for writing. Thanks to Amith Varghese
282 <amithv@yahoo.com> for reporting this bug.
284 7. Made restore able to understand large Solaris ufsdump tapes
285 (containing inodes bigger than 4194304). Sun have introduced
286 an "extension" to the dump tape format when dealing with
287 those inodes, which was uncorrectly handled by Linux restore.
288 Thanks to Uwe Gohlke <uwe@ugsoft.de> for reporting the bug and
289 providing a test case.
291 8. Added the -m parameter to dump which optimises the output for
292 inodes having been changed but not modified since the last dump
293 ('changed' and 'modified' have the meaning defined in stat(2)).
294 For those inodes, dump will save only the metadata, instead of
295 saving the entire inode contents. Inodes which are either
296 directories or have been modified since the last dump are saved
297 in a regular way. Uses of this flag must be consistent, meaning
298 that either every dump in an incremental dump set have the flag,
301 Changes between versions 0.4b26 and 0.4b27 (released February 15, 2002)
302 =======================================================================
304 1. Fixed behaviour of dump when exceeding resource limits
307 2. Added the -L flag to restore to allow the user to specify a
308 maximal allowed number of miscompares when using restore
309 with the -C option to check the backup.
311 3. Detailed the manual entry for the -N option of restore.
313 4. Added the -a flag to restore to make able doing unattended
314 restores in -i or -x mode (automatically walks through the
315 multiple dump volumes).
317 5. Extended the QFA mode to work with local files and/or
318 remote tapes and files. This way, restore can know in advance
319 the tape number and the offset for the inodes to extract and
320 can minimize the extraction time by seeking directly to the
323 6. Added the -A <archive> option to both dump and restore,
324 which makes dump to archive a dump table-of-contents in
325 the specified file to be used by restore to determine
326 whether a file is in the dump file that is being restored.
327 (the archive file syntax is also compatible with the
328 Solaris ufsdump generated one).
330 7. Small fix in restore making it able to read some (broken ?)
331 Solaris ufsdump tapes.
333 8. Fixed dump to correctly recognise the root filesystem when using
334 ext2 disk labels (LABEL=/). Thanks to John Yu <jky@it.bu.edu>
335 for reporting this bug.
337 9. Added the -P <file> option to restore to create a
338 Quick File Access file from an already made dump. Patch
339 contributed by Uwe Gohlke <uwe@ugsoft.de>.
341 10. Made restore compile and run on Solaris, making it a
342 possible replacement for the standard ufsrestore. Port was
343 contributed by Uwe Gohlke <uwe@ugsoft.de>.
345 Changes between versions 0.4b25 and 0.4b26 (released January 7, 2002)
346 =====================================================================
348 1. Added a set of backup scripts from Eugenio Diaz
349 <getnito@yahoo.com> in the examples section. It features
350 automatic (cron based) full and incremental dumping of
351 several filesystems on a separate filesystem.
353 2. Fixed a off-by-one miscalculation which disabled dumping
354 a one letter subdirectory. Thanks to Chris Siebenmann
355 <cks@utcc.utoronto.ca> for reporting the bug.
357 3. Fixed several restore bugs occuring when trying to
358 restore some missing files on the tape. Thanks to Chris
359 Siebenmann <cks@utcc.utoronto.ca> for reporting the bug.
361 4. Fixed --with-ldopts configure argument passing, installing from
362 a separate object directory, makefile cleanups contributed
363 by <splite@purdue.edu>.
365 5. Fix a bug which could caused, in some conditions, the highest
366 number inode of a filesystem, to not be dumped. Many thanks
367 to Chris Siebenmann <cks@utcc.utoronto.ca> for helping me
370 Changes between versions 0.4b24 and 0.4b25 (released November 17, 2001)
371 =======================================================================
373 1. Added a mini howto from Patrick Walsh in the examples
376 2. Minor man pages syntax corrections. Thanks to
377 Chris Danis <screechco@home.com> for reporting the bugs.
379 3. Added a script from David B. Peterson <dave@toppledwagon.com>
380 to the examples section. It features dumping several
381 filesystems to a remote tape drive upon ssh.
383 4. Added a patch provided by Richard Jones <rich@annexia.org>
384 which allows BRADEMAX (number of read errors tolerated by
385 dump) to be adjusted using the -I option.
387 5. Fixed a bug which disabled doing "restore -C -f -". Thanks
388 to Clemens Stiglechner <a9401816@unet.univie.ac.at> for the
391 6. Add the -l option to restore to specify if, when doing a
392 remote restore, the file used to access the backup is a
393 regular file (the defaults being a tape drive). Restore needs
394 to know this information when reading a remote compressed
395 dump. Previously, this information was autodetected, but
396 the autodetection code fails (with ioctl: Inappropriate ioctl
397 for device) when using a non Linux remote box. Thanks to
398 many users and especially to Eros Albertazzi
399 <eros@lamel.bo.cnr.it> for reporting this.
401 7. Found a workaroung for the dump deadlock problem (3 childs
402 stuck in pause(), father in read()). The workaround seems
403 to work for me and several beta-testers. If it doesn't work
404 for you, please report back.
406 8. Updated the RPM spec file (BuildPrereq, URL etc).
408 Changes between versions 0.4b23 and 0.4b24 (released September 12, 2001)
409 ========================================================================
411 1. Fixed the permissions of a newly created QFA file by dump.
413 2. Cleaned up the source of dump (the external variables
414 definition was a complete mess, making possible to have
417 3. Fixed restore to use the full tape volume path when doing
418 a compare (since it changes the working directory to the
419 filesystem being compared in the process).
421 4. Added the -q option to dump which makes dump abort
422 whenever it needs operator attention. It should be
423 easier to use dump in scripts with this option.
425 5. Detect the use of incompatible options to dump and
426 refuse them (like -a and -B options together).
428 6. Added bzip2 compression to dump/restore (use option -j level
429 to select it). Note that you will need a restore version
430 >= 0.4b24 in order to restore a bzip2 compressed dump.
431 The same warning as for the zlib compression applies:
432 the tape format of a bzip2 dump is not compatible with the
433 original BSD tape format.
435 7. Fixed a overflow problem in dump corrupting the dump when
436 very large files were encountered. Thanks to Vladimir Nadvornik
439 8. Added a ioctl(BLKFLSBUF) in dump which should flush the
440 kernel buffer/page cache before starting the dump, helping
441 a bit those who use dump on mounted filesystems. Thanks to
442 John Yu <jky@it.bu.edu> and to Theodore T'so <tytso@mit.edu>
445 9. Updated the RPM spec file following the RedHat changes
446 (dynamically linked binaries now in /usr/sbin etc).
448 10. Added a patch from Helmut Jarausch <jarausch@igpm.rwth-aachen.de>
449 which enables restore to recognise multi volume compressed dumps
450 done on CD. Included his scripts for dump (which pipe the dump
451 output directly into cdrecord) and restore. There is now
452 possible to to backups to CD on the fly!
454 Changes between versions 0.4b22 and 0.4b23 (released July 20, 2001)
455 ===================================================================
457 1. Fixed a buffer overflow in restore/tape.c. Patch provided by
458 Marcus Meissner (Caldera International Security Dept.).
460 2. Implement the Sun rmt extended protocol. Patch submitted
461 by Ian Gordon <iangordon@users.sourceforge.net>.
463 3. Check for the e2fsprogs header <ext2fs/ext2_fs.h> instead of
464 the linux kernel header. This ensures that dump always has the
465 latest version of this file. Patch submitted by
466 Andreas Dilger <adilger@turbolinux.com>.
468 4. Report any filesystem present in either /etc/fstab with a
469 positive passno or /etc/dumpdates in dump -w output.
470 Patch submitted by Andreas Dilger <adilger@turbolinux.com>.
472 5. Fixed the looping problem in dump introduced in the
475 6. Changed the -B option of dump to limit the size of
476 _compressed_ output per volume if compression is on.
477 Patch contributed by Helmut Jarausch
478 <jarausch@igpm.rwth-aachen.de>. Note however that, since
479 it is impossible to predict the size of the compressed
480 data before doing the compression, the -B limit is a bit
483 7. Fixed a bug in reading the operator typed file/tape path for
484 the next volume in restore.
486 8. Implemented a "-F script" option to restore which permits the
487 user to specify a script which will be launched at the
488 beginning of each tape, useful for automatic programming of
489 tape changers for example. See the restore man page for the
490 script parameters and return codes.
492 9. Small fix for the QFA routines provided by Uwe Gohlke
493 <uwe@ugsoft.de>, and some recommendations for QFA uses in
496 10. Fixed the multivolume restoring where making a mistake
497 to the 'Mount next tape' prompt caused several blocks to
500 11. Enhanced the -e option of dump to take as a parameter a
501 comma separated list of inode numbers.
503 12. Added the -E option to dump which specify a file containing
504 inode numbers to exclude from the dump.
506 13. Fixed the compressed multi-volume dump + restore.
508 Changes between versions 0.4b21 and 0.4b22 (released May 12, 2001)
509 ==================================================================
511 1. Made dump report the number of blocks dumped per volume.
512 Thanks to Kenneth Porter <shiva@well.com> for the suggestion.
514 2. Fix a bug in dump where waiting too much at the 'change volumes'
515 question caused the volume to be rewritten. Thanks to
516 Graham Reed <greed@users.sourceforge.net> for reporting the
517 bug and providing a patch.
519 3. Added a compression option to dump, contributed by Jerry
520 Peters <gapeters@worldnet.att.net>.
522 WARNING: the compression works only on files/pipes and
523 drives supporting variable block size.
525 WARNING2: tapes created using the compression feature are
526 incompatible with the standard dump tape format, and a
527 version of restore >= 0.4b22 will be needed for extraction.
529 4. Fixed some compilation problems for glibc 2.2.2 and 64 bit
530 architectures. Thanks to Paul Slootman <paul@debian.org> for
531 the patch and to Bdale Garbee <bdale@gag.com> for forwarding
534 5. Many cleanups (CPP defines, const char warnings, check of
535 ext2fs COMPAT flags, time_t cleanups, added libext2 version
536 in dump usage text) by Andreas Dilger <adilger@turbolinux.com>.
538 6. Made --prefix option work in configure. All the install path
539 are now based on the configure parameters.
541 7. Added the Quick File Access mode in dump/restore, contributed
542 by Uwe Gohlke <uwe@ugsoft.de>. In this mode, dump stores in
543 a file tape position for each inode, and this file is used by
544 restore (if called with parameter Q and the filename)
545 to directly position the tape at the file restore is currently
546 working on. This saves hours when restoring single files from
547 large backups, saves the tapes and the drive's head. Use
548 --enable-qfa option of configure to compile in the QFA support.
550 8. Added the possibility to dump several files and directories
551 in a single invocation of dump. Thanks to Uwe Gohlke
552 <uwe@ugsoft.de> for implementing this option.
554 9. Fixed the dumping and restoring of files with holes
555 (files ending with holes didn't get dumped or restored
558 10. Fixed a socket descriptor leak in dump, which leaved opened
559 3 file descriptors per dump process (and there is one dump
562 11. Fixed dump large file system support, by explicit use of
563 open64/lseek64/etc functions (explicit use needed because
564 e2fsprogs libraries don't behave well when compiled with
565 FILE_OFFSET_BITS=64).
567 Changes between versions 0.4b20 and 0.4b21 (released January 13, 2001)
568 ======================================================================
570 1. Fixed some bugs in the dump -w|-W logic introduced by
571 the previous version. Thanks to Andreas Dilger
572 <adilger@turbolinux.com> for his help on this one.
574 2. Fixed again a compilation problem when using old e2fs
575 headers (filesystem label related). Thanks to many users
576 who reported this stupid error.
578 3. Fixed a build problem on old lib5 based systems dealing with
579 _PATH_MNTTAB being undefined. Thanks to John Adams
580 <johna@onevista.com> for reporting the bug.
582 4. Improved the error detection in restore when creating
583 the temporary files in TMPDIR. Now restore will corectly
584 report a 'no space left on device' error instead of
585 strange errors which could imply an archive corruption.
586 Thanks to Gabriel Somlo <somlo@cs.colostate.edu> and
587 bgjenero <bgjenero@sympatico.ca> for reporting the bug.
589 5. Added the throughput information in dump's progression
590 messages. Thanks to Andreas Dilger <adilger@turbolinux.com>
593 6. Use libext2fs's inode scanning routines, which are particularly
594 robust when dealing with errors (especially when having some
595 bad blocks on the filesystem). Many thanks to Colin
596 <colin@horizon.com> for reporting the bug, investigating
597 the issues, finding a workaround, writing the patch and
598 fully testing it... (of course, if this patch will break
599 anything, he is to blame for :-)).
601 7. Made dump and restore LFS aware. Dump can dump a filesystem
602 containing large files, generate a large file on output and
603 restore can restore them. This feature is not enabled by
604 default, use --enable-largefile option of configure to enable
605 it (you need to have a LFS aware glibc though). Thanks to
606 Andrea Arcangeli <andrea@suse.de> for submitting the patch,
607 and to Theodore T'so <tytso@valinux.com> for his always
610 8. Made dump ask upon a tape write error if it should rewrite
611 the current volume (assume this is a bad tape) or if it should
612 assume an end-of-tape condition (useful for tape drives which
613 behaves badly at the end of the tape). Thanks to Andreas
614 Dilger <adilger@turbolinux.com> for the suggestion.
616 Changes between versions 0.4b19 and 0.4b20 (released November 10, 2000)
617 =======================================================================
619 1. Fixed a small compilation problem due to a change
620 in the definintion of the struct sigaction in
621 glibc 2.0 / libc5. Thanks to Gunther Schlegel
622 <schlegel@riege.de> for reporting the bug and to
623 Dave Platt <dplatt@snulbug.mtview.ca.us> for suggesting
626 2. Modified the label and uuid analysis in order to be
627 self-contained (independant of kernel/libc headers). This
628 should fix the compile with older kernel/libc headers and
629 will preserve the functionality. Thanks to Bernhard Erdmann
630 <bernhard.erdmann@gmx.de> for reporting the bug.
632 3. The 'exclude inode' option, if applied to a directory
633 inode, excludes now correctly all the leaves of this
634 directory. Thanks to John R. Dennison
635 <gerdesas@users.sourceforge.net> for reporting the bug.
637 4. Fixed the '-e' option to disable the possibility
638 to exclude the root inode (which causes the dumps to
639 be unreadable by restore). Prevented array overflow
640 when multiple -e options are used.
642 5. Fixed dump to correctly interpret a filesystem argument
643 which is a mountpoint and it is not an absolute path
644 (as specified in the fstab). Thanks to Bernhard R. Erdmann
645 <be@berdmann.de> for reporting the bug.
647 6. Made dump able to backup files larger than 2 GB. Note that
648 dump still doesn't cope with files larger than 4 GB.
650 7. Restore the real uid and gid before invoking an external
651 RSH program (big hole when dump or restore is suid root!).
653 8. Get the values for the default tape device and the location
654 of fstab file from the system headers. Thanks to
655 Andreas Dilger <adilger@turbolinux.com> for the patch.
657 9. Made dump -w|-W report all recognized filesystems
658 present in either /etc/fstab or /etc/dumpdates, and present
659 the list in the same order as in fstab file. Thanks
660 to Andreas Dilger <adilger@turbolinux.com> for the patch.
662 10. Made dump's -a (automatic end of tape detection) the
663 default. Specifying one of -B, -c, -d or -s options will
664 override the EOM detection. Thanks to Andreas Dilger
665 <adilger@turbolinux.com> for the patch.
667 11. Save the ext2 filesystem label into the dump volume label.
668 Specifying a volume label on the command line (-L option)
669 will override this feature. Thanks to Andreas Dilger
670 <adilger@turbolinux.com> for the patch.
672 Changes between versions 0.4b18 and 0.4b19 (released August 20, 2000)
673 =====================================================================
675 1. Fixed the signal handling in dump (which I broke in 0.4b17)
676 which was causing several strange dump failures (dump
677 hanged or segmentation faults etc).
679 2. Specified the default blocksize in the dump man page.
681 3. Changed two info messages of restore to be written on stdout
682 instead of stderr in order to leave stderr only for errors
683 or warnings. Thanks to Stephen Atwell
684 <satwell@urbana.css.mot.com> for the suggestion.
686 4. Corrected an off by one calculation which prevented
687 dumping a directory having a 1 character name length.
688 Thanks to Bernhard Erdmann <bernhard.erdmann@gmx.de>
689 for reporting the bug.
691 5. Reinforce dump in order to allow only level 0 and no
692 -u option when dumping a subdirectory, and document
693 this in the man page. Thanks to Bernhard Erdmann
694 <bernhard.erdmann@gmx.de> for reporting the bug.
696 6. Fixed a small harmless bug in restore which caused
697 in some conditions hard links to be restored several
698 times (therefore generation some warning messages).
699 Thanks to Kenneth Porter <shiva@well.com> for
702 7. Updated the RPM spec file to the latest RedHat version,
703 providing FHS packaging and other cosmetic changes.
704 You will need RPM version >= 3.0.5 in order to build the RPM.
706 8. Updated the configure script to check for libtermcap
707 before checking for libreadline, because we need this
708 library in order to compile the readline support.
710 9. Made dump understand the LABEL= and UUID= notation
711 both in /etc/fstab and on the command line. Note that
712 you will need the /proc filesystem in order to use
713 these notations. Thanks to Erik Troan <ewt@redhat.com>
714 for providing the patch.
716 Changes between versions 0.4b17 and 0.4b18 (released June 30, 2000)
717 ===================================================================
719 1. Fixed a potential buffer overflow in restore. Thanks
720 to Stan Bubrouski <satan@fastdial.net> for reporting
723 2. Fixed a readline-related bug which prevented
724 'cat DUMPFILE | restore -i -f -' from working. Thanks
725 to Charles Karney <karney@users.sourceforge.net>
728 3. Changed a few "panic" into "exit", causing restore to
729 be more stable against some attacks (like the last one
730 reported on Bugtraq, although the last version of restore
731 was not vulnerable - just dumped core). Thanks to
732 Andreas Hasenack <andreas@conectiva.com.br> for reporting
735 4. Removed the suid-root bit on dump and restore in the
736 default build (and generated RPMs). It should be safer
737 now. Users who need the suid-root capabilities in order
738 to make network backups should read first the man page
739 of dump and enable the suid bit manually.
741 5. Added -ltermcap to the compile parameters for restore
742 when using readline support, in order to make the compile
743 process work on some systems (SuSE ?). Thanks to
744 Patrik Schindler <poc@pocnet.net> for reporting the bug.
746 Changes between versions 0.4b16 and 0.4b17 (released June 1st, 2000)
747 ====================================================================
749 1. The -F script is called now *only* at the end of a tape,
750 not at the end of the dump. Thanks to Christian Haul
751 <haul@informatik.tu-darmstadt.de> for the bug report.
753 Normally, the device name and the current volume number
754 are passed on the command line of the script. However,
755 if you want the old style script (with no arguments
756 passed on the command line), you can enable it in
757 configure with the --enable-oldstylefscript.
759 2. Use posix signal handling to preserve dump functionality
760 with libc5. Thanks to Jeff Johnson <jbj@redhat.com> for
763 3. Made the exit code of restore in case of a 'C'ompare
764 command reflect the result of the compare. An exit status
765 of 0 means the dump archive is correct, 1 means tape errors,
766 2 means that some files were modified. Thanks to Kenneth Porter
767 <shiva@well.com> for the suggestion.
769 4. Made (finally) quotes work in interactive restore.
771 5. Small fixes in order to allow dump to compile with a
772 really old e2fsprogs version. Thanks to Ian Zimmerman
773 <itz@speakeasy.org> for the bug report.
775 6. Add GNU readline capabilities to interactive restore.
776 Use configure's --enable-readline flag to enable this feature.
777 Thanks to Patrik Schindler <poc@pocnet.net> for the
780 7. Do the compare on the fly in restore 'C' mode (this will
781 allow not to exhaust the available /tmp space when
782 ccmparing large files). Thanks to Kenneth Porter
783 <shiva@well.com> for the suggestion.
785 Changes between versions 0.4b15 and 0.4b16 (released March 11, 2000)
786 ====================================================================
788 1. Fixed some several duplicate 'DUMP: DUMP:' in the
791 2. Corrected the estimation of blocks to dump. Note that
792 this is still wrong for large directory inodes, due
793 to the size of a BSD directory entry on the tape
794 (estimation is based on the size of the ext2 directory,
795 which is smaller because it doesn't contain the null
796 character at the end).
798 3. Made dump report the total number of MB written to
799 tape at the end of run. Thanks to W. Reilly Cooley
800 <wcooley@nakedape.cc> for the patch.
802 4. Added the -X option to restore giving the possibility
803 to read the names of the files to be extracted/listed
804 from a text file (in addition of the command line).
805 Thanks to Dejan Muhamedagic <dejan@quant-x.com> for the
808 5. Added the device name and the current volume number
809 as arguments to the end of tape script (dump -F option).
811 6. Made the multi-volume dump work again (after having
812 broken it in 0.4b15).
814 Changes between versions 0.4b14 and 0.4b15 (released March 2, 2000)
815 ===================================================================
817 1. Added a prompt command in interactive restore mode. Thanks
818 to Andreas Dilger <adilger@home.com> for the patch.
820 2. Fixed a buffer overflow problem in dump (caused by
821 not checking the size of the filesystem parameter).
822 Thanks to Kim Yong-jun <loveyou@hackerslab.org> for
823 reporting this on Bugtraq (and to several dump users
824 who forwarded me his mail).
826 3. Added the '-F script' option to dump in order to
827 launch a script at the end of each tape (to be used
828 with a tape changer, or to notify the sysadmin by
831 4. Fixed a bug in restore compare code caused by the changes
834 5. Fixed the treatment of options using the old BSD syntax
835 in both dump and restore.
837 Changes between versions 0.4b13 and 0.4b14 (released February 10, 2000)
838 =======================================================================
840 1. Fixed a bug in dump which may have caused invalid deleted
841 directories to be dumped out if they were deleted after the
842 mapping pass. This could occure on active filesystem and lead
843 to heap corruption (causing dump malfunction in many possible ways).
844 Thanks to Jan Sanislo <oystr@cs.washington.edu> for finding this
845 bug and submitting the patch.
847 2. Fixed the handling of the filesystem parameter in dump. A
848 '/mnt/disk' parameter caused the disk contents to be dumped,
849 but a '/mnt/disk/' parameter caused the mountpoint directory
850 to be dumped (generally an empty directory).
852 3. Improved the output of dump in order to tell which directory
853 it is currently dumping (when dumping a subtree).
855 4. Added the '-e' exclude inode option to dump. Thanks to
856 Isaac Chuang <ike@isl.stanford.edu> for contributing with the patch.
858 5. Added a REPORTING-BUGS file in order to provide a guide
859 on how to correctly report a bug in dump/restore.
861 6. Fixed a restore problem when restoring a hard link to an inode
862 having the immutable or append-only attribute set. Thanks to
863 Ambrose Li <acli@mingpaoxpress.com> for submitting the patch.
865 7. Fixed a compatibility problem between dumps made on little
866 endian machines (the format was correct) and big endian
867 machines (the format was incorrect). This fix break the
868 compatibility with the older dumps made on big endian
869 machines (sparc, m86k, ppc etc). For the first time in
870 linux dump's history (I believe), the dumps made by *BSD,
871 Linux/alpha, Linux/sparc and Linux/x86 are compatible,
872 so interchangeable. Thanks to Rob Cermak
873 <cermak@ahab.rutgers.edu> for submitting the bug and
874 helping me test the fix.
876 8. Fixed the way dump reports the remaining percent/time, if
877 the number of blocks actually dumped exceeds the estimated
878 number of blocks. Thanks to Jean-Paul van der Jagt
879 <jeanpaul@dutepp0.et.tudelft.nl> for reporting the bug.
881 Changes between versions 0.4b12 and 0.4b13 (released January 21, 2000)
882 ======================================================================
884 1. Small Y2K fix in the man pages :). Thanks to Bernhard Sadlowski
885 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug.
887 2. Removed the requirement to build the RPM as root from the
888 spec file. Thanks to Christian Weisgerber
889 <naddy@mips.rhein-neckar.de> for submitting this.
891 3. Fixed a bug in dump related to the 'filetype' feature of ext2fs,
892 causing dump to block when dumping really huge filesystems.
893 Many thanks to Patrik Schindler <poc@pocnet.net> for
894 helping me find this bug.
896 4. Fixed the treatment for an interrupt signal when dump access
897 the remote tape through RSH. Thanks to Christian Weisgerber
898 <naddy@mips.rhein-neckar.de> for providing the patch.
900 5. Fixed a bug which was causing dump/restore to display
901 garbage characters instead of the remote host name.
903 Changes between versions 0.4b11 and 0.4b12 (released January 8, 2000)
904 =====================================================================
906 1. Small fix in the dump man page. Thanks to Thorsten Kukuk
907 <kukuk@suse.de> for submitting the patch.
909 2. Fix for the exit code when using the size estimate option of
910 dump. Thanks to Matti Taskinen <mkt@rni.helsinki.fi> for
911 submitting the patch.
913 3. Handle EINTR in atomical reads/writes in dump, which was causing
914 dump to fail on some systems. Thanks to Eric Jergensen
915 <eric@dvns.com> for reporting the bug and submitting the patch.
917 4. Handle more than 16 characters for the device names in dumpdates.
918 (up to 255 now). Thanks to Rainer Clasen <bj@ncc.cicely.de> for
919 tracking down the problem and proposing the solution.
921 5. Fixed a bug in dump which prevented the creation of the
922 dumpdates file when doing a 0-level dump without already
923 having a dumpdates file. Thanks to Patrik Schindler
924 <poc@pocnet.net> for reporting the bug.
926 6. Changed the way dump 'S' flag reports the size estimate
927 from number of blocks into bytes (making it compatible
928 with the Solaris version, and simplifying things for
929 amanda users). Thanks to Jason L Tibbitts III
930 <tibbs@math.uh.edu> for reporting the bug.
932 7. Fixed a compatibility problem in linux/alpha dump tape format.
933 Now the linux/alpha dump are (again) compatible with the
934 other dump formats. But this breaks compatibility with
935 older dumps made on alpha. Thanks to Mike Tibor
936 <tibor@lib.uaa.alaska.edu> for helping me in finding this bug.
938 Changes between versions 0.4b10 and 0.4b11 (released December 5, 1999)
939 ======================================================================
941 1. Added a '--enable-kerberos' to configure.
943 2. Added a 'S' option to dump which determines the amount of space
944 that is needed to perform the dump without actually doing it, similar
945 to the Sun's ufsdump 'S' option. Patch contributed by Rob Cermak
946 <cermak@ahab.rutgers.edu>.
948 3. Added a 'M' multi-volume option to dump and restore which enables
949 dumping to multiple files (useful when dumping to an ext2
950 partition to make several dump files in order to bypass the 2GB
951 file size limitation). The 'f' argument is treated as a prefix and
952 the output files will be named <prefix>001, <prefix>002 etc. With
953 the 'M' flag, restore automatically selects the right file without
954 asking to enter a new tape each time.
956 4. Fixed a memory leak which was causing dump to grow very big
957 (270MB when dumping a 10GB filesystem...). Thanks to Jason
958 Fearon <jasonf@netrider.org.au> for reporting the bug.
960 Changes between versions 0.4b9 and 0.4b10 (released November 21, 1999)
961 ======================================================================
963 1. Make configure test if the system glob routines support
964 extended syntax (ALTDIRFUNC). If not, use the internal glob
965 routines instead of system ones. Thanks to Bernhard Sadlowski
966 <sadlowsk@Mathematik.Uni-Bielefeld.DE> for reporting the bug
967 and helping me resolve this and other minor libc5 compiling
970 2. Fix a problem when dumping a ext2fs with the 'filetype'
971 feature enabled. Thanks to Patrick J. LoPresti
972 <patl@cag.lcs.mit.edu> for reporting the bug and to
973 Theodore Y. Ts'o <tytso@mit.edu> for providing the patch.
975 3. Made the nodump flag work on directories. A directory which
976 has the nodump flag gets never dumped, regardless of its
979 4. Integrate a patch from Jeremy Fitzhardinge <jeremy@goop.org>
980 which allows dump on an active ext3 filesystem. However, this
981 is a "quick and dirty" patch which enables backup of an ext3
982 filesystem through the ext2 compatibility (by ignoring the
983 NEEDS_RECOVERY bit). The journal file is not recognized and
984 it is dumped (it should not).
986 5. Test the superblock compatibility flags when dumping, in order
987 to be sure that we know how to deal with specific features.
989 Changes between versions 0.4b8 and 0.4b9 (released November 5, 1999)
990 ====================================================================
992 1. Use lchown instead of chown, fixing a possible security problem
993 when restoring symlinks (a malicious user could use this
994 to deliberately corrupt the ownership of important system files).
995 Thanks to Chris Siebenmann <cks@utcc.utoronto.ca> for detecting
996 this and providing the patch.
998 Changes between versions 0.4b7 and 0.4b8 (released November 3, 1999)
999 ====================================================================
1001 1. Put dump sources under CVS, added Id tags in all files so
1002 one can use 'ident' on binary files.
1004 2. Added the dump/restore version in the usage text so one can
1005 easily verify the version he is using.
1007 3. Small patch from Nuno Oliveira <nuno@eq.uc.pt> which fixes
1008 a va_start/va_end problem on linux-ppc (always call va_start
1009 va_end in pairs each time we use a vararg function).
1011 4. Added again the DT_* constants because old libc does not
1012 contain them :(. Thanks to Eric Maisonobe <virnet@nat.fr>
1013 for submitting the bug report.
1015 5. Use ext2fs_llseek instead of llseek. With recent e2fsprogs
1016 this should enable dumping big (huge) filesystems.
1018 6. Added the RSH environment variable in order to be able to
1019 use a rsh replacement like ssh when doing remote backups (and
1020 bypass the security limitations of rcmd). Now you can do remote
1021 backups without being root (or making dump setuid root).
1023 7. Modified again the way dumpdates works. For incremental dumps,
1024 we need to read dumpdates even if we are not using 'u' option.
1025 Thanks to Bdale Garbee <bdale@gag.com> for his ideas on how
1028 Changes between versions 0.4b6 and 0.4b7 (released October 8, 1999)
1029 ===================================================================
1031 1. Removed the 'k' flag from the restore 'about' text if kerberos
1032 was not compiled in.
1034 2. Prototyped (f)setflags from e2fsprogs and corrected the calls
1035 to them (fsetflags takes a char*, setflags an open fd!).
1037 3. (f)setflags is called only if the flags aren't empty. If the
1038 file is a special file, a warning is printed, because changing
1039 flags implies opening the device. Normally, a special file
1040 should not have any flag... (Debian bug #29775, patch provided
1041 by Abhijit Dasgupta <abhijit@ans.net>).
1043 4. Made possible to dump a file system not mentioned in /etc/fstab.
1044 (Debian bug #11904, patch provided by Eirik Fuller <eirik@netcom.com>).
1046 5. Changed the default behaviour to not create dumpdates
1047 unless 'u' option is specified. Removed the old "debian-patch"
1048 which provided the same thing. (Debian bug #38136, #33818).
1050 6. Removed all those dump*announce, since they were getting old...
1052 7. Added warning messages if dumpdates does not exist and
1053 when an inferior level dump does not exist (except for a level 0
1056 8. Debugged the glob calls in interactive mode: restore used a
1057 dirent struct which was different from the /usr/include/dirent.h
1058 one (this used to work, is it a glibc2 change?), so none of the
1059 compat glob (which used /usr/include/dirent.h) or the system glob
1060 worked. Restore use now the system dirent (and the system
1061 DT_* constants), which are compatible with BSD ones.
1063 9. Added a configure flag (--with-dumpdatespath) to specify
1064 the location of dumpdates file. By default, it is
1067 10. Added the "AUTHOR" and "AVAILABILITY" sections and
1068 included the current date/version in man pages.
1070 11. Corrected the estimation of remaining time when
1071 the operator doesn't change the tapes quickly enough. This
1072 was an old bug, I thought I corrected it, and discovered
1073 that in fact it was corrected in two different places, so
1074 the results canceled each other...
1076 Changes between versions 0.4b5 and 0.4b6 (released October 1, 1999)
1077 ===================================================================
1079 1. Integrated multiple patches from RedHat, Debian and SuSE:
1081 - tweak dump/itime.c to not try to read dumpdates if the 'u' option
1083 - several fixes in the man pages.
1084 - update the default tape device to /dev/st0.
1085 - many updates for Linux Alpha (byte ordering, size_t etc).
1087 - use environment variable for TMPDIR (instead of /tmp).
1088 - use sigjmp_buf instead of jmp_buf (RedHat bug #3260).
1089 - workaround egcs bug (RedHat bugs #4281 and #2989).
1090 - wire $(OPT) throughout Makefile's.
1092 2. Upgrade the dump revision to 1, making possible to dump filesystems
1093 made with e2fsprogs-1.15 or newer. Nothing seems to break...
1095 3. Fix some compile warnings, prototype all functions.
1097 4. Use glibc err/glob instead of internal compatibility
1098 routines (only if available).
1100 5. Fix a compile error on Linux 2.2.7 / libc5 (5.4.44) (patch provided
1101 by Bernhard Sadlowski <sadlowsk@mathematik.uni-bielefeld.de>).
1103 Changes between versions 0.4b4 and 0.4b5 (released September 22, 1999)
1104 ======================================================================
1106 1. Integrated the changes from FreeBSD-3.1-RELEASE
1107 (mostly bug fixes, buffer overruns, dump has now an "automatic
1108 tape length calculation" flag, dump/restore can use kerberos now
1109 (this is NOT tested), use environment variables for TAPE and
1112 2. Integrated three RedHat patches ("glibc", "kernel" and "bread" patches)
1114 3. Corrected a bug in restore when using 'C' option with multi-volumes
1115 tapes (files splited accros two tapes give "size changed" errors
1118 4. Corrected the long standing bug when dumping multiple tapes.
1119 This works for me, needs further testing.
1121 Changes between versions 0.4b3 and 0.4b4 (released January 17, 1997)
1122 ====================================================================
1124 1. Dump now runs correctly on kernels 2.1.x
1125 Fix made by Gerald Peters <gapeters@worldnet.att.net>
1127 Changes between versions 0.4b2 and 0.4b3
1128 ========================================
1130 1. Use realpath() if available
1132 2. Report statistics
1134 Changes between versions 0.4b1 and 0.4b2
1135 ========================================
1137 1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
1140 2. Fixed restore to make it able to read FreeBSD 2.x dumps again
1142 3. Fixed configure.in to correctly handle --enable-rmt
1144 Changes between versions 0.3 and 0.4b1
1145 ======================================
1147 1. Integrated the changes from 4.4BSD-Lite2
1149 2. Integrated the patches from Debian and Red Hat
1151 3. Portability changes: use the __u32, __u16, __s32, and __s16 types
1153 4. Changed dump to use the Ext2fs library to get block addresses. This
1154 should solve the endianness problem on SparcLinux.
1156 5. Created a configure.in file (shamelessly stolen from the e2fsprogs
1157 distribution's one) to use autoconf
1159 6. Fixed a few minor bugs
1161 Changes between versions 0.2e and 0.2f
1162 ======================================
1164 1. Added the creation of named pipes (fifos) in restore.
1166 2. Added the -N flag in the restore manual page.
1168 3. Added the file kernel.patch which contains the llseek() optimization
1169 patch for 1.2.x kernels.
1171 4. Fixed a bug in the restoration of symbolic links: owner and group were
1174 5. Integrated some changes from FreeBSD 2.2.
1176 6. Added a call to ftruncate() after restoring each file to restore
1177 correctly files ending by a hole.
1179 Changes between versions 0.2d and 0.2e
1180 ======================================
1182 1. Fixed a bug in the "set owner/mode" process. Every file was restored
1183 with owner = root (0) and group = root/wheel/whatever (0).
1185 Changes between versions 0.2c and 0.2d
1186 ======================================
1188 1. Dump is now able to backup 2GB+ filesystems.
1190 2. Dump and restore can now be linked as static binaries.
1192 Changes between versions 0.2b and 0.2c
1193 ======================================
1195 1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
1197 Changes between versions 0.2a and 0.2b
1198 ======================================
1200 1. Really fixed the bug that I should have corrected in 0.2a.
1202 2. Enabled optimization again.
1204 Changes between versions 0.2 and 0.2a
1205 =====================================
1207 1. Disabled the optimization during compilation.
1209 Changes between versions 0.1 and 0.2
1210 ====================================
1212 1. Fixed a bug in fstab.c which caused a null pointer to be stored in
1213 the fs_type field (actually, I modified the file fstab.c to make it
1214 use the mntent functions).
1216 2. Dump and restore now use a 4.3 BSD compatible dump format. Backups
1217 made by dump should be readable by the BSD restore and backups made
1218 by the BSD dump should be readable by restore. Unfortunately, this
1219 means that the dump format has changed between version 0.1 and version
1222 3. Dump is now able to backup a subtree, it is no longer limited to whole
1223 filesystems like the BSD version.
1225 4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger
1228 Changes between versions 0.0 and 0.1
1229 ====================================
1231 1. Now create links rdump and rrestore during the `make install' step.
1233 2. Linux port specific bugs added to the manual pages
1235 3. Incorrect estimation of the number of tapes blocks fixed when doing
1236 incremental backups.
1238 4. Better ls-like format in restore in interactive mode.
