+
+Changes between versions 0.4b3 and 0.4b4
+========================================
+
+1. Dump now runs correctly on kernels 2.1.x
+ Fix made by Gerald Peters <gapeters@worldnet.att.net>
+
+Changes between versions 0.4b2 and 0.4b3
+========================================
+
+1. Use realpath() if available
+
+2. Report statistics
+
+Changes between versions 0.4b1 and 0.4b2
+========================================
+
+1. Fixed the bug fix from Greg Lutz (I had made a mistake when integrating
+ the patch)
+
+2. Fixed restore to make it able to read FreeBSD 2.x dumps again
+
+3. Fixed configure.in to correctly handle --enable-rmt
+
+Changes between versions 0.3 and 0.4b1
+======================================
+
+1. Integrated the changes from 4.4BSD-Lite2
+
+2. Integrated the patches from Debian and Red Hat
+
+3. Portability changes: use the __u32, __u16, __s32, and __s16 types
+
+4. Changed dump to use the Ext2fs library to get block addresses. This
+ should solve the endianness problem on SparcLinux.
+
+5. Created a configure.in file (shamelessly stolen from the e2fsprogs
+ distribution's one) to use autoconf
+
+6. Fixed a few minor bugs
+
+Changes between versions 0.2e and 0.2f
+======================================
+
+1. Added the creation of named pipes (fifos) in restore.
+
+2. Added the -N flag in the restore manual page.
+
+3. Added the file kernel.patch which contains the llseek() optimization
+ patch for 1.2.x kernels.
+
+4. Fixed a bug in the restoration of symbolic links: owner and group were
+ not restored.
+
+5. Integrated some changes from FreeBSD 2.2.
+
+6. Added a call to ftruncate() after restoring each file to restore
+ correctly files ending by a hole.
+
+Changes between versions 0.2d and 0.2e
+======================================
+
+1. Fixed a bug in the "set owner/mode" process. Every file was restored
+ with owner = root (0) and group = root/wheel/whatever (0).
+
+Changes between versions 0.2c and 0.2d
+======================================
+
+1. Dump is now able to backup 2GB+ filesystems.
+
+2. Dump and restore can now be linked as static binaries.
+
+Changes between versions 0.2b and 0.2c
+======================================
+
+1. Fixed a bug when dumping ``slow'' (i.e. normal) symbolic links.
+
+Changes between versions 0.2a and 0.2b
+======================================
+
+1. Really fixed the bug that I should have corrected in 0.2a.
+
+2. Enabled optimization again.
+
+Changes between versions 0.2 and 0.2a
+=====================================
+
+1. Disabled the optimization during compilation.
+
+Changes between versions 0.1 and 0.2
+====================================
+
+1. Fixed a bug in fstab.c which caused a null pointer to be stored in
+ the fs_type field (actually, I modified the file fstab.c to make it
+ use the mntent functions).
+
+2. Dump and restore now use a 4.3 BSD compatible dump format. Backups
+ made by dump should be readable by the BSD restore and backups made
+ by the BSD dump should be readable by restore. Unfortunately, this
+ means that the dump format has changed between version 0.1 and version
+ 0.2 :-(
+
+3. Dump is now able to backup a subtree, it is no longer limited to whole
+ filesystems like the BSD version.
+
+4. Dump now uses ext2_llseek() so it is able to backup filesystems bigger
+ than 2 GB.
+
+Changes between versions 0.0 and 0.1
+====================================
+
+1. Now create links rdump and rrestore during the `make install' step.
+
+2. Linux port specific bugs added to the manual pages
+
+3. Incorrect estimation of the number of tapes blocks fixed when doing
+ incremental backups.
+
+4. Better ls-like format in restore in interactive mode.

+
+ Installation of the dump/restore port should be quite easy, since
+a configure script is now provided.
+
+ Configuration is made by running the configure script. Run
+`configure --help' to get a list of options.
+
+ After configuring the package, you can type `make' to compile the
+programs, and `make install' to install the binaries in /sbin and the
+manual pages in `/usr/man/man8'.
+
+ You need to have the latest Ext2fs programs installed on your system
+since this version of dump uses the Ext2fs library written by Theodore T'so.
+The Ext2fs programs distribution is available from tsx-11.mit.edu in the
+directory /pub/linux/packages/ext2fs.
--- /dev/null
+Known bugs and limitations of the dump/restore port
+===================================================
+
+1. Multi-volume does not work: restore does not succeeds in
+ resynchronizing itself on a multi-volume dump. Thus, some files are
+ not restored.
+
+2. I have tried to minimize changes in the BSD source and some parts
+ may look ugly. dump/tape.c is really awfull but this is pure BSD
+ code :-) Maybe, I should replace it with a simpler and cleaner
+ version.

+Dump and restore were written by the people of the CSRG at the University
+of California, Berkeley.
+
+They were ported to Linux by Remy Card <card@Linux.EU.Org>, by using
+the Ext2fs library, written by Theodore Ts'o <tytso@mit.edu>.
+
+Kevin Layer <layer@Franz.COM> added the comparison code in restore.
+
+Doug Paul <dbp@dragonsys.com> helped me to make dump able to backup 2GB+
+filesystems.
+
+David Frey <david@eos.lugs.ch> (the Debian dump maintainer) and the people
+from Red Hat Software provided lots of patches.
+
+Thanks to people who reported problems with the port, sent patches, and
+suggested various improvements.
+Here is a partial list of them (if I have forgotten someone, please complain):
+
+Henry Katz hkatz@hkatz.dialup.access.net
+Klaus Kudielka kkudielk@cacofonix.nt.tuwien.ac.at
+Florian La Roche florian@jurix.jura.uni-sb.de

+1. Fix the multi-volume problem (is there one after all?, I could not
+ reproduce it and some people told me that multi-volume dumps were Ok).
+
+2. Make dump honor the no-dump attribute on directories. Currently, it
+ honours it only on files. This means that a directory flagged with
+ the no-dump attribute will be dumped if it contains a file without
+ the no-dump flag.
+
+3. Change the way rdump and rrestore call rmt. Currently, rcmd() is used
+ but it may be better to call rsh. I have to look at the GNU tar code.
+
+4. Make dump able to backup several directories and/or files in one
+ invocation, like the SunOS version.

+
+ Finally... The public test version of my port of the 4.4BSD dump
+and restore programs to Linux is now available on tsx-11.mit.edu in the
+directory /pub/linux/packages/ext2fs.
+
+ This port understands the Ext2fs structure and is able to backup
+and restore Linux Ext2 filesystems. This is a test version and I have only
+made minimal testing so do not rely too much on it for your backups.
+
+ This version of dump contains all the BSD features and also includes
+some enhancements over the previous test versions:
+ - it is possible to backup a subtree instead of a whole filesystem,
+ - some bugs have been fixed :-)
+ - dump is now able to backup filesystems bigger than 2 GB,
+ - the dump format is now compatible with 4.3BSD. This means that you
+ can restore Linux dumps on BSD based operating systems and you can
+ restore BSD dumps on Linux. I have made some tests with FreeBSD
+ and SunOS 4.1.3 and this works fine. I am interested in reports
+ about other BSD based operating systems.
+
+ I am not sure that multi-volume dumps are Ok. If you use them, please
+send me a bug (or success :-) report.
+
+ The dump format is *not* compatible with the previous test versions
+(versions 0.0 and 0.1), which were distributed as private test versions. If
+you have backups made by dump 0.0 or 0.1, restore 0.2 will not be able to
+read them.
+
+ You need the latest ext2fs programs source distribution to compile dump
+and restore because I have used Theodore T'so's Ext2fs library. The latest
+version (0.5b) of these programs is available on tsx-11.mit.edu in the
+directory /pub/linux/packages/ext2fs. If you want to build ELF binaries, you
+also need to get my ELF patch on ftp.ibp.fr in /pub/linux/ELF/patches.
+
+ I'd like to thank all the people who have used the private test
+versions of dump and restore. I have appreciated their feedback that has
+helped me to improve dump and restore.

+
+ I have received bug reports about dump telling that dump receives
+unexpected signals when dump directories (in pass III). I have tried to
+reproduce the problem and it appears that this may be caused by an optimization
+problem in some versions of gcc. Dump works fine when compiled with
+optimization by gcc 2.6.2 but it fails when compiled by gcc 2.6.3:
+ - either it gets an unexpected signal (SIGFPE),
+ - or it issues warnings ``Warning: dumpdirino called with file type
+ 040000'' and does not dump directories.
+
+ I am not courageous enough to study the assembly code generated by
+gcc (yet :-), so I have modified the Makefiles to compile dump without
+optimizations. I have also fixed a few minor bugs and removed some printf's
+that I had added during my tests. I will study the assembly code generated
+by gcc soon and fix the problem.
+
+ The fixed version (numbered 0.2a) is now available on tsx-11.mit.edu
+in the directory /pub/linux/packages/ext2fs. Please get it if you are using
+dump and restore.
+
+ Thanks to Daniel Veillard <Daniel.Veillard@imag.fr>, Bob Snyder
+<rsnyder@janet.advsys.com>, and Florian La Roche <rzsfl@rz.uni-sb.de> for

+
+ Finding the problem was not an easy task because the behavior seemed
+to be related to the version of the compiler. Anyway, I have found it :-)
+There was an incorrect assignement in the function dumpdirino(), which is
+responsible for dumping the contents of directories, and this caused some
+problems when compiled with optimizations by some versions of gcc. After
+fixing the problem, dump runs fine when compiled by gcc 2.6.3 or gcc 2.7.0.
+
+ The new fixed version (numbered 0.2b) is now available on
+tsx-11.mit.edu in the directory /pub/linux/packages/ext2fs. Please get it

+/pub/linux/packages/ext2fs.
+
+ A stupid bug in the "set owner/mode" pass has been fixed. Files were
+restored with uid=0 and gid=0. The bug was in restore, not in dump, so this
+means that backups made with dump 0.2d are Ok. Thanks to Brent Olson
+<night@halcyon.com> for reporting this problem.
+
+ Thanks also to the patience of the testers :-)
+
+ I remind you that dump and restore should be considered as software
+in BETA test. Don't rely too much on them for your backups...

+
+ Ok, I'm back ;-)
+
+ Dump 0.3 is now available on tsx-11.mit.edu in the directory
+/pub/linux/packages/ext2fs.
+
+ Restore is now able to restore named pipes (fifos). Thanks to
+Jason Venner <jason@idiom.com> for reporting the bug. I have also fixed
+a bug in the symlink restoration: owner and group were not set by previous
+version. Thanks to Klaus Kudielka <kkudielk@cacofonix.nt.tuwien.ac.at> for
+reporting it. Restore is now able to restore correctly files ending with
+a hole (mainly DLL shared libraries under Linux). Thanks to David Monro
+<davidm@cs.su.oz.au> for sending me a patch much cleaner than mine :-)
+
+ Kevin Layer <layer@Franz.COM> has implemented a verify option in
+restore. It is now possible to check a dump against the contents of the
+filesystem. Thank you very much, Kevin!
+
+ Some bug fixes from FreeBSD 2.2-current have also been integrated.
+
+ Last, I have added the file `linux-1.2.x.patch' in the distribution.
+This patch for 1.2 kernels should be applied if you want to get better
+performances.
+
+ I remind you that dump and restore should be considered as software
+in BETA test. Don't rely too much on them for your backups...

+
+ A test release of dump 0.4 is now available on tsx-11.mit.edu,
+in the file /pub/linux/ALPHA/ext2fs/dump-0.4b1.tar.gz.
+
+ This new version is based on the latest dump and restore suite
+available from Berkeley (I have integrated the changes from 4.4BSD-Lite2).
+
+ It also includes lots of changes from the Debian 1.2 and Red Hat 4.0
+distributions (I have included most of the patches made by maintainers of
+these distributions).
+
+ Some changes were made to improve the portability of dump and restore:
+ - fixed size types are now used, so that the dump format is the same
+ on every architecture supported by Linux,
+ - dump now uses the Ext2fs library to get the block addresses
+ to solve an endianness problem that was present on SparcLinux.
+
+ Autoconf is now used to configure dump and restore. I have shamelessly
+adapted the configure script from the one present in the e2fsprogs
+distribution (thanks Ted!).
+
+ Last, a few minor bugs have been fixed.
+
+ This version is a test release. Use it only for testing :-) New
+beta versions will probably be released before a stable dump 0.4 version is
+available.
+
+ If you encounter problems with this test release, please send a
+detailled bug report (please look at the file KNOWNBUGS before sending a
+bug report).

+.in -\\n(iSu
+(The
+.Bx 4.3
+option syntax is implemented for backward compatibility, but
+is not documented here.)
+.Sh DESCRIPTION
+.Nm Dump
+examines files
+on a filesystem
+and determines which files
+need to be backed up. These files
+are copied to the given disk, tape or other
+storage medium for safe keeping (see the
+.Fl f
+option below for doing remote backups).
+A dump that is larger than the output medium is broken into
+multiple volumes.
+On most media the size is determined by writing until an
+end-of-media indication is returned.
+On media that cannot reliably return an end-of-media indication
+(such as some cartridge tape drives)
+each volume is of a fixed size;
+the actual size is determined by the tape size and density and/or
+block count options below.
+By default, the same output file name is used for each volume
+after prompting the operator to change media.
+.Pp
+The following options are supported by
+.Nm dump :
+.Bl -tag -width Ds
+.It Fl 0\-9
+Dump levels.
+A level 0, full backup,
+guarantees the entire file system is copied
+(but see also the
+.Fl h
+option below).
+A level number above 0,
+incremental backup,
+tells dump to
+copy all files new or modified since the
+last dump of the same or lower level.
+The default level is 9.
+.It Fl B Ar records
+The number of dump records per volume.
+This option overrides the calculation of tape size
+based on length and density.
+.It Fl b Ar blocksize
+The number of kilobytes per dump record.
+.It Fl c
+Modify the calculation of the default density and tape size to be more
+appropriate for cartridge tapes.
+.It Fl d Ar density
+Set tape density to
+.Ar density .
+The default is 1600BPI.
+.It Fl f Ar file
+Write the backup to
+.Ar file ;
+.Ar file
+may be a special device file
+like
+.Pa /dev/rmt12
+(a tape drive),
+.Pa /dev/rsd1c
+(a disk drive),
+an ordinary file,
+or
+.Ql Fl
+(the standard output).
+Multiple file names may be given as a single argument separated by commas.
+Each file will be used for one dump volume in the order listed;
+if the dump requires more volumes than the number of names given,
+the last file name will used for all remaining volumes after prompting
+for media changes.
+If the name of the file is of the form
+.Dq host:file ,
+or
+.Dq user@host:file ,
+.Nm dump
+writes to the named file on the remote host using
+.Xr rmt 8 .
+.It Fl h Ar level
+Honor the user
+.Dq nodump
+flag
+.Dp Dv UF_NODUMP
+only for dumps at or above the given
+.Ar level .
+The default honor level is 1,
+so that incremental backups omit such files
+but full backups retain them.
+.It Fl n
+Whenever
+.Nm dump
+requires operator attention,
+notify all operators in the group
+.Dq operator
+by means similar to a
+.Xr wall 1 .
+.It Fl s Ar feet
+Attempt to calculate the amount of tape needed
+at a particular density.
+If this amount is exceeded,
+.Nm dump
+prompts for a new tape.
+It is recommended to be a bit conservative on this option.
+The default tape length is 2300 feet.
+.ne 1i
+.It Fl T Ar date
+Use the specified date as the starting time for the dump
+instead of the time determined from looking in
+.Pa /etc/dumpdates .
+The format of date is the same as that of
+.Xr ctime 3 .
+This option is useful for automated dump scripts that wish to
+dump over a specific period of time.
+The
+.Fl T
+option is mutually exclusive from the
+.Fl u
+option.
+.It Fl u
+Update the file
+.Pa /etc/dumpdates
+after a successful dump.
+The format of
+.Pa /etc/dumpdates
+is readable by people, consisting of one
+free format record per line:
+filesystem name,
+increment level
+and
+.Xr ctime 3
+format dump date.
+There may be only one entry per filesystem at each level.
+The file
+.Pa /etc/dumpdates
+may be edited to change any of the fields,
+if necessary.
+.It Fl W
+.Nm Dump
+tells the operator what file systems need to be dumped.
+This information is gleaned from the files
+.Pa /etc/dumpdates
+and
+.Pa /etc/fstab .
+The
+.Fl W
+option causes
+.Nm dump
+to print out, for each file system in
+.Pa /etc/dumpdates
+the most recent dump date and level,
+and highlights those file systems that should be dumped.
+If the
+.Fl W
+option is set, all other options are ignored, and
+.Nm dump
+exits immediately.
+.It Fl w
+Is like W, but prints only those filesystems which need to be dumped.
+.El
+.Pp
+.Nm Dump
+requires operator intervention on these conditions:
+end of tape,
+end of dump,
+tape write error,
+tape open error or
+disk read error (if there are more than a threshold of 32).
+In addition to alerting all operators implied by the
+.Fl n
+key,
+.Nm dump
+interacts with the operator on
+.Em dump's
+control terminal at times when
+.Nm dump
+can no longer proceed,
+or if something is grossly wrong.
+All questions
+.Nm dump
+poses
+.Em must
+be answered by typing
+.Dq yes
+or
+.Dq no ,
+appropriately.
+.Pp
+Since making a dump involves a lot of time and effort for full dumps,
+.Nm dump
+checkpoints itself at the start of each tape volume.
+If writing that volume fails for some reason,
+.Nm dump
+will,
+with operator permission,
+restart itself from the checkpoint
+after the old tape has been rewound and removed,
+and a new tape has been mounted.
+.Pp
+.Nm Dump
+tells the operator what is going on at periodic intervals,
+including usually low estimates of the number of blocks to write,
+the number of tapes it will take, the time to completion, and
+the time to the tape change.
+The output is verbose,
+so that others know that the terminal
+controlling
+.Nm dump
+is busy,
+and will be for some time.
+.Pp
+In the event of a catastrophic disk event, the time required
+to restore all the necessary backup tapes or files to disk
+can be kept to a minimum by staggering the incremental dumps.
+An efficient method of staggering incremental dumps
+to minimize the number of tapes follows:
+.Bl -bullet -offset indent
+.It
+Always start with a level 0 backup, for example:
+.Bd -literal -offset indent
+/sbin/dump -0u -f /dev/nrst1 /usr/src
+.Ed
+.Pp
+This should be done at set intervals, say once a month or once every two months,
+and on a set of fresh tapes that is saved forever.
+.It
+After a level 0, dumps of active file
+systems are taken on a daily basis,
+using a modified Tower of Hanoi algorithm,
+with this sequence of dump levels:
+.Bd -literal -offset indent
+3 2 5 4 7 6 9 8 9 9 ...
+.Ed
+.Pp
+For the daily dumps, it should be possible to use a fixed number of tapes
+for each day, used on a weekly basis.
+Each week, a level 1 dump is taken, and
+the daily Hanoi sequence repeats beginning with 3.
+For weekly dumps, another fixed set of tapes per dumped file system is
+used, also on a cyclical basis.
+.El
+.Pp
+After several months or so, the daily and weekly tapes should get
+rotated out of the dump cycle and fresh tapes brought in.
+.Sh FILES
+.Bl -tag -width /etc/dumpdates -compact

+.Sh SEE ALSO
+.Xr restore 8 ,
+.Xr rmt 8 ,
+.Xr dump 5 ,
+.Xr fstab 5
+.Sh DIAGNOSTICS
+Many, and verbose.
+.Pp
+Dump exits with zero status on success.
+Startup errors are indicated with an exit code of 1;
+abnormal termination is indicated with an exit code of 3.
+.Sh BUGS
+Fewer than 32 read errors on the filesystem are ignored.
+.Pp
+Each reel requires a new process, so parent processes for
+reels already written just hang around until the entire tape
+is written.
+.Pp
+.Nm Dump
+with the
+.Fl W
+or
+.Fl w
+options does not report filesystems that have never been recorded
+in
+.Pa /etc/dumpdates ,
+even if listed in
+.Pa /etc/fstab .
+.Pp
+It would be nice if
+.Nm dump
+knew about the dump sequence,
+kept track of the tapes scribbled on,
+told the operator which tape to mount when,
+and provided more assistance
+for the operator running
+.Xr restore .
+.Sh HISTORY
+A
+.Nm dump
+command appeared in Version 6 AT&T UNIX.

+.Sh DESCRIPTION
+The
+.Nm restore
+command performs the inverse function of
+.Xr dump 8 .
+A full backup of a file system may be restored and
+subsequent incremental backups layered on top of it.
+Single files and
+directory subtrees may be restored from full or partial
+backups.
+.Nm Restore
+works across a network;
+to do this see the
+.Fl f
+flag described below.
+Other arguments to the command are file or directory
+names specifying the files that are to be restored.
+Unless the
+.Fl h
+flag is specified (see below),
+the appearance of a directory name refers to
+the files and (recursively) subdirectories of that directory.
+.Pp
+Exactly one of the following flags is required:
+.Bl -tag -width Ds
+.It Fl C
+This mode allows comparison of files from a dump.
+.Nm Restore
+reads the backup and compares its contents with files present on the
+disk.
+It first changes its working directory to the root of the filesystem
+that was dumped and compares the tape with the files in its new
+current directory.
+.It Fl i
+This mode allows interactive restoration of files from a dump.
+After reading in the directory information from the dump,
+.Nm restore
+provides a shell like interface that allows the user to move
+around the directory tree selecting files to be extracted.
+The available commands are given below;
+for those commands that require an argument,
+the default is the current directory.
+.Bl -tag -width Fl
+.It Ic add Op Ar arg
+The current directory or specified argument is added to the list of
+files to be extracted.
+If a directory is specified, then it and all its descendents are
+added to the extraction list
+(unless the
+.Fl h
+flag is specified on the command line).
+Files that are on the extraction list are prepended with a ``*''
+when they are listed by
+.Ic ls .
+.It Ic \&cd Ar arg
+Change the current working directory to the specified argument.
+.It Ic delete Op Ar arg
+The current directory or specified argument is deleted from the list of
+files to be extracted.
+If a directory is specified, then it and all its descendents are
+deleted from the extraction list
+(unless the
+.Fl h
+flag is specified on the command line).
+The most expedient way to extract most of the files from a directory
+is to add the directory to the extraction list and then delete
+those files that are not needed.
+.It Ic extract
+All the files that are on the extraction list are extracted
+from the dump.
+.Nm Restore
+will ask which volume the user wishes to mount.
+The fastest way to extract a few files is to
+start with the last volume, and work towards the first volume.
+.It Ic help
+List a summary of the available commands.
+.It Ic \&ls Op Ar arg
+List the current or specified directory.
+Entries that are directories are appended with a ``/''.
+Entries that have been marked for extraction are prepended with a ``*''.
+If the verbose
+flag is set the inode number of each entry is also listed.
+.It Ic pwd
+Print the full pathname of the current working directory.
+.It Ic quit
+Restore immediately exits,
+even if the extraction list is not empty.
+.It Ic setmodes
+All the directories that have been added to the extraction list
+have their owner, modes, and times set;
+nothing is extracted from the dump.
+This is useful for cleaning up after a restore has been prematurely aborted.
+.It Ic verbose
+The sense of the
+.Fl v
+flag is toggled.
+When set, the verbose flag causes the
+.Ic ls
+command to list the inode numbers of all entries.
+It also causes
+.Nm restore
+to print out information about each file as it is extracted.
+.El
+.It Fl R
+.Nm Restore
+requests a particular tape of a multi volume set on which to restart
+a full restore
+(see the
+.Fl r
+flag below).
+This is useful if the restore has been interrupted.
+.It Fl r
+Restore (rebuild a file system).
+The target file system should be made pristine with
+.Xr newfs 8 ,
+mounted and the user
+.Xr cd Ns 'd
+into the pristine file system
+before starting the restoration of the initial level 0 backup. If the
+level 0 restores successfully, the
+.Fl r
+flag may be used to restore
+any necessary incremental backups on top of the level 0.
+The
+.Fl r
+flag precludes an interactive file extraction and can be
+detrimental to one's health if not used carefully (not to mention
+the disk). An example:
+.Bd -literal -offset indent
+newfs /dev/rrp0g eagle
+mount /dev/rp0g /mnt
+cd /mnt
+
+restore rf /dev/rst8
+.Ed
+.Pp
+Note that
+.Nm restore
+leaves a file
+.Pa restoresymtable
+in the root directory to pass information between incremental
+restore passes.
+This file should be removed when the last incremental has been
+restored.
+.Pp
+.Nm Restore ,
+in conjunction with
+.Xr newfs 8
+and
+.Xr dump 8 ,
+may be used to modify file system parameters
+such as size or block size.
+.It Fl t
+The names of the specified files are listed if they occur
+on the backup.
+If no file argument is given,
+then the root directory is listed,
+which results in the entire content of the
+backup being listed,
+unless the
+.Fl h
+flag has been specified.
+Note that the
+.Fl t
+flag replaces the function of the old
+.Xr dumpdir 8
+program.
+.ne 1i
+.It Fl x
+The named files are read from the given media.
+If a named file matches a directory whose contents
+are on the backup
+and the
+.Fl h
+flag is not specified,
+the directory is recursively extracted.
+The owner, modification time,
+and mode are restored (if possible).
+If no file argument is given,
+then the root directory is extracted,
+which results in the entire content of the
+backup being extracted,
+unless the
+.Fl h
+flag has been specified.
+.El
+.Pp
+The following additional options may be specified:
+.Bl -tag -width Ds
+.It Fl b Ar blocksize
+The number of kilobytes per dump record.
+If the
+.Fl b
+option is not specified,
+.Nm restore
+tries to determine the block size dynamically.
+.It Fl c
+Normally,
+.Nm restore
+will try to determine dynamically whether the dump was made from an
+old (pre-4.4) or new format file sytem. The
+.Fl c
+flag disables this check, and only allows reading a dump in the old
+format.
+.It Fl D Ar filesystem
+The
+.Fl D
+flag allows the user to specify the filesystem name when using
+.Nm restore
+with the
+.Fl C
+option to check the backup.
+.It Fl f Ar file
+Read the backup from
+.Ar file ;
+.Ar file
+may be a special device file
+like
+.Pa /dev/rmt12
+(a tape drive),
+.Pa /dev/rsd1c
+(a disk drive),
+an ordinary file,
+or
+.Ql Fl
+(the standard input).
+If the name of the file is of the form
+.Dq host:file ,
+or
+.Dq user@host:file ,
+.Nm restore
+reads from the named file on the remote host using
+.Xr rmt 8 .
+.Pp
+.It Fl h
+Extract the actual directory,
+rather than the files that it references.
+This prevents hierarchical restoration of complete subtrees
+from the dump.
+.It Fl m
+Extract by inode numbers rather than by file name.
+This is useful if only a few files are being extracted,
+and one wants to avoid regenerating the complete pathname
+to the file.
+.It Fl N
+The
+.Fl N
+flag causes
+.Nm restore to only print file names. Files are not extracted.
+.It Fl s Ar fileno
+Read from the specified
+.Ar fileno
+on a multi-file tape.
+File numbering starts at 1.
+.It Fl T Ar directory
+The
+.Fl T
+flag allows the user to specify a directory to use for the storage of
+temporary files. The default value is /tmp. This flag is most useful
+when restoring files after having booted from a floppy. There might be little
+or no space on the floppy filesystem, but another source of space might exist.
+.It Fl v
+Normally
+.Nm restore
+does its work silently.
+The
+.Fl v
+(verbose)
+flag causes it to type the name of each file it treats
+preceded by its file type.
+.It Fl y
+Do not ask the user whether to abort the restore in the event of an error.
+Always try to skip over the bad block(s) and continue.
+.El
+.Sh DIAGNOSTICS
+Complaints if it gets a read error.
+If
+.Fl y
+has been specified, or the user responds
+.Ql y ,
+.Nm restore
+will attempt to continue the restore.
+.Pp
+If a backup was made using more than one tape volume,
+.Nm restore
+will notify the user when it is time to mount the next volume.
+If the
+.Fl x
+or
+.Fl i
+flag has been specified,
+.Nm restore
+will also ask which volume the user wishes to mount.
+The fastest way to extract a few files is to
+start with the last volume, and work towards the first volume.
+.Pp
+There are numerous consistency checks that can be listed by
+.Nm restore .
+Most checks are self-explanatory or can ``never happen''.
+Common errors are given below.
+.Pp
+.Bl -tag -width Ds -compact
+.It Converting to new file system format.
+A dump tape created from the old file system has been loaded.
+It is automatically converted to the new file system format.
+.Pp
+.It <filename>: not found on tape
+The specified file name was listed in the tape directory,
+but was not found on the tape.
+This is caused by tape read errors while looking for the file,
+and from using a dump tape created on an active file system.
+.Pp
+.It expected next file <inumber>, got <inumber>
+A file that was not listed in the directory showed up.
+This can occur when using a dump created on an active file system.
+.Pp
+.It Incremental dump too low
+When doing incremental restore,
+a dump that was written before the previous incremental dump,
+or that has too low an incremental level has been loaded.
+.Pp
+.It Incremental dump too high
+When doing incremental restore,
+a dump that does not begin its coverage where the previous incremental
+dump left off,
+or that has too high an incremental level has been loaded.
+.Pp
+.It Tape read error while restoring <filename>
+.It Tape read error while skipping over inode <inumber>
+.It Tape read error while trying to resynchronize
+A tape (or other media) read error has occurred.
+If a file name is specified,
+then its contents are probably partially wrong.
+If an inode is being skipped or the tape is trying to resynchronize,
+then no extracted files have been corrupted,
+though files may not be found on the tape.
+.Pp
+.It resync restore, skipped <num> blocks
+After a dump read error,
+.Nm restore
+may have to resynchronize itself.
+This message lists the number of blocks that were skipped over.
+.El
+.Sh FILES
+.Bl -tag -width "./restoresymtable" -compact
+.It Pa /dev/rmt?
+the default tape drive
+.It Pa /tmp/rstdir*
+file containing directories on the tape.
+.It Pa /tmp/rstmode*
+owner, mode, and time stamps for directories.
+.It Pa \&./restoresymtable
+information passed between incremental restores.

+.Sh BUGS
+.Nm Restore
+can get confused when doing incremental restores from
+dumps that were made on active file systems.
+.Pp
+A level zero dump must be done after a full restore.
+Because restore runs in user code,
+it has no control over inode allocation;
+thus a full dump must be done to get a new set of directories
+reflecting the new inode numbering,
+even though the contents of the files is unchanged.

+.Sh NAME
+.Nm rmt
+.Nd remote magtape protocol module
+.Sh SYNOPSIS
+.Nm rmt
+.Sh DESCRIPTION
+.Nm Rmt
+is a program used by the remote dump and restore programs
+in manipulating a magnetic tape drive through an interprocess
+communication connection.
+.Nm Rmt
+is normally started up with an
+.Xr rexec 3
+or
+.Xr rcmd 3
+call.
+.Pp
+The
+.Nm rmt
+program accepts requests specific to the manipulation of
+magnetic tapes, performs the commands, then responds with
+a status indication. All responses are in
+.Tn ASCII
+and in
+one of two forms.
+Successful commands have responses of:
+.Bd -filled -offset indent
+.Sm off
+.Sy A Ar number No \en
+.Sm on
+.Ed
+.Pp
+.Ar Number
+is an
+.Tn ASCII
+representation of a decimal number.
+Unsuccessful commands are responded to with:
+.Bd -filled -offset indent
+.Sm off
+.Xo Sy E Ar error-number
+.No \en Ar error-message
+.No \en
+.Xc
+.Sm on
+.Ed
+.Pp
+.Ar Error-number
+is one of the possible error
+numbers described in
+.Xr intro 2
+and
+.Ar error-message
+is the corresponding error string as printed
+from a call to
+.Xr perror 3 .
+The protocol is comprised of the
+following commands, which are sent as indicated - no spaces are supplied
+between the command and its arguments, or between its arguments, and
+.Ql \en
+indicates that a newline should be supplied:
+.Bl -tag -width Ds
+.Sm off
+.It Xo Sy \&O Ar device
+.No \en Ar mode No \en
+.Xc
+Open the specified
+.Ar device
+using the indicated
+.Ar mode .
+.Ar Device
+is a full pathname and
+.Ar mode
+is an
+.Tn ASCII
+representation of a decimal
+number suitable for passing to
+.Xr open 2 .
+If a device had already been opened, it is
+closed before a new open is performed.
+.It Xo Sy C Ar device No \en
+.Xc
+Close the currently open device. The
+.Ar device
+specified is ignored.
+.It Xo Sy L
+.Ar whence No \en
+.Ar offset No \en
+.Xc
+.Sm on
+Perform an
+.Xr lseek 2
+operation using the specified parameters.
+The response value is that returned from the
+.Xr lseek
+call.
+.Sm off
+.It Sy W Ar count No \en
+.Sm on
+Write data onto the open device.
+.Nm Rmt
+reads
+.Ar count
+bytes from the connection, aborting if
+a premature end-of-file is encountered.
+The response value is that returned from
+the
+.Xr write 2
+call.
+.Sm off
+.It Sy R Ar count No \en
+.Sm on
+Read
+.Ar count
+bytes of data from the open device.
+If
+.Ar count
+exceeds the size of the data buffer (10 kilobytes), it is
+truncated to the data buffer size.
+.Nm rmt
+then performs the requested
+.Xr read 2
+and responds with
+.Sm off
+.Sy A Ar count-read No \en
+.Sm on
+if the read was
+successful; otherwise an error in the
+standard format is returned. If the read
+was successful, the data read is then sent.
+.Sm off
+.It Xo Sy I Ar operation
+.No \en Ar count No \en
+.Xc
+.Sm on
+Perform a
+.Dv MTIOCOP
+.Xr ioctl 2
+command using the specified parameters.
+The parameters are interpreted as the
+.Tn ASCII
+representations of the decimal values
+to place in the
+.Ar mt_op
+and
+.Ar mt_count
+fields of the structure used in the
+.Xr ioctl
+call. The return value is the
+.Ar count
+parameter when the operation is successful.
+.ne 1i
+.It Sy S
+Return the status of the open device, as
+obtained with a
+.Dv MTIOCGET
+.Xr ioctl
+call. If the operation was successful,
+an ``ack'' is sent with the size of the
+status buffer, then the status buffer is
+sent (in binary).
+.El
+.Sm on
+.Pp
+Any other command causes
+.Nm rmt
+to exit.
+.Sh DIAGNOSTICS
+All responses are of the form described above.
+.Sh SEE ALSO
+.Xr rcmd 3 ,
+.Xr rexec 3 ,
+.Xr mtio 4 ,
+.Xr rdump 8 ,
+.Xr rrestore 8
+.Sh BUGS
+People should be discouraged from using this for a remote
+file access protocol.
+.Sh HISTORY
+The
+.Nm
+command appeared in
+.Bx 4.2 .
