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. diff --git a/COPYRIGHT b/COPYRIGHT new file mode 100644 index 0000000..ce4bd12 --- /dev/null +++ b/COPYRIGHT @@ -0,0 +1,39 @@ +/* + * Ported to Linux's Second Extended File System as part of the + * dump and restore backup suit + * Remy Card , 1994, 1995 + * + */ + +/*- + * Copyright (c) 1980, 1993 + * The Regents of the University of California.

+.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 +.It Pa /dev/rmt8 +default tape unit to dump to +.It Pa /etc/dumpdates +dump date records +.It Pa /etc/fstab +dump table: file

+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 : 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 , got +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 +.It Tape read error while skipping over inode +.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 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. +.El +.Sh SEE ALSO +.Xr dump 8 , +.Xr newfs 8 , +.Xr mount 8 , +.Xr mkfs 8 , +.Xr rmt 8 +.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 HISTORY +The +.Nm restore +command appeared in +.Bx 4.2 . diff --git a/restore/restore.c b/restore/restore.c new file mode 100644 index 0000000..533ae5b --- /dev/null +++ b/restore/restore.c @@ -0,0 +1,952 @@ +/* + * Ported to Linux's Second Extended File System as part of the + * dump and restore backup suit + * Remy Card , 1994, 1995, 1996 + * + */ + +/* + * Copyright (c) 1983, 1993 + * The Regents of the University of California.
