.SH "NAME"
/etc/flexbackup.conf \- a flexible backup/archiving tool configuration file
.SH "DESCRIPTION"
Flexbackup configuration file. Check \fBflexbackup\fR(1) or
\(dq\fBflexbackup\fR \fI-help\fR\(dq for usage information.

General Configuration Settings
.RS
.TP
\fB$type\fR = \fI'afio'\fI;
Which archive type to use.  Supported types are: \fBafio\fR(1), \fBdump\fR(1),
\fBtar\fR(1), \fBcpio\fR(1), \fBstar\fR(1), \fBpax\fR(1), \fBzip\fR(1),
\fBlha\fR(1), \fBar\fR(1), \fBshar\fR(1). \fI'copy'\fR is another option if
running in archive-to-disk mode.  Use \fI'filelist'\fR to dump a list of files
in your cwd - for debugging setup/exclusion.
.TP
\fB$set{\fI'tag'\fR}\fR = \fI'/dir'\fR;
Configure backup \(dqsets\(dq. Not needed if \(dq-dir <dir>\(dq is used to
backup one tree at a time.  Each set is a simple space-separated list of
filesystems/directories. Remote filesystems should be denoted as
\(dqhost:directory\(dq.  You can use anything (other than \fI'all'\fR) as set
names. Using \(dq-set all\(dq will back up all defined sets. If you are doing
a full backup using tapes, each \(dqset\(dq will go onto a different tape and
you will be prompted for tape change in between. Examples:
.RS
.PP
\fB$set{\fI'set1'\fI}\fR = \fI'/home /usr'\fR;
.br
\fB$set{\fI'set2'\fI}\fR = \fI'/dir3 machine2:/dir4 machine3:/dir5'\fR;
.RE
.TP
\fB$prune{\fI'/'\fR}\fR = \fI'tmp proc'\fR;
Configure subtree pruning. A space-separated list of directories to prune from
each backup. Key is a filesystem/directory or \(dqhost:directory\(dq spec as
outlined above regular expressions allowed (not shell-type wildcards!).
.TP
\fB$compress\fR = \fI'false|gzip|bzip2|lzop|zip|compress|hardware|lzma'\fR;
.TQ
\fB$compr_level\fR = \fI'4'\fR;
Configure compression. Choose a type of compression to use and configure the
level.  The compression level only applies to \fIgzip/bzip2/lzop/zip\fR compression
types.
.TP
\fB$buffer\fR = \fI'false|buffer|mbuffer'\fR;
.TQ
\fB$buffer_megs\fR = \fI'10'\fR;
.TQ
\fB$buffer_fill_pct\fR = \fI'75'\fR;
.TQ
\fB$buffer_pause_usec\fR = \fI'100'\fR;
Configure buffering program to help streaming to tapes. Specify the buffer
memory size in \fB$buffer_megs\fR, how full buffer needs to be to start writing
in \fB$buffer_fill_pct\fR, and how long to sleep after every write (which helps
sustain stream bursts) in \fB$buffer_pause_usec\fR.
.TP
\fB$device\fR = \fI'/dev/tape'\fR;
Configure device to backup to. \fBNon-rewinding version, please!\fR. If the
target is a directory, \fBflexbackup\fR will archive to files in that directory
rather than to a device.  If configured as \(dqhost:/dev/tapedevice\(dq, will
use remote tape drive via rsh/ssha.  Examples:
.TS
afCW s l.
_
Linux SCSI w/devfs:	/dev/tapes/tape0/mtn
Linux SCSI:	/dev/nst0
Linux IDE:	/dev/nht0
Linux ftape:	/dev/nqft0
FreeBSD SCSI:	/dev/nrsa0
_
.TE
.TP
\fB$blksize\fR = \fI'10'\fR;
Configure the block size (in kilobytes!) to use for archive programs and dd.
Default is IfB10\fR for most things. Some tape drives need \fI32\fR or \fI64\fR.
Set to \fI'0'\fR to disable all blocking.
.TP
\fB$mt_blksize\fR = \fI'0'\fR;
Configure the block size (in bytes!) to use for the tape device, with
\(dqmt setblk\(dq or equivalent. If set to \fI'0'\fR, will use \(dqvariable\(dq
block size for the tape device (which is recommended). Comment out or set to
\(dq\fB$blksize\fR * 1024\(dq to have it be the same as the archiver block size
above.
.TP
\fB$pad_blocks\fR = \fI'true|false'\fR;
Configure block padding.  True to pad blocks to blocksize (devices only, not
used when archiving to files).
.TP
\fB$mt{\fI'command'\fR}\fR = \fI'other'\fR;
Configure \fBmt\fR operation overrides. Set these if \fBflexbackup\fR doesn't
know the right \fBmt\fR command(s) for your OS/tape device, or you want to
override things. Example:
.RS
.TP
Use \fB\(dqmt \fIstatus\fR\(dq\fR instead of \fB\(dqmt \fItell\fR\(dq\fR
\fB$mt{\fI'tell'\fR}\fR = \fI'status'\fR;
.RE

Other Global Settings
.RS
.TP
\fB$remoteshell\fR = \fI'rsh|ssh|ssh2'\fR;
Configure the command to use for remote shell.
.TP
\fB$remoteuser\fR = \fI''\fR;
If not empty (or not set), the secondary username for remote shells.
.TP
\fB$label\fR = \fI'true|false'\fR;
Somehow store identifying label in archive?
.TP
\fB$verbose\fR = \fI'true|false'\fR;
Print each file?
.TP
\fB$sparse\fR = \fI'true|false'\fR;
Handle sparse files?
.TP
\fB$indexes\fR = \fI'true|false'\fR;
Set to \fI'false'\fR to turn off all table-of-contents support.
.TP
\fB$staticfiles\fR = \fI'true|false'\fR;
If backing up to files, use static filenames \- no date stamp (same level
backup of same directory will overwrite old backups).
.TP
\fB$atime_preserve\fR = \fI'true|false'\fR;
Set to true to try and preserve file access times during backup, if the
selected archive program can do so. Note that if this is true, \-cnewer checks
(file permission/status changes only, not content) are turned off when deciding
which files to archive on the local system.
.TP
\fB$traverse_fs\fR = \fI'false|local|all'\fR;
Span across filesytems? (backups of type \fB'dump'\fR will ignore this option).
Set to \fI'false'\fR (don't), \fI'local'\fR (all but nfs/smbfs), or \fI'all'\fR
(everything)
.TP
\fB$exclude_expr[\fI0\fR]\fR = \fI'.*'\fR;
Exclude files that match these \fBregular expressions\fR (not shell wildcards)
from the backups (backups of type \fB'dump'\fR will ignore this option). You
can list more than one, just keep incrementing the index in the brackets for
each. Also, strip off leading directories (the filesystem specs above or the
\(dq-dir\(dq flag).  Matches paths, not filenames, so put .* on the front/back
as needed. Examples:
.RS
.PP
\fB$exclude_expr[\fI0\fR]\fR = \fI'.*/[Cc]ache/.*'\fR;
.br
\fB$exclude_expr[\fI1\fR]\fR = \fI'.*~$'\fR;
.RE
.TP
\fB$erase_tape_set_level_zero\fR = \fI'true|false'\fR;
If set to true (default), and using a tape device, level 0 (full) \(dqset\(dq
backup types assume you want to erase and use a new tape for each set. If
set to false, level 0 (full) \(dqset\(dq backup types append to tapes. To force
an erase for any backup, use \fI\(dq-erase\(dq\fR on the command-line.
.TP
\fB$erase_rewind_only\fR = \fI'true|false'\fR;
Set this to \fB'true'\fR to make erase operations just call \fB\(dqmt
\fIrewind\fR\(dq\fR - not \fB\(dqmt rewind\(dq\fR followed by \fB\(dqmt
\fIerase\fR\(dq\fR.
(For some tape drives, erase takes hours rather than seconds or is otherwise
undesirable).

Log, Stamps, and Binary Location Settings
.RS
.TP
\fB$logdir\fR = \fI'/var/log/flexbackup'\fR;
Directory for log files.
.TP
\fB$comp_log\fR = \fI'false|gzip|bzip2|lzop|compress|zip'\fR;
Compress log?
.TP
\fB$staticlogs\fR = \fI'true|false'\fR;
Use static log filenames with no date stamp?
.TP
\fB$prefix\fR = \fI''\fR;
Log filenames will start with this prefix.
.TP
\fB$tmpdir\fR = \fI'/tmp'\fR;
Used for temporary refdate files, etc.
.TP
\fB$stampdir\fR = \fI'/var/lib/flexbackup'\fR;
Directory for backup timestamp files.
.TP
\fB$index\fR = \fI'/var/lib/flexbackup/index'\fR;
Full path (without the .db extension) to the database filename for tape indexes.
.TP
\fB$keyfile\fR = \fI'00-index-key'\fR;
Filename for keyfile if archiving to dir.
.TP
\fB$sprefix\fR = \fI''\fR;
Stamp filenames will start with this prefix.
.TP
\fB$path{\fI'program'\fR}\fR = \fI'/path/to/program'\fR;
Override paths to commands. By default \fBflexbackup\fR will look for them in
\fI$PATH\fR. Use this if you want to set commands explicitly. You can use full
paths or just change command names. Examples:
.RS
.TP
If GNU \fBtar\fR is called \fB\(dqgtar\(dq\fR on your system:
\fB$path{'tar'} = 'gtar';
.TP
Or it can be used to \fB\(dqsudo\(dq\fR certain commands:
\fB$path{\fI'find'\fR}\fR = \fI'sudo find'\fR;
.br
\fB$path{\fI'dump'\fR}\fR = \fI'sudo dump'\fR;

Specific Command Settings
.RS
.TP
\fB$afio_nocompress_types\fR = \fI'ext1 ext2 ...'\fR;
.TQ
\fB$afio_echo_block\fR = \fI'true|false'\fR;
.TQ
\fB$afio_compress_threshold\fR = \fI'3'\fR;
.TQ
\fB$afio_compress_cache_size\fR = \fI'2'\fR;
These settings apply to the \fB'afio'\fR backup types only. In addition to the
afio defaults, files with extensions specified in \fB$afio_nocompress_types\fR
will not be compressed.  Define whether or not echo block numbers in
\fB$afio_echo_block\fR. Configure the minimum file size (in kilobytes) required
for compression in \fB$afio_compress_threshold\fR.
\fB$afio_compress_cache_size\fR setting is used to specify the maximum amount
of memory (megabytes) to use for temporary storage of compression results. If a
compressed file is bigger than this, compression will have to run twice on the
file. See the \fBafio\fR(1) manpage for more information.
.TP
\fB$tar_echo_record_num\fR = \fI'true|false'\fR;
These settings apply to the \fB'tar'\fR backup types only. Define whether
or not echo record numbers in \fB$tar_echo_record_num\fR.
.TP
\fB$cpio_format\fR = \fI'newc'\fR;
These settings apply to the \fB'cpio'\fR backup types only. Configure the
format of the archive in \fB$cpio_format\fR. See the \fBcpio\fR(1) manpage for
allowed formats.
.TP
\fB$dump_length\fR = \fI'0'\fR;
.TQ
\fB$dump_use_dumpdates\fR = \fI'true|false'\fR;
These settings apply to the \fB'dump'\fR backup types only. Configure the
estimated tape size (in kilobytes) using the \fB$dump_length\fR setting. This
number doesn't really do much but help \fBdump\fR get size estimates if set to
0, \fBflexbackup\fR uses \fB'dump \fI-a\fR'\fR to determine this. Set
\fB$dump_use_dumpdates\fR setting to \fI'true\fR to use \fB/etc/dumpdates\fR
(could mess things up if you dump subdirectories of mount points). Set it to
\fI'false'\fR to use \fBflexbackup\fR's internal timestamps.
.TP
\fB$star_fifo\fR = \fI'true|false'\fR;
.TQ
\fB$star_acl\fR = \fI'true|false'\fR;
.TQ
\fB$star_echo_block_num\fR = \fI'true|false'\fR;
.TQ
\fB$star_format\fR = \fI'exustar'\fR;
These settings apply to the \fB'star'\fR backup types only. Define whether
or not use fifo (buffering) in \fB$star_fifo\fR.  If you set this to
\fB'true'\fR you probably want to set \fB$buffer\fB = \fI'false'\fR (see above).
Configure whether or not to handle ACLs in \fB$star_acl\fR.  Define whether or
not echo record numbers in \fB$star_echo_block_num\fR. Configure the format of
the archive in \fB$star_format\fR. See the \fBstar\fR(1) manpage for allowed
formats.
.TP
\fB$pax_format\fR = \fI'ustar'\fR;
These settings apply to the \fB'pax'\fR backup types only. Configure the
format of the archive in \fB$pax_format\fR. See the \fBpax\fR(1) manpage for
allowed formats.
.TP
\fB$zip_nocompress_types\fR = \fI'ext1 ext2 ...'\fR;
These settings apply to the \fB'zip'\fR backup types only. Files with
extensions specified in \fB$zip_nocompress_types\fR will not be compressed.
.TP
\fB$pkgdelta_archive_list\fR = \fI'true|false|rootonly'\fR;
.TQ
\fB$pkgdelta_archive_unowned\fR = \fI'true|false'\fR;
.TQ
\fB$pkgdelta_archive_changed\fR = \fI'true|false'\fR;
These settings apply to the \fB'pkgdelta'\fR backup types only.
Configure whether to archive a list of all installed packages in the top level
of each backup in \fB$pkgdelta_archive_list\fR. Can be \fI'false'\fR (don't),
\fI'true'\fR (save it for any backup), or \fI'rootonly'\fR (saves list only if
the filesystem is \fI'/'\fR). Define whether or not to archive files not
\(dqowned\(dq by any package in \fB$pkgdelta_archive_unowned\fR. Specify whether
or not to archive any package-owned files which have been modified in
\fB$pkgdelta_archive_changed\fR.
