NAME
smbtar - shell script for backing up SMB/CIFS shares
directly to UNIX tape drives
SYNOPSIS
- smbtar [-r] [-i] [-a] [-v] {-s server}
[-p password] [-x services] [-X] [-N filename]
[-b blocksize] [-d directory] [-l loglevel]
[-u user] [-t tape] {filenames}
DESCRIPTION
- This tool is part of the (7)
suite.
smbtar is a very small shell script on top of smbclient(1)
which dumps SMB shares directly to tape.
OPTIONS
- -s server
- The SMB/CIFS server that the share resides upon.
- -x service
- The share name on the server to connect to. The default is
"backup".
- -X
- Exclude mode. Exclude filenames... from tar create or restore.
- -d directory
- Change to initial directory before restoring / backing
up files.
- -v
- Verbose mode.
- -p password
- The password to use to access a share. Default: none
- -u user
- The user id to connect as. Default: UNIX login name.
- -a
- Reset DOS archive bit mode to indicate file has been archived.
- -t tape
- Tape device. May be regular file or tape device. Default:
$TAPE environmental variable; if not set, a file called
tar.out .
- -b blocksize
- Blocking factor. Defaults to 20. Seetar(1) for a
fuller explanation.
- -N filename
- Backup only files newer than filename. Could be used (for
example) on a log file to implement incremental backups.
- -i
- Incremental mode; tar files are only backed up if they have the
archive bit set. The archive bit is reset after each file is read.
- -r
- Restore. Files are restored to the share from the tar file.
- -l log level
- Log (debug) level. Corresponds to the-d flag of
smbclient(1).
ENVIRONMENT VARIABLES
The $TAPE variable specifies the default tape device to
write to. May be overridden with the -t option.
BUGS
The smbtar script has different options from ordinary tar
and from smbclient's tar command.
CAVEATS
Sites that are more careful about security may not like the way
the script handles PC passwords. Backup and restore work on entire
shares; should work on file lists. smbtar works best with GNU tar
and may not work well with other versions.
DIAGNOSTICS
See the DIAGNOSTICS section for the smbclient(1)
command.
VERSION

AUTHOR
The original Samba software and related utilities were created
by Andrew Tridgell. Samba is now developed by the Samba Team as an
Open Source project similar to the way the Linux kernel is
developed.
Ricky Poulten wrote the tar extension and this man page. The
smbtar script was heavily rewritten and improved by Martin
Kraemer. Many thanks to everyone who suggested extensions,
improvements, bug fixes, etc. The man page sources were converted
to YODL format (another excellent piece of Open Source software,
available at ftp://ftp.icce.rug.nl/pub/unix/)
and updated for the Samba 2.0 release by Jeremy Allison. The
conversion to DocBook for Samba 2.2 was done by Gerald Carter. The
conversion to DocBook XML 4.2 for Samba 3.0 was done by Alexander
Bokovoy.
