smbtar - shell script for backing up SMB/CIFS shares directly to UNIX
smbtar -s server [ -p password ] [ -x services ] [ -X ] [ -d direc-
tory ] [ -u user ] [ -t tape ] [ -t tape ] [ -b blocksize ] [ -N
filename ] [ -i ] [ -r ] [ -l loglevel ] [ -v ] filenames
This tool is part of the Samba suite.
smbtar is a very small shell script on top of smbclient(1) which dumps
SMB shares directly to tape.
The SMB/CIFS server that the share resides upon.
The share name on the server to connect to. The default is
-X Exclude mode. Exclude filenames... from tar create or restore.
Change to initial directory before restoring / backing up files.
-v Verbose mode.
The password to use to access a share. Default: none
The user id to connect as. Default: UNIX login name.
Tape device. May be regular file or tape device. Default: $TAPE
environmental variable; if not set, a file called tar.out .
Blocking factor. Defaults to 20. See tar(1) for a fuller expla-
Backup only files newer than filename. Could be used (for exam-
ple) 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
-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) .
The $TAPE variable specifies the default tape device to write to. May
be overridden with the -t option.
The smbtar script has different options from ordinary tar and tar
called from smbclient.
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.

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 <URL:mailto:firstname.lastname@example.org> wrote the tar exten-
sion and this man page. The smbtar script was heavily rewritten and
improved by Martin Kraemer <URL:mailto:Martin.Kraemer@mch.sni.de>. Many
thanks to everyone who suggested extensions, improvements, bug fixes,
etc. The man page sources were converted to YODL format (another excel-
lent piece of Open Source software, available at
and updated for the Samba 2.0 release by Jeremy Allison. The conversion
to DocBook for Samba 2.2 was done by Gerald Carter.
