SMBTAR(1)

NAME
smbtar - shell script for backing up SMB/CIFS shares directly to UNIX tape drives

SYNOPSIS

smbtar -s server [-p password] [-x service] [-X] [-d directory] [-u user] [-t tape] [-b blocksize] [-N filename] [-i] [-r] [-l log level] [-v] filenames

DESCRIPTION

This program is part of the Samba suite.

smbtar is a very small shell script on top of smbclient 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.

-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. See tar (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 tar called from smbclient.

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.

VERSION

This man page is correct for version 2.0 of the Samba suite.

AUTHOR

The original Samba software and related utilities were created by Andrew Tridgell samba-bugs@samba.org. Samba is now developed by the Samba Team as an Open Source project similar to the way the Linux kernel is developed.

Ricky Poulten poultenr@logica.co.uk wrote the tar extension and this man page. The smbtar script was heavily rewritten and improved by Martin Kraemer 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 excellent piece of Open Source software available at ftp://ftp.icce.rug.nl/pub/unix/) and updated for the Samba2.0 release by Jeremy Allison, samba-bugs@samba.org.
