SMBTAR(1)

NAME
smbtar - shell script for backing up SMB shares directly to UNIX tape drive

SYNOPSIS
smbtar -s server [ -p password ] [ -x service ] [ -u user ] [ -t tape ] [ -b blocksize ] [ -n filename ] [ -i ] [ -r ] [ -l ]

DESCRIPTION
This program is an extension to 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 PC that the share resides upon.
-x service
    The share name on the PC to connect to. Default: backup.
-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. This flag should not be used with the -i flag, the results may not be sensible.
-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. This flag should not be used with the -n flag, the results may not be sensible.
-r
    Restore. Files are restored to the share from the tar file.
-l
    Debug level. Corresponds to -d flag on smbclient(1).

ENVIRONMENT VARIABLES
The TAPE variable specifies the default tape device to write to. May be overidden with the -t option.

BUGS
The shell script has only been tested under solaris 2. It's not very portable and should probably be customized to a particular site's setup.

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.

VERSION
This man page is correct for version 1.9.02 of the Samba suite.
