smbtar - shell script for backing up SMB shares directly to UNIX tape drive
smbtar -s server [ -p password ] [ -x service ] [ -u user ] [ -t tape ] [ -b blocksize ] [ -n filename ] [ -i ] [ -r ] [ -l ]
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.
-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).
The TAPE variable specifies the default tape device to write to. May be overidden with the -t option.
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.
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.
This man page is correct for version 1.9.02 of the Samba suite.
See diagnostics for smbclient command.
