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 samba(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           Reset DOS archive bit mode to indicate file has been archived.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. 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 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.

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.
