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	   Reset DOS archive bit mode to indicate file has been archived.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