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       Reset DOS archive bit mode to indicate file has been archived.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

VERSION

   This man page is correct for version 3 of the Samba suite.

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.
