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          Reset DOS archive bit mode to indicate file has been archived.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

       -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 ar-
          chive 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 smb-
       client'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 3.0 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 excel-
       lent     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.
