<p><br><a name="DESCRIPTION"></a>
<h2>DESCRIPTION</h2>
    
<p><br>This program is part of the <strong>Samba</strong> suite.
<p><br><strong>smbtar</strong> is a very small shell script on top of
<a href="smbclient.1.html"><strong>smbclient</strong></a> which dumps SMB shares directly
to tape.
<p><br><a name="OPTIONS"></a>
<h2>OPTIONS</h2>
    
<p><br><ul>
<p><br><a name="minuss"></a>
<li><strong><strong>-s server</strong></strong> The SMB/CIFS server that the share resides upon.
<p><br><a name="minusx"></a>
<li><strong><strong>-x service</strong></strong> The share name on the server to connect
to. The default is <code>backup</code>.
<p><br><a name="minusX"></a>
<li><strong><strong>-X</strong></strong> Exclude mode. Exclude filenames... from tar create or
restore.
<p><br><a name="minusd"></a>
<li><strong><strong>-d directory</strong></strong> Change to initial <em>directory</em> before restoring
/ backing up files.
<p><br><a name="minusv"></a>
<li><strong><strong>-v</strong></strong> Verbose mode.
<p><br><a name="minusp"></a>
<li><strong><strong>-p password</strong></strong> The password to use to access a share. Default:
none
<p><br><a name="minusu"></a>
<li><strong><strong>-u user</strong></strong> The user id to connect as. Default: UNIX login name.
<p><br><a name="minust"></a>
<li><strong><strong>-t tape</strong></strong> Tape device. May be regular file or tape
device. Default: <em>TAPE</em> environmental variable; if not set, a file
called <code>tar.out</code>.
<p><br><a name="minusb"></a>
<li><strong><strong>-b blocksize</strong></strong> Blocking factor. Defaults to 20. See <strong>tar (1)</strong>
for a fuller explanation.
<p><br><a name="minusN"></a>
<li><strong><strong>-N filename</strong></strong> Backup only files newer than filename. Could be
used (for example) on a log file to implement incremental backups.
<p><br><a name="minusi"></a>
<li><strong><strong>-i</strong></strong> 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.
<p><br><a name="minusr"></a>
<li><strong><strong>-r</strong></strong> Restore. Files are restored to the share from the tar
file.
<p><br><a name="minusl"></a>
<li><strong><strong>-l log level</strong></strong> Log (debug) level. Corresponds to the
<a href="smbclient.1.html#minusd"><strong>-d</strong></a> flag of <a href="smbclient.1.html"><strong>smbclient
(1)</strong></a>.
<p><br></ul>
<p><br><a name="ENVIRONMENTVARIABLES"></a>
<h2>ENVIRONMENT VARIABLES</h2>
    
<p><br>The TAPE variable specifies the default tape device to write to. May
be overridden with the <a href="smbtar.1.html#minust"><strong>-t</strong></a> option.
<p><br><a name="BUGS"></a>
<h2>BUGS</h2>
    
<p><br>The <strong>smbtar</strong> script has different options from ordinary tar and tar
called from <a href="smbclient.1.html"><strong>smbclient</strong></a>.
<p><br><a name="CAVEATS"></a>
<h2>CAVEATS</h2>
    
<p><br>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. <strong>smbtar</strong> works best with GNU tar and may
not work well with other versions.
<p><br><a name="VERSION"></a>
<h2>VERSION</h2>
    
<p><br>This man page is correct for version 2.0 of the Samba suite.

<h2>AUTHOR</h2>
    
<p><br>The original Samba software and related utilities were created by
Andrew Tridgell <a href="mailto:samba-bugs@samba.org"><em>samba-bugs@samba.org</em></a>. Samba is now developed
by the Samba Team as an Open Source project similar to the way the
Linux kernel is developed.
<p><br>Ricky Poulten <a href="mailto:poultenr@logica.co.uk"><em>poultenr@logica.co.uk</em></a> wrote the tar extension and
this man page. The <strong>smbtar</strong> script was heavily rewritten and
improved by Martin Kraemer <a href="mailto:Martin.Kraemer@mch.sni.de"><em>Martin.Kraemer@mch.sni.de</em></a>. 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
<a href="ftp://ftp.icce.rug.nl/pub/unix/"><strong>ftp://ftp.icce.rug.nl/pub/unix/</strong></a>)
and updated for the Samba2.0 release by Jeremy Allison,
<a href="mailto:samba-bugs@samba.org"><em>samba-bugs@samba.org</em></a>.
