<para>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. </para>

<title>AUTHOR</title>
<para>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.</para>
<para><ulink noescape="1" url="mailto:poultenr@logica.co.uk">Ricky Poulten</ulink>
wrote the tar extension and this man page. The <command>smbtar</command>
script was heavily rewritten and improved by <ulink noescape="1"
url="mailto:Martin.Kraemer@mch.sni.de">Martin Kraemer</ulink>. 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 <ulink noescape="1" url="ftp://ftp.icce.rug.nl/pub/unix/">
ftp://ftp.icce.rug.nl/pub/unix/</ulink>) 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.</para>
