<title>ENVIRONMENT VARIABLES</title>
167
<para>The <parameter>$TAPE</parameter> variable specifies the
168
default tape device to write to. May be overridden
169
with the -t option. </para>
176
<para>The <command>smbtar</command> script has different
177
options from ordinary tar and from smbclient's tar command. </para>
182
<title>CAVEATS</title>
184
<para>Sites that are more careful about security may not like
185
the way the script handles PC passwords. Backup and restore work
186
on entire shares; should work on file lists. smbtar works best
187
with GNU tar and may not work well with other versions. </para>

219
<para>The original Samba software and related utilities
220
were created by Andrew Tridgell. Samba is now developed
221
by the Samba Team as an Open Source project similar
222
to the way the Linux kernel is developed.</para>

<para><ulink noescape="1" url="mailto:poultenr@logica.co.uk">Ricky Poulten</ulink>
225
wrote the tar extension and this man page. The <command>smbtar</command>
226
script was heavily rewritten and improved by <ulink noescape="1"
227
url="mailto:Martin.Kraemer@mch.sni.de">Martin Kraemer</ulink>. Many
228
thanks to everyone who suggested extensions, improvements, bug
229
fixes, etc. The man page sources were converted to YODL format (another
230
excellent piece of Open Source software, available at <ulink noescape="1" url="ftp://ftp.icce.rug.nl/pub/unix/">
231
ftp://ftp.icce.rug.nl/pub/unix/</ulink>) and updated for the Samba 2.0
232
release by Jeremy Allison. The conversion to DocBook for
233
Samba 2.2 was done by Gerald Carter. The conversion to DocBook XML 4.2 for
234
Samba 3.0 was done by Alexander Bokovoy.</para>
