24 the way the script handles PC passwords. Backup and restore work
25 on entire shares; should work on file lists. smbtar works best
26 with GNU tar and may not work well with other versions. </p></div><div class="refsect1" lang="en"><a name="id2488470"></a><h2>DIAGNOSTICS</h2><p>See the <span class="emphasis"><em>DIAGNOSTICS</em></span> section for the <a href="smbclient.1.html"><span class="citerefentry"><span class="refentrytitle">smbclient</span>(1)</span></a> command.</p></div><div class="refsect1" lang="en"><a name="id2488493"></a><h2>VERSION</h2><p>This man page is correct for version 3.0 of
