Currently, we are dumping the Solaris clients using
Amanda from the Ptolemy cluster dumphost, which
is currently <code>maury</code>
<p>We use amanda, the documentation can be found at
<a href="http://ptolemy.eecs.berkeley.edu/~cxh/sa/dumps.html"><code>http://ptolemy.eecs.berkeley.edu/~cxh/sa/dumps.html</code></a>
which corresponds to <code>/home/eecs/cxh/public_html/sa/dumps.html</code>

<p>We do dumps every night, and get a level 0
dump of each machine every two weeks.

<p>Twice a year, we do two sets of level 0 backups,
one of which we give to Brad for storage offsite
at <a href="http://w3.arcusds.com/">Arcus Data Security</a>, 
phone 510.489.5100. 
PO Box 326, Union City, CA
(Arcus is now called Iron Mountain)

<p>Any software that is in a CVS repository can
also be found on the laptops of offsite users.
This makes it much easier to recover the current
state of the PHP and JSP pages that run the website.

<h3>Restoring by hand</h3>
Each dump is stored on the tape as a separate tape file.
One of the first files should be a table of contents
listing file systems that are on the tape.
<br>Each dump is stored compressed using gzip.
<br>Use <CODE>mt</CODE> to advance the tape and try using dd to
dump the tape file to a disk file:

<pre>
mt -f /dev/nrst19 fsf 83
dd if=/dev/nrst19 bs=32k  > galileo1
</pre>


Then to restore, do:
<pre>
cd /x/restore
dd if=/export/maury/maury4/amanda/galileo1 bs=32k skip=1 | /users/dumper/bin/gzip -dc |/usr/sbin/ufsrestore -fi -

</pre>
