<p>Implement a range of predictive algorithms (and perhaps design your own)

and profile them for power usage and performance loss. The best

algorithm will save the most power while losing the least performance. This

has been discussed on the <a href="acpi@FreeBSD.org">ACPI</a> mailing

list and &a.bruno; has some early patches.</p>

<h2>Write a NDMP data server</h2>
|
||||
<p><strong>URL</strong>: <a
|
||||
href="http://www.ndmp.org/">The NDMP Initiative</a></p>
|
||||
<p>The NDMP initiative was launched to create an open
|
||||
standard protocol for network-based backup for network-attached storage.
|
||||
Major commercial storage systems come with a compliant service. This allows
|
||||
major commercial backup systems to backup such NAS devices. Including a NDMP
|
||||
disk server into FreeBSD would allow to play nice out of the box (modulo some
|
||||
configuring) regarding backups in a corporate environment.</p>
|
||||
<ul>
|
||||
<li>Evaluate the existing revisions of the NDMP standard.</li>
|
||||
<li>Choose an appropriate revision (after checking of supported versions in
|
||||
commercial backup systems).</li>
|
||||
<li>Implement at least a NDMP data server.</li>
|
||||
<li>Bonus: implement a NDMP tape server (to allow attached tapes to be
|
||||
used).</li>
|
||||
</ul>
|
||||
<p><strong>Requirements</strong>:</p>
|
||||
<ul>
|
||||
<li>Access to a commercial backup system with NDMP support
|
||||
(mostly for interoperability testing; since a NDMPcopy
|
||||
application seems to be available, this is not a hard requirement).</li>
|
||||
<li>Good knowledge of a programming language which is included in
|
||||
the base system.</li>
|
||||
<li>Knowledge about UFS snapshots.</li>
