<ul></ul><p>DDS4 seems near the sweet spot regarding cost vs. specs.</p>
<p>Example unit is <a class="external" href="http://www.tapebackupandraid.com/tape_library/son-sdtd11000pb.asp">http://www.tapebackupandraid.com/tape_library/son-sdtd11000pb.asp</a><br />It is ~ $1000 media costing ~$20</p>
<p>Media is 20G uncompressed, I think we should get near 1:2 compression on what we<br />need to backup -- postgres sql dumps, user loaded files etc.</p>
<p>Speed is 4.8 MB/s assumming 2:1 compression.=> 30G of backup in 1.5 - 2hours ..<br />reasonable.</p>
<p>Plots can be up to 30kb in size (relevant data contained, not the mdb files that<br />are up to 3MB!) ... we expect 200K by next year and up to 1 million after that.<br /> => 200K plots =~ 6G<br />Plots may get bigger ( there is some interest in images being associated with<br />them) but I think this backup technology is sufficient.</p>
<p>Timing of this need:</p>
<p>Vegbank 1.0 with an implicit contract with users of safe storage is scheduled<br />for April 1st ...a foolish and ambitious date but driven by the need to tell NSF<br />we have completed grant 1.</p>
<p>-----<br />I have slight knowledge of backup tech but maybe some of the project specific<br />info will be of use. I've been know to mishandle ye olde decimal point so take care.</p> VegBank - Bug #560: purchase and set up tape backup for vegbankhttps://projects.ecoinformatics.org/ecoinfo/issues/560?journal_id=19162003-05-08T23:04:26ZMichael Leemlee@nceas.ucsb.edu

<ul></ul><p>After discussing with JH and Colby, I suggest that we DO NOT install a tape<br />drive on vegbank just yet. Instead, we can automate backups to the new RAID<br />Colby's putting together which will have 2 TB of space.</p>
<p>We can always install a dedicated tape later.</p> VegBank - Bug #560: purchase and set up tape backup for vegbankhttps://projects.ecoinformatics.org/ecoinfo/issues/560?journal_id=19192013-03-27T21:14:39ZRedmine Admin
