Wikimedia is starting to use external partners to allow for better disaster recovery and quicker response time in case of a data center wide failure. The first large scale case use is being proxied thorough a company named eBart.

• User access: tomasz
• Type of access: ssh
• Space: 6.9T

The plan for this is to have a snapshot of Commons available offsite if anything should happen to our data center. The total allotted space should reach upwards of 10T's in the next months as more drives are added to the system. Ideally this off site will host both a snapshot of Commons and possibly an archive of the XML snapshots.

Notes on coverage:

• Between 10 and 17 CET/CEST (between 08-09 and 15-16 UTC) ability to reset the machine quickly.
• Between 07 and 01 CET/CEST (between 05-06 and 23-00 UTC) ability to contact other staff with a 20 minute window to reboot.

Status

I'm currently pushing our archives of 2008 XML snapshots as the first set of speed tests. After those are in place we'll come up how to organize this in a more automated fashion. --Tomasz Finc 18:24, 8 July 2009 (UTC)

Were seeing fairly consistent speed when doing these transfers. A solid and steady 1.6MB/sec (16Mb/sec) going from amane to wm. --Tomasz Finc 20:25, 13 July 2009 (UTC)

Moving forward I'm going to push some more archives from Brion's archived drive. Since the Wikimedia Office has a fairly slow uplink, I'll be using my own link at home which can sustain an upload of 250kB/s (2Mb/sec). --Tomasz Finc 20:25, 13 July 2009 (UTC)

I'll do an archive of status successful and transfer those first. Any others will be judged by hand to see if they are worth archiving. --Tomasz Finc 20:25, 13 July 2009 (UTC)

Still moving these archives over. Just moved past frwiki on brions old drive while I'm at svwiki from our 2008 archives --Tomasz Finc 22:20, 27 July 2009 (UTC)

All the 2008 archives are now moved over. The older archives from brions drive are stalled as the external drive is throwing i/o errors. --Tomasz Finc 18:10, 30 July 2009 (UTC)
