Some OCF staffers are making a trip to Fremont to pick up some 500 GB drives so we have more space to backup user data. They should be back in Berkeley by 5 PM today, and I'll be working through the night to setup the drives so that we can dump data to them.
Home directories have been successfully backed up, and we're currently going through web space. After web space, we'll have Microsoft Windows profiles and MySQL/Postgresql databases left to backup (I'm sure the other staffers will correct me if I'm missing something here).
Oh, and in regards to a user's comment, yes, mail in other directories should be restored (they're part of the home directories, which are almost done being dumped from the array).
Thanks for all your support!
