ClearCase continues to suck

So a couple of RAID controllers go out on a couple of the ClearCase servers yesterday, early in the day. About a day later, we finally get the message that servers are back online after having had the controllers replaced and the drives re-checked. I get in around 13:00 from a dental appointment, check my system, and find that the main tree in which my team is doing its work is behaving irrationally. I report the behavior to our support staff immediately, and an hour and a half later get a note that it’s being restored from backup and will be available in four hours, by which time the work day is over. That’s two days of work lost, when we could’ve restored a CVS repository from backup onto a spare machine in what, an hour? And been able to work from our checked-out files the whole time?
