We also use VMBackup as our backup >software. I thought I was reading about SJU. We're similar except we run *-TCP. What's the problem? In our case, if I try to get a FILE back from VMBackup I get told that the disk isn't a cms mini-disk, which is news to me. So far I've been able to get what I need by keeping an extra (big!) mini-disk around and telling VMBackup to recover the entire disk with the file I need to the spare disk. Ugly, but it works. Operations says that VMBackup does spend a lot of time when it hits those notebook disks (500, 1000 and 1500 cylinders) so your estimates sound plausible. Our users don't like us to go offline for hours, and if we do then the system is bogged down for hours more until we catch up. So, yeah, I'd say we have a sub-optimal situation, but we've gotten by. So far. -Kary
