(with the RAID 1's backed up to the RAID 4/5's before those are backed-up to tape.) Tapes are taken off-site daily. (with backup/restore procedures tested monthly. etc.. ) We're in a data centre that isn't likely to have blackouts. (It can run on batteries for 6 hours, and has diesel generators with 48-hours worth of fuel on-site, as well as an emergency supply-chain for the diesel.) I've not seen problems as described below on 3Ware cards... I believe the configuration for each RAID is is backed-up on each disk in the RAID set. I've never had a problem with those. (I have seen a problem with another brand of SATA RAID controller, when in RAID 1 mode, putting a blank replacement in a bank after a drive failed caused the controller to rebuild the BLANK drive onto the GOOD drive.. erasing all the data.. thank goodness for data recovery.. we had to get the data back of the drive that had gone bad, and managed to retrieve it all!) XFS filesystems no all of the above, just for reference. A.
