[QUOTE="XJ-linux, post: 1143590, member: 33722"] Mirrored RAID is safest. Speed shouldn't be an issue with Velociraptors. Time machine really just makes sure you have a very recent backup on hand, and keeps incremental backups organized as well. It doesn't protect from hardware (disk drive) failure. You might be able to set up time machine to actually use the RAID of 2 x 2TB drives, but I'm not sure if TM will allow one to backup to internal drives. Someone can chime in on that one I'm sure. Maybe you just can't back up to the boot drive? Anyhow, if TM didn't like the internal RAID, you could try Carbon Copy Cloner or Superduper. Both are pretty easy to set up incremental backups and a wide variety of other things that TM doesn't really do. Still, my personal choice would be a RAID any day of the week. [/QUOTE]
