Keep in mind: rsync != RAID1 Using rsync, you'd have a periodic cron job that would mirror one drive to the other. With true RAID1, however, as Eric was explaining, the kernel mirrors driveA to driveB in realtime. Getting rsync set up would be quite easy. Just install the new hard drive in the box, create a partition on it and create the fs. Once this is complete, mount the drive somewhere, then run a command like: $ rsync -av --progress --delete / /path/to/mount/point This would mirror the entire contents of / to the second drive. You'll want to do add a few "--exclude" rules to that command, though, to exclude /proc, /dev, etc. -erik
