Our linux software RAID.

However be aware that mirroring is not a viable method for backup, as at the same moment the first drive is changed the mirror drive is changed as well, so the backup copy is the same as the original.

Better to mount a separate drive, back up server to it, and unmount it.

Better still to backup to a drive on a separate server.
