RAID provides fault tolerance; you get realtime protection against hardware failure. Removable backups provide something different: the ability to easily roll back unwanted changes and recover lost data.Why removable? Why not RAID or something? Jack
RAID will protect you if a drive fails, but it will do little to help you cope with (for example) your server being compromised. If you're serious about data protection, you might want to consider both, but RAID is not a replacement for a reliable backup system.
With DVD burners coming down in price this might be a good option.. depending on the size of the data you need backed up. For anything over a few gigabytes you probably want either a replica server or a good tape drive..
