What are the advantages of using an external hd with software like Norton Ghost as data backup over RAID? I believe RAID only protects against hd failures and not viruses, power surges, or whatever else. Does backup software copy everything onto an external hd so if the internal drive fails for whatever reason the external drive can take its place and all the data, o/s, and programs be transferred over to a new hd? If backup software used with an external drive is very reliable, would copying files onto a thumbstick as further backup be necessary? Thanks for any replies.
