Or, to put it another way: RAID is NOT a substitute for regular backups.

There are other reasons besides uptime to use RAID, I often use RAID0 to 
improve disk system performance. It does increase the odds of failure, but 
you shouldn't be depending on RAID to protect your data, that's what backups 
are for.

I just wish tape systems with the capacity to back up modern hard drives were 
more reasonably priced. For the cost of a blank DLT tape I can buy a 500GB 
drive.

I'd like to see a tape system that could hold 1TB per tape, at a reasonable 
price.
