RAID-1, a.k.a. mirroring.  THIS IS NOT A BACKUP, it's a way to keep running in 
the event of hardware failure of the primary drive.

However, if one drive gets corrupted, the other will mirror the corruption.  If 
the failure is in the disk controller, both mirrors can be useless.

If you want a BACKUP, back up to a separate box, preferrably with versioning so 
you have multiple copies of each backed-up file.
