[GRLUG] To Raid, or not to Raid, that is the question.

[Don Wood]

> Isn't a backup a form of redundancy?

No,  a backup is a recovery point.  A backup represents a point in time [and
thus, inherently, in the past - not current, which is what RAID provides].
With RAID you have redundancy which provides availability [against a
specific single point of failure] but if you delete your data [or if the
application/OS/firmware/cables/etc... do a brain-swirl on your data]... your
data is gone.

Ya got me on that one.
