That depends on your goals in this backup.  If fast recovery from a
drive loss is your only criterion, RAID would be better, but swapping
it into a completely different machine might be harder.  And neither
one protects you from losing the whole machine, of course.

Nothing you can check "live" will be nearly as certain as trying it.
