dd is only good provided the fs is umounted, or at least mounted
read-only.

Anyway, if the power fails, BOTH your RAID partitions will be
in the same incoherent state, needing fsck, and in the bad cases,
manual intervention.

Your idea of ``from time to time copies'' is good. If you unmount
the backup after the copy, the only ``dangerous'' window is
during the copy.

By the way, how do you intend to automate the recovery process ?
One idea would be to have a partition which is never written to
(initrd) and which attempts to mount all the other partitions,
doing fsck when needed and if fsck fails, mount the alternate.
