I guess I was recommending that it A. happen in the future, or B. they
design future hardware with the ability to programmatically redirect
the stream in hardware to a new device on the fly. I.e. the OS still
sees the same disk as mounted and writeable [sort of an on-the-fly
bastardization of RAID 1] but the controller knows what it's doing and
the special software would hook into that for backup/restore/repair.
