It appears from this thread that the question and most of the responses
referred to backing up Linux volumes, but I discovered something last
spring or so when we were polishing up our D/R backups. We use DFDSS on
z/OS to do full volume D/R dumps for both our MVS as well as our VM
dumps. My initial thought was that we could use S/A ADRDSSU to restore
a single volume VM system and then get a bunch of restores running at
the same time. You can't do that, at least easily. S/A ADRDSSU does
not restore, at least correctly, the allocation bit map (rec 4 or 5??)
on a CP owned volume that maps out space. I guess you could use S/A
ADRDSSU for the restore and then S/A ICKDSF to allocate, but if your
record keeping is out of sync with what's on your tape, you're out of
luck. This is documented in the ADRDSSU manual, at least as far as not
being able to correctly restore the allocation record for a VM volume.
This is only the case for the S/A version of the program.
We ended up documenting the S/A restore of a starter MVS system and then
we'll use it to restore everything else. Wish we had FDR.
