Karl--About the biggest problem you are likely to face if you take
backups of 530RES and SPL is that you might or I should say, would, lose
open VM spool files. An ipl from the restored volumes would have to be
done using "FORCE" rather than "WARM" because there would have been no
WARM START DATA saved. For better or worse, our normal backups are
taken against up and running VM systems.
Since you're running z/OS and doing backups from there, I would
recommend doing regularly scheduled backups. The wasted effort or
redundant or duplicate backups are a small price to pay for the security
of knowing that a change was made and you or someone forgot to take a
backup. Tapes sometimes go bad. If you have a previous backup to go
back to, that's another safety net.

We just installed z/VM 5.3. We have 2 systems running. VM1 and VM2.
Right now, all of our Linux guests (about 5) are on VM1. They also have
a directory entry on VM2 (but password set to NOLOG).
1) What's the best way to do failover if we need to get something over?
Right now, my plan is basically to log into VM2 and change the NOLOG to a
password and then start the guest. Basically I want to avoid having
our Operations staff make mistakes and start 2 instances of the same linux
guest (on 2 VM systems).
2) We use FDR/ABR on our z/OS side for backing up for Disaster Recovery.
We would like to keep using FDR. Now I know I can get clean backups if
the systems are shut down. Are there any gotcha's if I take a FDR full
dump against say 530RES or 530SPL while the system is up? \
3) last of all, how often does VM get backed up when it's just used as a
Linux server system??
Thanks
