What I've never been able to figure out is how to tell z/VM that the backup
process on z/OS is done and to either change runlevels or IPL the guest or
what have you.
Again daily system shutdowns are not suitable for a 24/7 production
environment. So how to balance the need vs the reality is the real trick.

Except that then you're backing up dirty Linux FS volumes.
If you're going to take volume snapshots of Linux guests you need to
shut them down cleanly first.
