I am a VM sysprog, I don't need to remember all of OS extend acronyms. :)

Two of our production Linux instances are VERY UN-busy at the time of our
backups, and the third is brought down for the duration of the backup job.
It is submitted from VM and returned to VM for post-processing. If the job
does not come back in a specified amount of time, the Linux instance is
restarted regardless. All VM and Linux volumes are linked READ-ONLY to the
OS/390 guest so he cannot do anything naughty.

When we do come up at the hotsite, the linuxes do mention that their
filesystems were not unmounted cleanly (for the ones that were still logged
on) but the normal cleanup at IPL time has never failed. If they were to
fail, I have a skeleton / filesystem that I can put in place and use TSM to
restore from the OS/390 server. This is a long process but it does work at
the DR site.
