August,
I do agree that static data would be usable but, the response was limited to
the question, no mention of z/VSE utilities.
'Can I backup/restore both z/VM and z/VSE using DDR ? Can z/OS
backup/restore z/VM ?'
Active VSAM/DB2 data could be corrupt after the restore with either DDR or
DFDSS.
Regards,
Doug

I would beg to differ w/ this
you can recover any component of a backed up running VSE system
how many system crashes are planned ? w/ op system down ?
what good is a DR plan if you can only restore from a planned outage ?
VSE utilities should also be used as fallback , such as power off-loads,
fcopy etc.

Daniel,
You can get a valid/usable backup the z/VSE guest dasd with DDR -ONLY IF-
the z/VSE guest is shutdown while performing the backup.
You can use z/OS DFDSS to backup the z/VM and z/VSE dasd but (IMHO) it is
not a wise solution because of the restore considerations. With enough
practice you could make it work. Problem is the z/VSE guest would never
work
correctly unless it were shutdown during the backup.
You can backup the running z/VM system with DDR (minus the page and spool
volumes - format the page and spool volumes, cold start the spool after
recovery). You would have to re-save CMS and other DCSS or use SPXTAPE to
save the information in the spool.
Since you have a z/VM system, this would be a good time to try using z/VM
under z/VM to validate your recovery process. If you forgot something just
scrape the 2nd level system and start over. (kind of like using Changeman
to
maintain Changeman).
Would be glad to discuss with you offline.
Best Regards,
Doug Shupe

Subject: Backup of z/VM and z/VSE
I have been given an assignment to backup our z/VM and z/VSE systems.
We also run z/OS. I know about DDR. Can I backup/restore both z/VM and =
z/VSE using DDR ? Can z/OS backup/restore z/VM ?
