I have watched this thread and continue to come away with "what is the
objective of this discussion?" Is it about backing up your VM DASD or
is it about resurrecting some past capability? I realize it could be
both.

But, no one has mentioned that in the Hercules world, backing up ones
DASD can be done quite easily. Place all of your DASD host files in
the same directory. Shut down VM. Compress and zip up all of the DASD
images into an archive file.

Recovery is the reverse, but attach your unzipped DASD volume(s) from
which you want to recover files or minidisks to those already gened
extra drives in VM and move what needs moving. The Hercules
configuration file makes this connection.

Be careful to preserve shadow files if you are using them.

This may not work as desired so feel free to shoot it down. Just an
approach I have not seen discussed.

Recovery is ad hoc in most cases. So some augmentation with some VM
data when the backup is made might help. But this boils down to level
of effort. Let the host do the heavy lifting where it can.

Some folks like to stay within the "VM walls". That is perfectly OK,
but we are living in a different world with Hercules and can approach
problems with Hercules and its host being part of the solution.
