I fully understood your personal goals. However, the other side of the
question, "anyone" in the title, did not include this alternative view
that I felt deserved mentioning. That's all.

Hello Harold,
As the originator of this thread, my goal was two fold. First, to
provide a file level backup (and possibly restore) solution. Second,
it was to get back into VM again. I stopped using VM, unfortunately
in 1992 or so (other than as a G user).
It is why I wrote the subject as "Would anyone like ..." I thought
maybe there was already an existing VM/CE solution. From what I'm
reading there isn't a VM/CE file level backup solution. I even
remember reading one person saying he'd like to use it on a live
VM/ESA real iron system.
I look forward to bringing it back to life for my own resurrection in
the VM world. At the time people liked the approach to ask me to
present at Share and IBM wanted to buy the rights from OCF to it.
I hope this reply answers some of your questions. As for using
Windows to backup our system, sure but its like doing a DDR backup
and restore. You lose all of the system changes since the last DDR
or Windows backup. It also wouldn't help the VM/ESA guy or help me
come back to VM.

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.

+Hi,
I'm wondering if a VM Backup program would be useful for people
using
VM/CE. I can see both reasons being yes and no. Thus my
question
about a VM Backup program for VM/CE?
Thanks.
