Hi
I am trying to find out if there is a utility in z/Linux in my case RHEL
5.2 that will allow me to copy a z/Linux formatted disk to another disk.
Also do you know if DDR cares rather there is a VTOC on a volume if it
is used to backup the volume without a VTOC?
Thank You,
I use dd
dd if=/dev/... of=/dev/...

DDR won't care. It will take the VTOC with it.

DDR doesn't care about VTOCs or anything. It simply copies whatever is
there. A very useful trait in many cases.

Hi
Further explanation. Here is my dilemma in a nut shell:
I have a z/Linux volume on a guest that does not have a z/OS VTOC. We typically
use DFDSS on z/OS to back the z/Linux disks up and restore them at out DR site.
Since this particular guest does not have z VTOC DFDSS cannot open
What about Bacula? Dr Boyes could speak could speak on this point better
And you always want to shutdown the guest to get a good backup

If you have flashcopy on your dasd that may be your best option. Use the
vmcp z/Linux module to invoke the FLASHCOPY command.

Flashcopy does not account for any disk buffers linux still has cached and
unwritten. It will mitigate the situation where the disk is changing while
it is being backed up.
All in all, if you're talking about running images, full-pack backups are
basically worthless.

Wouldn't doing a dd in the running Linux guest to a separate disk, then
backing up that disk result in a good backup? Assuming that the application has
synced its data, of course.

Long term, setting up Bacula would probably be a Good Thing, but probably

If you unmount the filesystem you dumped
There's a race condition that the dd can't account for. Think of a
transaction in a database, where several records are part of a transaction.
Each record gets written in turn, and then the transaction is committed.
What happens when the dd goes through that section of disk when only two of

Hi Terry -
As a couple other folks have mentioned, dd will work to do that, even if you
dump the image out to a tape or a disk file. However, you will need to make
sure that no changes are taking place on the disk you are dumping while you are
dumping it, which leads back to the same issue as

Hi David,
Thanks I agree and I have already started working on getting those packs
fixed up.
Thank You,
