Thanks, likewise our linux guests and VM itself is down. I was more curious around the cp allocations for page, spool tdisk were they preserved.

But when we back up Linux and/or VM they are down so the backups are stable. Mace -----Original Message----- From: The IBM z/VM Operating System [mailto:[EMAIL PROTECTED] On Behalf Of Mike Walter Sent: Tuesday, February 19, 2008 1:30 PM To: IBMVM@LISTSERV.UARK.EDU Subject: Re: Backing up and restoring zVM 5.2 using IBM's DSS backup utility under zOS 1.7/1.9 Brian, Do you understand that if you backup any system from any other system, using tools which are not aware of file updates in cache, and files or databases which are spread across physically disparate DASD, then the backup is unreliable unless the system being backed up has been gracefully shutdown before the back begins, and is not brought up until the backup is complete? I.e. if you are backing up z/VM from z/OS, z/OS just backs up tracks of data. If those tracks are changing, the odds of reliably restoring the system are not too reliable (pun intended). That's not z/VM's fault. If you backup z/OS DASD from z/VM while z/OS it is running, the restore will probably not be reliable. If you back up a Linux guest running on z/VM from z/OS, z/OS is unaware of files cached on the Linux guest. Solution: backup a system using its own products which are aware of these limitations, or use backup tools at rely on a client running on the system being backed up to get a stable, reliable, and _restorable_ backup.
