If that was to happen with me on the mainframe Wow, and all of this time I thought z/VM ran on the mainframe.

Bravo, It is amazing that Opies here think that if you can back it up you can restore. I don't know how many times they have not been able to restore files and their solution is to change backup software. If that was to happen with me on the mainframe side I would be unemployed. I agree with Adam you should test a restore of a sample size of files from your backups in my opinion at least quarterly and whenever the backup parameters change.

And RESTORED, whether you need to or not, on some schedule. A good test, I'd say, is to pick ten files at random from the backup catalogue every so often and restore them to a temporary location, and then verify those files. (Assuming you can spare your tape library long enough, because ten random files is a lot of loading/unloading/ seeking.) Seriously: your backup regimen is USELESS if you cannot restore the files you backed up, and "when you need them" is NOT the time to find out that the tapes haven't been being written correctly.
