WARNING: To do this reliably, you need software that is capable of establishing an I/O consistency group. If you want to FLASHCOPY the volumes and sequentially backup the volume copies, that's ok, but do NOT just sequentially copy the live volumes of a running z/VM system. (If you wouldn't do it to a running z/OS system, don't do it to any other system.) This process is intimately tied to your DR strategy, too, so get it right. If you have databases, use the backup software for the database. If you're using hardware replication, be sure that it's supported by the database vendor. Some people take a too-casual approach to backups and DR. I too often hear "Don't worry, I'm doing it from z/OS." as though z/OS has magical powers over z/VM and Linux. Don't fall into that trap. That way there be dragons.
