I believe you can use flash copy (or similar). I looked at it a couple of releases ago (we're now z/OS 2.1) and at the time you could not restore a backup using FC to a new name. Seeing that the typical request is to restore individual files in the file system and not the whole file system, this was not a workable solution for us at the time. It's on my list to re-visit.
At the moment we use a home-grown, PAX bases, rexx, that probably won't work well for the size you're looking at. Our DR relies on disk mirroring, which includes the zFS volumes.

When DFHSM does a backup it will use DFDSS to do the work. This quiesces the zFS until the backup completes. This can cause the zFS to be unavailable for a long time (30 mins or more) while the quiesce is waiting to complete or the backup is in progress. If DFHSM cannot quiesce the zFS then there is no backup Do most shops let DFHSM do backups on zFS files? Do you have a limit of what size zFS DFHSM is allowed to do the backup? Do you have a window when you allow DFHSM to do such backups? How do you create a copy of a large zFS for Business Continuity or DR?
