Then use consistency groups. You don't need them for DB2 though - with FRBACKUP, and since DB2 is 99% of my data, I'm good. I backup 20TB of production data every night to tape, no big deal. The point is there are plenty of tools available - multi-volume datasets are no big deal, you have similar problems even if the datasets aren't multi-volume.

True, the window for corruption may be somewhat smaller, it still exists.

Many use full volume dump/restore as a foundation. Unless -all- of the volumes are dumped at a single point of consistency (POC), then you'll have corrupted datasets. With the size of today's DASD farms, getting a window wide enough to get that POC is quite the challenge.
