Sam, I strongly concur with everything you said below about ICFRU, IDCAMS (and not just EXPORT commands) and DFSMShsm. As a former CR+ user at my last job, it, like T-REX, runs rings around IDCAMS, etc. to the tune of being *** TEN TIMES *** faster at a lot of things.
And while I like DFSMShsm, "leery" doesn't even begin to describe my feelings about using it as the primary backup and recovery tool. :-) Bob --------------------------------------------------------- Robert B.

CATALOG backup and recovery gets special attention here as well with backups during our normal nightly point in time copy window as well as special backups the next day before prime daytime processing. We use T-REX from Dino Software http://www.dino-software.com/ There are other good products but I don't think in a large ICF catalog environment just IDCAMS, ICFRU, and DFHSM are good enough. I am a little leery of letting DFHSM backup catalogs using EXPORT automatically. We have seen performance issues in the past with EXPORT running on large catalogs. That is one of the reasons we use T-REX for backups it is a lot faster. You can have too many backups if the DFHSM backup slows us down during busy processing.

In my opinion, what *does* matter are your DR considerations, *and more importantly*, what catalog backup and recovery tool your shop is using. As Ron Ferguson always taught, "Catalogs do break!" And he should know.
