DFdss, REPRO, EXPORT, HBACKDS

And google only gives 1.3 millions hits on the subject.

You would not normally back up a user catalog into a user catalog -- you would back up into a sequential file on disk or tape.

Perhaps if you explain just what it is you are REALLY trying to do, we can help you. When you tell us one thing but do something else, our advice is not likely to work.

As mentioned already, you would usually run a backup with EXPORT to a tape file instead of copying to another KSDS.

Because all of the alias pointers in the master catalog would be pointing to the original user catalog and the volume on which the original resides.

Using EXPORT / IMPORT, HRECOVER, or DFdss RESTORE, the recovery procedure is simplified by recovering the broken catalog direct.

The questions as originally posted was about BACKUP of a user catalog. From the AMS for Catallogs manual (emphasis added by me):

I must admit, following the recommendations of IBM does make for an easier life (Mostly

)

It is often expedient to take more than 1 backup using different utilities in case one backup gets broken. An EXPORT and a DFDSS DUMP are the easiest, and for the equivalent recovery.

It is possible to REPRO to another catalog with NOMERGECAT specified but I strongly suggest you don't do that as it won't be much use to you unless it's for a Mastercatalog backup/clone where the datasets are nonSMS and cataloged to '******' which the system recognises as IPL volumes.

Manual z/OS V1R10.0 DFSMS Managing Catalogs states the following

Nevilh - that's true. A REPRO updates all the contained datasets VVDS back-pointers to the target catalog name and actually moves the entries to the target catalog if MERGECAT specified. Of course that then needs all the Alias pointers changed to the new target catalog as well.

praveensinha - I would never advocate using REPRO for a normal Usercatalog backup! Don't go there.

Must admit, I usually use EXPORT and / or DFdss.
