Hi Werner,
I'm sorry about a minor error on my side. I said (believed) that move
nodedata had parameters to move only active files, but the possibilities for
reducing the data to be moved are limited to
type=ANY|Backup|ARchive|SPacemanaged. In your case Werner, that doesn't help
alot. My mistake.
I don't have much experience with backupsets, but I think Richards idea
about MIGDelay seems very good.

As to the versionquestions in my first mail - MOVE NODEDATA is only
available in v. 5.

Rgds.

Hi Richard
thanks for your hints.
We still hope on a solution that makes us happy. The idea with BackupSet is
theoretically the closest one. But I heard from people with experince, that
(i) its not so easy to restore a client with the newest backupversions and
(ii) we have the time-problem moved to the process GENERATE BACKUPSET
(collect/consolidate all newest versions).
Regards,
werner

Werner - As Geirr said, Backupsets are the optimal solution but, as all
         solutions, will require extra processing time.
Another approach is to exploit the often-unexploited MIGDelay value, on
the primary tape storage pool.  Try to match that value to your dominant
Copy Group retention value, and migrate older files to a next, tape
storage pool, and let reclamation naturally bring bring newer files
closer together.  This should get inactive versions out of the way.
The cost is extra tape data movement.

There is no "ideal" solution.  Opportune full backups (weekend?) will
get you closest to what you want.
