The only supported way I know to make a copy without recall is to use
an HSM ABARS backup. We have done this in a (very) few instances, and
depending on the reason for the backup it may suffice.
The main limitations of this technique are (1)someone with proper
authorities will have to define the appropriate ABARS entity with
definitions for the tape dataset name(s) to be used for the output and
the dataset that will supply the list of datasets to be backed up;
(2)The design of ABARS is geared to restoring all datasets in the
backup, not just one. There may be some tricks to partially get around
this, but if you need to be able to restore a single dataset without
affecting the others, this could be a problem.
The advantages of ABARS are (1)it will backup datasets that are migrated
by directly copying to the output dataset the migrated datasets (with
tape mounts, if on ML2); (2)it can restore datasets that were migrated
when backed up as migrated datasets without tying up primary DASD.
ABARS is designed with complete application system backup in mind to
support total application restore in a Disaster Recovery, where all
application datasets must be restored at the same time. We haven't
found it too useful for that (we would have to define almost the entire
shop as one humongous application), but have found it useful in a few
isolated cases where the reason for the backups is archival in nature
with very low likelihood the data will ever be restored.
If ABARS doesn't work for your application, you're stuck with the need
for recalls.

I want to process 30 big datasets which are migrated. I may recall
them, but I'm not allowed to HMIG them.
Is it possible to access them without recalling them?
Maybe it is possible to get a copy of them, without recalling them?
