Maria - I accumulate such tips in my ADSM functional directory,
at http://people.bu.edu/rbs.
You say that you have "collocation turned on" - but what kind?
Collocation by node is insufficient for your purposes.
>From my tips:
Parallelize backups Going to a disk pool first is one way;
then the data migrates to tape.
To go directly to tape: You may need to
define your STGpool with
COLlocation=FILespace to achieve such
results; else *SM will try to fill one
tape at a time, making all other
processes wait for access to the tape.
