Directory Storage Pool - Backup Performance
When backing up my storage pool containing directories-only (disk) to copy pool tape, it takes about 1.5+ hours to get through it. Obviously it's not very much actual data but does alot of tape mounts/dismounts due to the copy pool being collocated by group.
The primary diskpool (filesystem, not raw) consists of 4 x 5GB files and is 43% utilized. Anything I can do to get a little better performance?

How many groups do you have? Is this from one big storage pool?
If you have just one big storage pool and this many collocation, there isn't much you can do. Even if the primary is on random storage pool, you are limited by the backup stream (max process) and number of tape drives available.

Thanks, I figured as much but thought I'd see if I was missing anything.
This is dir stg pool is Windows directories only. I have about 20 colloc groups, BUT not all nodes are in groups so there is ALOT more going on than what just 20 colloc groups would be doing.
