No, that's fine - really! I appreciate you taking the time to consider it and responding.
I'm still trying to figure it out. I have a DS6800 with a some FC drives and a lot more FATA drives. The FC ones are faster. So I was wondering whether it might speed up HSM's backup window if I put his daily backup volumes on the FC disk. However I can't afford to put loads of them on there, so I was wondering if it might be better to have just a few, even one, volume in each daily set and a lot of spill volumes. Maybe the spill process itself would negate any benefit in the backup window speed. However I think the space utilisation *may* be better on spill volumes, since they are a repository for the whole backup pool rather than just a single day. And I have no logical reason to keep my backup images in pools separated by day. Difficult one, I think..

Sorry I can't provide better information on this, and I think I should know this one, but I can't find anything that says it's a bad thing to do, it just feels bad to me. Not much help I guess.
