Migrate Inactive Files Feature Proposal

[Orville Lantto]

I had an idea over the weekend and would like some comment on its feasibility.  
With the growing need for disk-to-disk-to-tape backup strategies, it would be 
very nice to be able to migrate ONLY inactive copies of files out of a storage 
pool.  I can come up with no reason that this should be difficult or impossible 
to be added as a TSM feature.
 
Any comments?
