TSMs' use of disk is still probably the best on the market, versions can
be migrated from dosk to tape, 
 
Siobhan> You can do that in NetWorker - It's called Staging
 
there is also the ability to merge multiple tapes together eg when 2 tapes have 
only 40% useful files merge these onto
another blank tape. 
 
Siobhan> You can do that with NetWorker.
 
Thirdly I recall there was the ability to consolidate
one or meor servers onto one or more tapes ( to reduce the number of tapes
required for a full recover.

Don't recall a limit, but do recall that you can simulate the full inc
cycle instead of inc for ever.

Siobhan> Actually, if you look at the latest info from IBM, TSM is moving 
towards the full/inc idea.
