We r using NBU 6.0 to backup MS exchange 2003. It has 4 storage group SG1,SG2,SG3,SG4.Current setting is it has 1 tape drive dedicated to it along with multiplexing.I want all storage groups to go to different tape drives[we have drives available].plz help
First - is to disable multiplexing (they will go to the single tape multiplexed otherwise)
Second - insert NEW_STREAM directive BEFORE specifying of SG in the Selection List.
Third - make sure that your backup policy allows multiple streams
Not sure if this is the most efficient way to go about doing things, but you can set up four different storage units, one for each tape drive, and then create a policy for each storage group and point each policy to a different storage unit.
After reading Mouse's suggestion, I guess I was off base as to where you were coming from. His is definately the way to go, but if you want to control which backup goes to which drive, you could do what I suggested.
