        Subject:        restore/retrieve optimalisation


Hi all,

last week I received a question from a retired professor who was digging
into back-up solutions. One of his major concers was the amount of
tape-mounts required in a large restore or retrieve operation. I told him
that TSM optimises for a minimum amount of tape mount based on the list of
files to be restored or retrieved (with the possible state of collocation
as
a given fact at that point). He then asked me to provide documents stating
exactly that.. Now we all know it's true, and Andy has been heard making
this exact statement last week in Oxford, but where is this written down?
I've been reading through several TSM documents, including the TSM
concepts
redbook, but I've not come across any document that explained exactly
this.

Could anyone point out a document to me that I could give to this
professor?
