I agree with John, this sounds very ambitious.
If you are only interested in active files, there is the possibility of
checking it on the actual client, how much data in each filespace
(filesystem/drive/etc).
A worst case (it gives all backup-data, active and inactive) could be "q occ
t=b"

Graham,
Your plan is extremely ambitious.
Is this a one off or are are you planning to do this regularly.
How are you goung to achieve this.
Anyway you can get a reasonable idea from taking the filepace occupancy,
unless
you have major excludes from backup, this is going to be your active file
size.
John

Subject:  Estimating size of backup sets



TSMers,

Is there anyway people know of to estimate how large a backupset is going
to be? I have close to 700 nodes I want to generate backupsets for and I
want to know
what sort of space I will be using up with them. I am assuming it will be
some sort of SQL statement looking at active files, but I can't figure it
out past that.

Any help would be appreciated.

Regards,
