We have a much smaller environment, 150 servers, 8TB data, including 2
exchange servers.  Mainly windows.  One IBM3583 library (6 LTO-1 drives,
60 slots, all SCSI), one tsm server.  Library is about half the size we
need (in slots and drives).  I am supposed to be half time on backup,
half time on a dedicated application.

Between me and one other person, we put in at least 8 hours per day on
backups alone.  Some weeks I average 12 hours per day fo 6 days per
week.  We are budgeted for 4 hours per day, 5 days per week.

I hope this helps.

I don't know of a exact number, but maybe this will help. 

We recently engaged IBM and other hardware vendors to look at upgrading
our environment.  We or should I say I, manage 120tb of TSM data in
total storage with a database size of 70 gb.  Recommendation was 1.5
admins. One server and one library.

We are in the midst of our Annual Budget planning and know were are
understaffed.  The question then is there a "Ratio" of Backup Data
Maintained to number of Backup Administrators?  A few of us have googled
and Gartnered, and come up with nothing.  Has anyone on this list seen
such a thing?

Thanks in advance!
