I'm with Wanda on this.  The others at Central Site know enough to cover
for me when I'm out, and my primary concern is with the adsm server (one
in, another on the way, 900 clients).  Where I differ is on the setup of
client support.  Since desktop support is a function of the various
devisions, both administrative and academic, I have a domain per division
so the local administrators have control over their own backups and
registration and scheduling is a local affair.  If they have problems, they
call me.  We are talking about a policy that if you install the code, you
use it;  machines that haven't had a backup in a certain number of days get
deleted.

Lisa,

We have 3 independent ADSM AIX servers (3 physically separate networks).
We move about 75 GB per day; have 6 TB stored on tape; 600+ clients.

We have 1.25 ADSM administrators, plus another person trained to back us up
in case we both get hit by a bus.

Plus, the desktop support group that  supports all other desktop
applications (windows, mail, Word, Excel, etc.) are first level support for
desktop users with ADSM client questions and/or hard drive failures.  They
also have domain authority to register desktop clients, set passwords, etc.
I am "level 2" support for them if they run into a problem they can't
handle.

Administrators of AIX and NT servers are responsible for installing and
supporting the ADSM client code on the machines they own.  I generally train
them 1-on-1, which isn't too much trouble since they end up supporting
multiple machines.  I am then "level 2" support for them if they run into a
problem they can't handle.

If we had not "outsourced" the client-end support in this way, we would need
a LOT more ADSM admins to manage 600+ clients.
