Well, at least you have to give some more information: How much data=20
does a full backup consist of today, how many generations of backups do=20
you need, how many do you want, do you want to store volumes off-site,=20
can volume management be done daily, weekly, or never at all... and,=20
very important, how much of your data changes daily, and how fast does=20
the total data volume grow?

Depending on the machine and, quite important, if the catalog database=20
is on that machine, too... usually not a problem.

Before we can suggest or even discuss changes we'll probably need a=20
little more information about your setup.

For example: I use a very old server with a DLT autoloader, I have tapes =

holding about 1.5 TB, I back up 6 machines, I keep backups for a year,=20
and I run the catalog database on a separate server. I can run up to=20
five or six jobs simultaneously. Not very interesting - you'd need to=20
know much more about my backup schedules and the amount of data I=20
collect from the different machines.
