If I had to do it over again, I'd probably do one policy per server.
This makes it *much* easier to disable a client while it's being worked
on, rebuilt, or whatever.

The incremental and the full have to be in the policy.

NetBackup does the smartest thing within a policy and it depends on if
you're using frequency-based scheduling or calendar-based scheduling.
If you use frequency-based and a weekly and a monthly happen to fall on
the same day, the monthly will run today and the weekly will run the
next time a window opens.  With calendar-based scheduling, you can tell
it to ignore certain days for say your weekly and do the monthly backup
instead.  We don't like calendar-based scheduling very much since it's
much, much harder to deal with failures.
