Hi - stupid query for future development.

I realize I could probably nice these jobs, even from cron, would
it be worth having a switch that, I don't know, changed the number
of dump threads based on time-of-day ?

Something like "After 5am only allow 2 active rather than 4 active dumpers ?"

Is there anyother, better, smarter way to reduce amanda load on
the system automatically ? I'm not certain that nice will allow
the tasks to complete, where as having few tasks at the default
cpu priority might.

I seem to recall you are on solaris.

What kind of system is this and what else have you got running on it?
