Deduplication schedule options

[joostvandrenth]

I was just wondering about deduplication schedules. Now that we have more and more systems running dedupe these days scheduling the runs can be a bit tricky, notably when we deal with older systems with maybe not much IOPS and CPU to spare. My question is whether there is a possibility to either schedule dedupe runs per month or to set it to run automatically but have it honor a runtime of 20:00 -> 06:00 when it runs. The default schedule option per week is not enough when dealing with many volumes in my opinion.

can operation manager help out in some way?

Basically saying to run dedupe every night, which in practice should shorten the runtime enough to prevent resource contention.
