Running dedup automated or on a scheduled

What is the best practice running depulication on NFS VMware volumes, on a scheduled or just automated?

I guess if you run it automated it will start when there is a certain amount of new data written to the volume, this can happen during peak hours and again impact performance?

While running scheduled you can be sure the dedup jobs are running during off peak hours?

Dedupe can be quite CPU & disk-read intensive, so most people run it on schedule during 'quiet time', e.g. over weekend.

Okey thank you for the respons

But what about the schedule, I see you can specify the weekday and the hour, but will it run until its finished, or just the specified hour?

it will run until it finishes, but you can always stop it manually.

If you don't have "off hours" then using automatic scheduling has the advantage of only using resources to de-dup when it reaches your threshold.  Our environment is 24/7 and there is no such thing as off-hours, so we use auto@10 and 20 to guarantee it only runs when needed.
