Have you look in a DataDomain Forum, they can probably offer you more options.

You must be careful when planning your cleaning jobs.  They are very resource intensive on the DD devices, and they can take a good chunk of time to run (5-10 hours)

Be careful when capacity planning also.  If you find yourself in need of space on the DD, you can not just expire images in NBU and expect to see that space freed up.  You must expire the images, then run a cleaning job on the DD.

As for the syntax, from the CLI of the DD you can run the clean command -help, or -? (I cant remember which)  but it is very clear from the help documentation as to what you need to run.

I switched companies and dont have access to DD's anymore, so I couldnt quickly print the help menu.

The throttling of the clean jobs is also important if you want backups to run through a cleaning.  I believe we had our throttle set at about 60%, and in times of dire need to get storage, 75%.
