PPDM Backup Occupancy per Asset

Hi All,

We would like to know how much backup storage each asset uses. Is this possible?
Ideally before and after dedup/compression.

Looking at the REST API, I can only find the numbers in the /activities function (BytesTransferred and postCompBytes). Unfortunately after around 6 weeks the activity info is deleted. So this is not an option (for long term backups).

REST API functions /copy-map or /copies are interesting, but don't seem to contain the information we are looking for.

Any help is appreciated. 

Kind Regards
Tom
