Dear proxmox team,
I've recently deployed a proxmox node together with a proxmox backup server. Since the backup server is shared with another administrator, I decided to encrypt my backups to keep them from being tampered with, if one of us is being compromised. Even though we have about 15x the storage on the backup server than used in deployment, the main datatore went out of space in mere months.

Now it is up to us to find the culprit hosts, which are not deduplicated or pushing too much storage content.

Is there any reliable way to check the (approximate) backup consumption and (approximate) deduplication rate of a VM in the datastore? I've read in this forum, that finding this information might be quite compute intensive, but as a run once in a troubleshooting case this might not matter - unless it would take days to complete obviously.

Ps. I hope this is no duplicate, but I was not able to find an answer to my question in the forum or any other information yet.
