Hello
It sounds more like DDB Baseline (unique data written for deduplocation). We don’t prune Baseline data even if it’s past retention. We only prune the data once all jobs referencing it have also aged. Since deduplication builds references off of written data to save space on future backups, we cannot prune the physical data until the jobs no longer reference it. You can refer to the link below for more information.
If you check SIDBPrune.log on the MediaAgent(s) associated to the Cloud Library, do you see any errors? Is S3 reporting a different amount of space consumed than Commvault is?

Hello
Commvault does collect metadata from S3. We use the cURL API code and send GET requests.
Is there a specific “query” you are referring to? Or any issue you are seeing?
Thank you,
