Hello Commvault Community!
In one environment, we noticed that strange entries appeared in the logs regarding block pruning as part of deduplication:
SIDBPrune.log - from August 5, 2025

However, strangely enough, in another log from the previous day, we see that this chunk was deleted, and on August 5th, the system was still querying for it.

The CommCell Console GUI doesn’t show any block pruning delays, DataAging errors, or hanging data waiting to be deleted in the DiskLibrary structure. We're just wondering if this is a cause for concern or if this might be standard behavior for the Commvault system.
Thanks&Regards,
