The Unusual file activity report for file data-related anomalies summarizes the file data-related anomalies on backed up files gathered from all Windows clients that have Commvault Platform Release 2023E or a more recent platform release.
You can use this report to track different versions of a document to see if the file has been modified drastically. Modifications may occur if the file is encrypted or corrupted by malware attacks.
The anomaly check is performed on backup jobs that use File Indexing Version 2.
