The Unusual file activity panel displays information about anomalous activity on the file systems of active client computers and in backup jobs. With this panel, you can view file path information for the anomalies and track anomaly trending information. Then, you can recover the most recent good version of anomalous files or recover the entire client as a virtual machine, from before the anomalous behavior. This panel provides a single location for identifying and acting on potential threats with quick and safe recovery options.
Unusual file activity occurs when a large number of files are created, deleted, modified, or renamed on a client computer, or when the number of created, modified, or deleted files in a backup job suddenly increases or decreases. These situations might indicate the presence of ransomware or other types of threats.
The anomaly thresholds are based on historical activity and machine-learning algorithms to reduce false positives from typical activity on the file system. These activities are monitored by default. To receive alerts when abnormal activities are detected, configure the File Activity Anomaly Alert.
Where to Access the Panel
You can view the Unusual file activity panel in the Command Center.
Note: To view the Unusual file activity panel, both the client and the CommServe computer need to be at Feature Release 11.23 or higher.
Who Can View the Panel
The Unusual file activity panel for file and backup job anomalies is available to tenant administrators as well as to users who have the necessary permissions on the client computer with the anomaly.
What Is Monitored
Windows clients that have the file system package installed can be monitored for unusual activity on the file systems and in backup jobs.
Linux clients can be monitored for unusual activity in backup jobs.
Network shares can be monitored for unusual activity in backup jobs.
VSA and non-file system clients can be monitored if the file system package is installed in restore-only mode.
