You can enable ransomware protection on a Windows MediaAgent.
For all the Windows MediaAgents that have access to a disk library mount path, ransomware protection is enabled by default.
However, for Linux MediaAgents that have access to a disk library mount path, you must enable ransomware protection manually. For instructions, see Ransomware Protection for Disk Libraries on a Linux MediaAgent.
From the navigation pane, go to Manage > Infrastructure.
The Infrastructure page appears.
Click the MediaAgents tile.
The MediaAgents page appears.
Click the MediaAgent.
In the Control section, move the Ransomware protection toggle key to the right.
For a Linux MediaAgent, the toggle key is disabled and displays the status of ransomware protection.
Administrative shares pose a security vulnerability and if you have an existing disk library mount path configured to use an administrative share, reconfigure the share using a dedicated share. For more information, see Reconfiguring Mount Paths that Use Administrative Share.
