    I am looking for more information regarding the Ransomware Protection option referenced in BOL: http://documentation.commvault.com/commvault/v11/article?p=features/disk_library/t_enable_ransomware_mediaagent.htm

    The documentation is very limited and we would like to understand more about what is happening with this option before we consider using it.

    Is this for Mount Paths that exist as part of the MediaAgent only (e.g. Local Disk, SAN Attached Disk)?

    Will it have any affect on NAS based mount paths? We have multiple MediaAgents that all have direct paths to a NAS based library. If one of those MediaAgents was able to somehow restrict the path for only their use, I would see that being an issue. I would guess this does not apply to NAS libraries, but I cannot find documentation to support it.

    Well that is indeed what it states and yes it will also work on NAS based mount paths. And I would be very happy if it would restrict the access to the mount path in the case of ransomware infection. Because if it happens it will have effect on the entire volume thus all MAs will be affected.

    When ransomware protection is enabled on an MA, any other applications like a ransomware running on these MAs will not be allowed modification/delete access to the files on the locally attached mount paths as well as network mount paths.

    To get the full protection of data on a network Mount path, the network share should have restricted permissions with a specific Commvault backup user that has write/modify/delete permission. This Commvault backup user credentials should be configured for Commvault disk library mount path and all MAs accessing this share should have the ransomware protection enabled.

    To reiterate, make sure that no other user, other than this specific backup user (not even an admin) has write/modify/delete permission on this network share.

    Note that this feature is applicable to only Windows MAs with V11 SP6 and higher.
