Ransomware Protection

Protecting Mount Paths from Ransomware

Make sure to protect all your mount paths from Ransomware so that the backup data (in storage) does not get affected by malicious Ransomware.

See Protecting Mount Paths From Ransomware for more information.

Ransomware Alerts and Events

NetApp software automatically detects the presence of Ransomware on your client computers. The Ransomware check happens once a day. If you want frequent checks at regular intervals, enable the nTimer_CheckForRansomware additional setting on the client computer. For instructions on adding the additional settings from the CommCell Console, see Add or Modify an Additional Setting.

NetApp software notifies the CommCell Console administrator immediately by sending an Alert and displaying an Event Message as follows:

  • The Ransomware Alert is by default configured to send out an alert to all the users included in the Master CommCell User Group.

    See Alerts and Notifications - Predefined Alerts for more information.

  • The following event message will also be displayed, if the NetApp software detects the presence of Ransomware on your computer:

    Detected a possible Ransomware attack. Please verify the data on the machine.

Recovering From a Ransomware Attack

Perform the following steps when Ransomware is detected in a client computer.

  1. Disable network connections to the affected client and make sure that the Ransomware is cleared.
  2. Disable all backups from the client.
    • From the CommCell Browser, right-click the Client and select Properties.
    • On the Activity Control tab, clear the Enable Backup check box.
    • Click OK.
  3. Enable network connections to the client once you are sure that the client is clean.
  4. Restore the necessary data from an older backup.

    See Restore Backup Data for more information.

  5. Enable all backups from the client.
    • From the CommCell Browser, right-click the Client and select Properties.
    • On the Activity Control tab, select the Enable Backup check box.
    • Click OK.
