After you create an anti-ransomware policy, you can disable or edit the anti-ransomware policy. If you no longer need the anti-ransomware policy, you can delete it. This topic describes how to disable, edit, and delete an anti-ransomware policy. This topic also describes how to manually install and uninstall the anti-ransomware agent.

Prerequisites

An anti-ransomware policy is created for your database. For more information, see Create an anti-ransomware policy

Background information

If the status of the anti-ransomware policy is Successful, the anti-ransomware policy takes effect. In this case, the data in your database is backed up based on the anti-ransomware policy. If the status of the anti-ransomware policy is Execution failed, we recommend you handle the exception at the earliest opportunity. For more information, see Troubleshoot the issues causing the abnormal status of an anti-ransomware policy for a database.

Enable or disable an anti-ransomware policy

  1. Log on to the Security Center console.In the left-side navigation pane, choose Protection Configuration > Host Protection > Anti-ransomware.
  2. In the anti-ransomware policy list of the Database extortion virus protection tab, find the anti-ransomware policy that you want to enable or disable and turn on or turn off the switch in the Policy status column.
    • Disable an anti-ransomware policy

      To disable an anti-ransomware policy, find the anti-ransomware policy and turn off the switch in the Policy status column.

      Notice After you disable the anti-ransomware policy, the data backup task that runs based on the anti-ransomware policy stops. Proceed with caution.
    • Enable an anti-ransomware policy

      The anti-ransomware agent can back up the data in your database based on an anti-ransomware policy only after the anti-ransomware policy is enabled. This protects your database against ransomware. To enable an anti-ransomware policy, turn on the switch in the Policy status column.

Edit an anti-ransomware policy

After an anti-ransomware policy is created, you can edit the anti-ransomware policy.

  1. Log on to the Security Center console.In the left-side navigation pane, choose Protection Configuration > Host Protection > Anti-ransomware.
  2. In the anti-ransomware policy list of the Database extortion virus protection tab, find the anti-ransomware policy that you want to modify and click Edit in the Actions column.
  3. In the Database protection strategy panel, change the value of Policy Name.
  4. Enter the username and password of your database account and click Next.
  5. Configure the parameters.
    Parameter Description
    Protection Policies The anti-ransomware policy that you want to use. You can click Use recommendation strategy to use the recommended anti-ransomware policy that is provided by Security Center. If the recommended anti-ransomware policy cannot meet your business requirements, you can modify the policy.
    Full backup strategy The interval at which full backup is performed, the days of a week on which full backup is performed, and the point in time at which the full backup starts.

    Full backup indicates that you back up all data that exists at a specific point in time. Full backup is time-consuming and requires a large amount of anti-ransomware capacity.

    Incremental backup strategy The interval at which incremental backup is performed and the point in time at which the incremental backup starts.

    Incremental backup indicates that you back up only the data that is newly generated or modified after the last full or incremental backup. Therefore, incremental backup is time-saving and requires less anti-ransomware capacity.

    Backup data retention time The retention period of the backup.
    Backup network bandwidth limit The maximum network bandwidth that is allowed during data backup. If you set this parameter to 0, network bandwidth is unlimited.
  6. Click Finished.
    The anti-ransomware agent backs up the data in your database based on the new anti-ransomware policy.
