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.
  2. In the left-side navigation pane, choose Defense > Anti-ransomware.
  3. On the General Anti-ransomware Solutions page, click the Database extortion virus protection tab.
  4. In the anti-ransomware policy list, 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.
  2. In the left-side navigation pane, choose Defense > Anti-ransomware.
  3. On the General Anti-ransomware Solutions page, click the Database extortion virus protection tab.
  4. In the anti-ransomware policy list, find the anti-ransomware policy that you want to edit and click Edit in the Actions column.
  5. In the Database protection strategy panel, change the value of Policy Name.
  6. Enter the username and password of your database account and click Next.
  7. Configure the parameters.
    The following table describes the parameters.
    Parameter Description
    Protection Policies Select 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.
    Full backup strategy Select the interval at which full backup is performed and the time at which the full backup task starts. Units of the interval:
    • Hours
    • Day(s)
    • Week
    Note 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 Select the interval at which incremental backup is performed and the time at which the incremental backup task starts. Units of the interval:
    • Hours
    • Day(s)
    • Week
    Note Incremental backup indicates that you back up only the data that is newly generated or modified after the last full or incremental backup task. Therefore, incremental backup is time-saving and requires less anti-ransomware capacity.
    Backup data retention time Select the retention period of the backup. Valid values:
    • 1day
    • 2days
    • 3days
    • 4days
    • 5days
    • 6days
    • 7days
    Backup network bandwidth limit Enter the maximum network bandwidth that is allowed during data backup. If you set this parameter to 0, network bandwidth is unlimited.
    Note By default, backup data is stored in three copies. As a result, the anti-ransomware capacity that is required is equal to the size of backup data multiplied by three. Insufficient anti-ransomware capacity leads to backup failures. To prevent backup failures, we recommend that you purchase additional anti-ransomware capacity. To purchase additional anti-ransomware capacity, perform the following operations: Log on to the Security Center console and choose Defense > Anti-ransomware in the left-side navigation pane. On the Anti-blackmail page, click Upgrade below Used Capacity /Total.
  8. Click Finished.
    The anti-ransomware agent backs up the data in your database based on the new anti-ransomware policy.

Delete an anti-ransomware policy

If you no longer need an anti-ransomware policy, you can delete it.

  1. Log on to the Security Center console.
  2. In the left-side navigation pane, choose Defense > Anti-ransomware.
  3. On the General Anti-ransomware Solutions page, click the Database extortion virus protection tab.
  4. In the anti-ransomware policy list, find the anti-ransomware policy that you want to delete and click the More icon icon in the Actions column.
  5. Select Delete from the drop-down list.
  6. In the message that appears, click OK.
    Wait until the anti-ransomware policy is deleted.

Manually install the anti-ransomware agent

If an anti-ransomware policy for a database fails to be initialized or you have manually uninstalled the anti-ransomware agent from the server on which the anti-ransomware policy takes effect, you can manually install the anti-ransomware agent on the server.

  1. Log on to the Security Center console.
  2. In the left-side navigation pane, choose Defense > Anti-ransomware.
  3. On the General Anti-ransomware Solutions page, click the Database extortion virus protection tab.
  4. In the anti-ransomware policy list, find the anti-ransomware policy for which you want to install the anti-ransomware agent, and click the More icon icon in the Actions column.
  5. Select Install the client from the drop-down list.
    The value of Client status for the anti-ransomware policy changes to Installing. The anti-ransomware agent is installed in about 5 minutes.

Manually uninstall the anti-ransomware agent

Notice After you uninstall the anti-ransomware agent, the anti-ransomware policy that is created for your database no longer backs up the data of your database, and your database is not protected from ransomware. Proceed with caution.
  1. Log on to the Security Center console.
  2. In the left-side navigation pane, choose Defense > Anti-ransomware.
  3. On the General Anti-ransomware Solutions page, click the Database extortion virus protection tab.
  4. In the anti-ransomware policy list, find the anti-ransomware policy for which you want to uninstall the anti-ransomware agent and click the More icon icon in the Actions column.
  5. Select Uninstall Client from the drop-down list.
  6. In the message that appears, click OK.
    The value of Client status for the anti-ransomware policy changes to Uninstalling. The anti-ransomware agent is uninstalled in about 5 minutes.
