After you create a protection policy, you can disable or edit the policy. If you no longer require the protection policy, you can delete it. This topic describes how to disable, edit, and delete a protection policy.

Prerequisites

A protection policy is created for your database. For more information, see Create a protection policy.

Background information

If the status of the protection policy is Successful, the policy takes effect. In this case, the data in your database is backed up based on the policy. If the status of the policy is Execution failed, we recommend you handle the exception at the earliest opportunity. For more information, see What do I do if the status of a protection policy is abnormal?

Enable or disable a 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 protection policy list, find the protection policy that you want to enable again or disable and turn on or turn off the switch in the Policy status column.
    • Disable a policy

      If you want to disable a protection policy, find the policy and turn off the switch in the Policy Status column.

      Notice After you disable the protection policy, the data backup task that runs based on the policy stops. Proceed with caution.
    • Enable a policy

      After a protection policy is enabled, the anti-ransomware client backs up the data in your database based on the policy. This protects your database against ransomware. To enable a protection policy, turn on the switch in the Policy status column.

Edit a protection policy

After a protection policy is created, you can edit the 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 protection policy list, find the protection policy that you want to edit and click Edit in the Actions column.
  5. In the Edit Policies 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 protection policy that you want to use. You can click Use recommendation policy to use the recommended protection 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 General Anti-ransomware Solutions page, click Upgrade below Used Capacity /Total.
  8. Click OK.
    The anti-ransomware client backs up the data in your database based on the new policy.

Delete a protection policy

If you no longer require a protection 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 protection policy list, find the protection 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 protection policy is deleted.
