Manage an anti-ransomware policy

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.
