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.
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
- Log on to the Security Center console.
- In the left-side navigation pane, choose .
- On the General Anti-ransomware Solutions page, click the Database extortion virus protection tab.
- 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.
- Log on to the Security Center console.
- In the left-side navigation pane, choose .
- On the General Anti-ransomware Solutions page, click the Database extortion virus protection tab.
- In the anti-ransomware policy list, find the anti-ransomware policy that you want
to edit and click Edit in the Actions column.
- In the Database protection strategy panel, change the value of Policy Name.
- Enter the username and password of your database account and click Next.
- 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:
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:
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 in the left-side navigation pane. On the
Anti-blackmail page, click
Upgrade below
Used Capacity /Total.
- 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.
- Log on to the Security Center console.
- In the left-side navigation pane, choose .
- On the General Anti-ransomware Solutions page, click the Database extortion virus protection tab.
- In the anti-ransomware policy list, find the anti-ransomware policy that you want
to delete and click the
icon in the Actions column.
- Select Delete from the drop-down list.
- 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.
- Log on to the Security Center console.
- In the left-side navigation pane, choose .
- On the General Anti-ransomware Solutions page, click the Database extortion virus protection tab.
- In the anti-ransomware policy list, find the anti-ransomware policy for which you
want to install the anti-ransomware agent, and click the
icon in the Actions column.
- 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.
- Log on to the Security Center console.
- In the left-side navigation pane, choose .
- On the General Anti-ransomware Solutions page, click the Database extortion virus protection tab.
- In the anti-ransomware policy list, find the anti-ransomware policy for which you
want to uninstall the anti-ransomware agent and click the
icon in the Actions column.
- Select Uninstall Client from the drop-down list.
- 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.
