After you create a protection policy, you can enable or disable it. You can also change the policy name, associated assets, and protected directory addresses. If a protection policy is no longer required, you can delete it. This topic describes how to enable, disable, edit, and delete a protection policy. This topic also describes how to manage servers that are added to a protection policy.

Prerequisites

An anti-ransomware policy is created. For more information, see Create a protection policy.

Background information

A protection policy takes effect only when the status of the protection policy is Normal. If the status of the protection policy is Exception, we recommend that you handle the exception in a timely manner. For more information, see What do I do if the status of a protection policy is abnormal?

Enable or disable a protection policy

  1. Log on to the Security Center console.
  2. In the left-side navigation pane, choose Defense > Anti-Virus.
  3. On the Anti-Virus page, click Add anti-ransomware policies.
  4. On the General Anti-ransomware Solutions page, find the policy that you want to enable or disable and turn on or off the switch in the Policy Status column to enable or disable the policy.
    • Enable a policy

      Security Center applies a protection policy to back up your server data only after the protection policy is enabled. You can turn on the switch in the Policy Status column to enable a protection policy.

    • Disable a policy
      Notice If a data restoration task is running based on the current protection policy, the restoration task stops when the policy is disabled. Before you disable the policy, we recommend that you verify that no restoration tasks are running based on the policy.

      If your servers do not need anti-ransomware, you can turn off the switch in the Policy Status column.

Edit a protection policy

  1. Log on to the Security Center console.
  2. In the left-side navigation pane, choose Defense > Anti-Virus.
  3. On the Anti-Virus page, click Add anti-ransomware policies.
  4. On the General Anti-ransomware Solutions page, find the protection policy that you want to edit and click Edit in the Actions column.Edit a protection policy
  5. In the Edit Policies pane, configure the parameters.Edit Policies tab
    For more information about the parameters, see Create a protection policy.
  6. Click OK.

Manage servers that are added to a protection policy

After you create a protection policy, you can add servers to or remove servers from the protection policy. You can also install or uninstall the anti-ransomware client on your servers.

  1. Log on to the Security Center console.
  2. In the left-side navigation pane, choose Defense > Anti-Virus.
  3. On the Anti-Virus page, click Add anti-ransomware policies.
  4. On the General Anti-ransomware Solutions page, find the protection policy that you want to apply to servers, and then click the Hide/Show icon icon.
  5. Manage the servers on which the protection policy takes effect.
    You can perform the following operations:
    • Add servers to the protection policy

      When you edit the protection policy, you can add servers to the protection policy. For more information, see Edit a protection policy.

      To ensure that the anti-ransomware protection capacity is effectively utilized, you can apply only one protection policy to each ECS instance. You can add a maximum of 100 ECS instances to each protection policy.

    • Remove servers from the protection policy
      Notice After a server is removed from the protection policy, Security Center no longer protects the server against ransomware and deletes all backup data of the server. Deleted backup data cannot be recovered. We recommend that you exercise caution when you remove servers from the protection policy.

      If you no longer need anti-ransomware for a server, click Delete in the Actions column, and click OK in the message that appears. If you want to remove multiple servers from a protection policy, select the servers and click Delete.

    • Install or uninsall an anti-ransomware client
      Notice
      • After the anti-ransomware client is uninstalled, Security Center deletes the server data that is backed up by the client. Deleted backup data cannot be recovered. We recommend that you exercise caution with the uninstallation of an anti-ransomware client.
      • After Security Center deletes the server data that is backed up by the client, it releases the corresponding anti-ransomware protection capacity. The anti-ransomware protection capacity is updated 12 to 48 hours after the release. We recommend that you wait for a sufficient amount of time before you recheck the anti-ransomware protection capacity.

      If you want to install or uninstall an anti-ransomware client on a server, click Install or Uninstall in the Actions column. If you want to install or uninstall the anti-ransomware client on multiple servers that are added to the same protection policy, select the servers and click Install or Uninstall.

Delete a protection policy

Notice After you delete a protection policy, the ongoing backup tasks that are based on the policy automatically stop, and the data that is backed up on the servers in the policy is deleted. Deleted backup data cannot be recovered. We recommend that you exercise caution when you delete a protection policy.
  1. Log on to the Security Center console.
  2. In the left-side navigation pane, choose Defense > Anti-Virus.
  3. On the Anti-Virus page, click Add anti-ransomware policies.
  4. On the General Anti-ransomware Solutions page, find the protection policy that you want to delete and click Delete in the Actions column.
  5. In the message that appears, click OK.
