If the data on your servers has been encrypted by ransomware, you can create restoration tasks to restore the encrypted data and reduce losses. This topic describes how to create a restoration task.


Before your servers are intruded by ransomware, a protection policy is created and server data can be backed up as expected based on the protection policy. When you create a restoration task, make sure the following requirements are met:
  • The value of recoverable versions in the protection policy is not zero.
  • The Security Center agent is enabled.

Background information

Security Center backs up the server data based on the protection policy you have created. If you have used the recommended policy, you can select a version that has been backed up to restore the data on the current server.


  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 target protection policy that is applied to a restoration task, and then click The hide/show icon.
  5. Find the target server where data will be restored, and click Restore in the Actions column.Restore
    You can also click the number in the Recoverable Versions column to go to the Restoration page.The Recoverable Versions column
  6. On the Restoration page, set the following parameters: Select a restored version, Select a restored file, and Recovery directory address.Create a restoration task
    Sample values of the Recovery directory address parameter in a Windows and Linux system are as follows:
    • Windows: D:\Documents\Restore
    • Linux: /home/Restore
    Note The Recovery directory address parameter specifies the target folder where you want to restore the server data. The backup data is restored in the cloud. After you create a restoration task, the files will be restored to the Recovery directory address. If the specified directory does not exist, Security Center cannot perform the restoration task. We recommend that you specify a valid directory.
  7. Click OK.
    After you create a restoration task, you will receive this message: The Restore task is created.
