If the data in your database is encrypted by ransomware, you can create a restoration task to restore the encrypted data and reduce loss. This topic describes how to create a restoration task and view the status of the restoration task.

Prerequisites

  • An anti-ransomware policy is created for your database and is enabled. Data can be backed up based on the policy.
  • The number of backup versions is not zero.

Procedure

  1. Log on to the Security Center console.In the left-side navigation pane, choose Protection Configuration > Host Protection > Anti-ransomware.
  2. In the anti-ransomware policy list of the Database extortion virus protection tab, find the database whose data you want to restore and click Restore in the Actions column.
  3. In the Restoration dialog box, configure the parameters.
    The parameters vary based on database engines.
    Notice If you have a server that runs the same operating system as the original server hosting the database and a protection server is protected for the server, you can restore your data to the server. However, you cannot restore the data to a server that runs a different operating system from the original server.
    • Parameters required to restore the data in MySQL databases
      Parameter Description
      Recovery time point The time at which the selected backup is generated. If the data in your database is encrypted by ransomware, you can select the last backup version before the encryption. This way, the restored data is similar to the data before the encryption.
      Restore to server The server to which you want to restore your data.
    • Parameters required to restore the data in SQL Server databases
      Parameter Description
      Change database The database whose data you want to restore.
      List of stored backups The backup that you want to use to restore data. If the data in your database is encrypted by ransomware, you can select the last backup version before the encryption. This way, the restored data is similar to the data before the encryption.
      Restore to server The server to which you want to restore your data.
    • Parameters required to restore the data in Oracle databases
      Parameter Description
      Select recovery version The version of the backup that you want to use to restore data. The value of this parameter is a time range in which the data is backed up.
      Recovery time point The time at which the selected backup is generated. You can set this parameter to any time within the time range in which the data is backed up.
      Restore to server The server to which you want to restore your data.
  4. Click OK.
    The anti-ransomware agent runs the restoration task.
    Notice If a data backup task and a restoration task are running on the server that you specify at the same time, the restoration task fails. We recommend that you stop the data backup task that is running on the server before you create a restoration task.

View a restoration task

You can view a restoration task in the Recovery record panel. To go to the panel, click the value below Recovering / Recovering Records on the Database extortion virus protection tab. After the restoration task is complete, the value in the Recovery Status column changes to Successful in the Recovery record panel.
