    Cloud Backup:Restore an ECS instance

    Last Updated:Sep 21, 2023

    If a system failure occurs or an unexpected operation is performed on an Elastic Compute Service (ECS) instance, you can use the clone or restore feature to restore the ECS instance to a specified point in time. This topic describes how to restore an ECS instance.

    Prerequisites

    A backup is created for the ECS instance. For more information, see Back up ECS instances.

    Important If a source ECS instance exists, you can directly restore the source ECS instance. If a source ECS instance is released, you can restore the ECS instance by cloning an ECS instance.

    Use the clone feature to restore an ECS instance

    If a system failure occurs or an unexpected operation is performed on an ECS instance, you can use the clone feature to restore the ECS instance to a specified point in time.

    1. Log on to the Cloud Backup console.

    2. In the left-side navigation pane, choose Back Up > ECS Server Backup.

    3. In the top navigation bar, select a region.

    4. Click the Backed-up ECS Instances tab.
    5. Click the jia icon in front of the ECS instance.
    6. On the Instance Protection tab, click a backup and then click Clone.
    7. In the Create ECS Instance from Backup panel, enter a hostname and an instance name, and then select a VPC and a vSwitch.
    8. Click Create.
      Note You are charged for the new ECS instance based on the billing rules of ECS. For more information, see Pay-as-you-go.
      After you create the ECS instance, you can view the clone progress on the Jobs tab.

    Directly restore an ECS instance

    If a system failure occurs or an unexpected operation is performed on an ECS instance, you can use a backup to restore the ECS instance to a specified point in time.

    1. Log on to the Cloud Backup console.

    2. In the left-side navigation pane, choose Back Up > ECS Server Backup.

    3. In the top navigation bar, select a region.

    4. Click the Backed-up ECS Instances tab.
    5. Click the Plus sign icon in front of the ECS instance.
    6. On the Instance Protection tab, click a backup and then click Restore.
      Important You can restore an ECS instance only when the ECS instance is stopped and no backup is being created for the ECS instance. After a protected disk is restored to a specified point in time, the data that is written to the disk after the point in time is cleared. Proceed with caution.
    7. In the message that appears, click OK.
      After you create the restore job, you can view the progress on the Jobs tab.
