Full-machine restore of VMware virtual machines on the cloud

Step 1: Restore to ECS

1. Log on to the Cloud Backup console. In the navigation pane on the left, choose Backup > VMware Backup and Disaster Recovery. In the top navigation bar, select the region where your resources are located.

2. On the Backup Jobs tab, find the backup job for the target virtual machine and click Restore to ECS in the Actions column.

3. In the Create ECS Image dialog box, configure the virtual machine to restore and the intermediate instance.

   1. On the VMs to Restore tab, select the virtual machine that you want to restore and click Next.

   2. On the Configure Intermediate Instance tab, configure the parameters for the intermediate instance as described in the following table.

      Parameter	Description
      Hostname	The hostname of the target ECS instance. For Windows: 2–15 characters. Use uppercase or lowercase letters, digits, or hyphens (-). Do not start or end with a hyphen. Do not use only digits. For Linux and other systems: 2–64 characters. You can use periods (.) to separate the name into multiple segments. Each segment can contain uppercase or lowercase letters, digits, or hyphens (-). Do not start or end with a period or hyphen.
      Instance Name	The name of the intermediate ECS instance. After restore completes, this becomes the name of the target ECS instance. Maximum length: 128 characters.
      VPC	Select a VPC from the VPC list to use during restore.
      vSwitch	Select a vSwitch from the vSwitch list to use during restore. The zone of the vSwitch determines which ECS instance types are available.
      Instance Family	The type of the intermediate ECS instance. Options include General-purpose, Compute-optimized, Memory-optimized, High frequency, or Other. Your selection updates the available instance specifications below.
      Instance Type	The specifications of the intermediate ECS instance. For details, see Overview of ECS instances. Note If the source instance uses UEFI boot, choose an ECS instance of Generation 7 or later. Otherwise, the instance might fail to start.
      Disk Type	The storage class of the intermediate ECS instance. Options include Ultra Disk and Standard SSD. Note All disks from the VM will use the same disk type. Only disks larger than 40 GB support AutoPL.
      Security Group	Select a security group from the Security Group list to use during restore.
      IP Address Type	The method for assigning a private IP address to the target ECS instance. Choose DHCP for automatic assignment, or choose Manual and enter an IP address.
      Operating System Type	The system automatically detects and displays the operating system type of the source virtual machine. No manual configuration is needed.
      Start System After Restore	Whether to automatically start the target ECS instance after restore completes. Enabled by default.
      Assign Public IP	Whether to assign a public IP address to the target ECS instance. Disabled by default.

4. Click OK.

   On the Restore Jobs tab, change the job type to Cloud Restore Jobs to monitor the progress of the restore job. The restore process includes the following stages:

   • Pending: The system is preparing the restore environment.

   • Running: The data is being transferred from the backup vault to the intermediate instance. The page displays the progress and restore speed.

   • Completed: The restore job is successful and the intermediate instance is automatically released. The Destination column displays the name and instance ID of the destination ECS instance.

   Note

   The time required to complete the restore job depends on factors such as the backup data size and network conditions.

Step 2: (Optional) Handle a failed restore

If the restore job fails, its status changes to Failed and the related image information is displayed. In this case, the system has created an ECS image but failed to create an ECS instance. You can use the image to manually create an ECS instance:

1. Go to the Images page of the ECS console. On the Custom Images tab, find the image whose name contains the restore job ID. The image is named in the format of restore-{VM name}-hbr-{restore job ID}.

2. In the Actions column of the image, click Create Instance.

3. On the Custom Launch tab, the system automatically specifies the region and image. Configure the other configuration items as prompted and click Confirm Order.

Step 3: Post-restore validation and resource cleanup

The destination ECS instance that is created from the restore job is billed on a pay-as-you-go basis. We recommend that you validate your workload and release unnecessary resources in a timely manner to avoid incurring unwanted fees.

• Validate the workload: Use a remote connection tool, such as Remote Desktop Protocol (RDP) for Windows or Secure Shell (SSH) for Linux, to log on to the destination ECS instance and verify the integrity of the system and business data.

• Release resources: If the restore job is performed only for validation or testing, release the instance in the ECS console to avoid unnecessary charges.

• Delete images (for failed restore jobs only): If you manually created an ECS instance in Step 2, you can delete the unnecessary images on the Custom Images tab of the ECS console. When you delete an image, we recommend that you also delete its associated snapshots.
