What Should I Do If It Is Slow to Create ECSs Using a Full-ECS Image?

Symptom

When a full-ECS image created using a CSBS backup was used to create ECSs, the process was time-consuming or the system displayed a message, indicating that this image cannot be used to rapidly create ECSs.

Cause Analysis

The original backup format provided by CSBS cannot be used to rapidly create ECSs. Therefore, if your full-ECS image is in the original backup format, this issue occurs.

NOTE:

CSBS has provided a new backup format. This issue is resolved if you use a full-ECS image created using a CSBS backup in the new format.

Solution

If you want to use a full-ECS image to rapidly create ECSs, ensure that the full-ECS image is created using a CSBS backup in the new format. The procedure is as follows:

  • Scenario 1: The ECS based on which the target CSBS backup is created is still available.

    Back up the original ECS on the Cloud Server Backup Service page and use the new backup to create a full-ECS image. The created full-ECS image can be used to rapidly create ECSs.

    • For instructions about how to back up an ECS, see Cloud Server Backup Service User Guide.
    • For instructions about how create a full-ECS image, see Image Management Service User Guide.
  • Scenario 2: The ECS based on which the target CSBS backup is created is unavailable.
    1. Use the full-ECS image to create a new ECS.
    2. Back up the ECS.

      For details, see Cloud Server Backup Service User Guide.

    3. Use the CSBS backup to create a full-ECS image again.

      For details, see Image Management Service User Guide.

      The created full-ECS image can be used to rapidly create ECSs.
