Backing Up ECS Data

Scenarios

ECS data can be backed up using Cloud Server Backup Service or Volume Backup Service.
  • CSBS (recommended): Use this backup method if you want to back up the data of all EVS disks on an ECS, including the system disk and data disks. This prevents data inconsistency caused by time difference in creating a backup.
  • VBS: Use this backup method if you want to back up the data of one or more EVS disks (system disk or data disk) on an ECS. This minimizes backup costs on the basis of data security.

For Windows ECSs, you can install the Windows Server Backup tool provided by the Windows OS to back up full ECS data. You are advised to use VBS and CSBS provided by the public cloud.

CSBS Backup Procedure

  1. Log in to the management console.
  2. Click in the upper left corner and select the desired region and project.
  3. Under Computing, click Elastic Cloud Server.

    The Elastic Cloud Server page is displayed.

  4. In the navigation pane one the left, choose Cloud Server Backup Service.
  5. Click Create CSBS Backup.
  6. Back up the ECS data as prompted.

    For more information, see Cloud Server Backup Service User Guide.

NOTE:

After a CSBS backup is created, you can use it to create an image and use the image to create ECSs in a batch for rapidly restoring the service running environment. To do so, perform the following operations:

  1. Create a CSBS backup on the Cloud Server Backup Service page.
  2. Use the CSBS backup to create a private image (full-ECS image).
  3. Use the full-ECS image to create ECSs in a batch.

For more details about how to use CSBS backups to create images, see section "Using Backups to Create Images" in Cloud Server Backup Service User Guide and section "Creating a Full-ECS Image Using a CSBS Backup" in Image Management Service User Guide.

VBS Backup Procedure

  1. Log in to the management console.
  2. Click in the upper left corner and select the desired region and project.
  3. Under Computing, click Elastic Cloud Server.

    The Elastic Cloud Server page is displayed.

  4. In the navigation pane on the left, choose Volume Backup Service.
  5. Click Create VBS Backup.
