important

This topic contains important information on necessary precautions. We recommend that you read this topic carefully before proceeding.

You can use Cloud Backup to back up files in the Cloud Parallel File Storage (CPFS) for Lingjun and restore them when needed. Before this, you need to install the backup client on the backup nodes of the CPFS for Lingjun file system. You can add multiple Cloud Backup clients to a client group to improve backup and restoration performance.

Warning

Before you install and uninstall a Cloud Backup client, check the client installation path:

If a CPFS directory is mounted to the installation path, unmount the CPFS directory. This prevents files from being accidentally deleted.
If other important directories and files exist in the installation path, move them to another path. This prevents these directories and files from being accidentally deleted.

Prerequisites

To facilitate backup, you need to:

Prepare one or more physical machines, virtual machines, or Elastic Compute Service (ECS) instances as backup nodes. Ensure network connectivity between the backup nodes and the CPFS for Lingjun file system.
Contact CPFS technical support to confirm that CPFS for Lingjun file systems can be mounted on each ECS instance that you use for backup.
