You can use Cloud Backup to back up and recover files in a CPFS General-purpose Edition file system. Before you begin, you must install a backup client on the backup node of the CPFS General-purpose Edition file system. To improve backup and recovery performance, you can install multiple backup clients as a client group.

Warning

Before you install or uninstall a client, check the installation path:

  • If a CPFS folder is mounted to the installation path, unmount the folder to avoid the accidental deletion of CPFS files.

  • If other important folders or files exist in the installation path, move them to another folder to avoid accidental deletion.

Prerequisites

To back up data, you need the following:

  • One or more physical machines, virtual machines, or ECS instances are required to serve as backup nodes. These nodes must have network connectivity to the CPFS General-purpose Edition file system.

  • Before you back up a file system that is mounted by a CPFS-NFS client, ensure that the CPFS-NFS client is installed on all ECS instances that are used for the backup. For more information, see Mount a file system on a CPFS-NFS client (Recommended).
