    Cloud Backup:Install a Cloud Backup client

    Last Updated:Sep 05, 2024

    You can use Cloud Backup to back up files in a Cloud Parallel File Storage (CPFS) file system and restore the files when needed. Before you back up files, install a Cloud Backup client on each backup node of the CPFS 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.

    Before you begin

    To back up a CPFS file system, you must perform the following operations:

    1. Prepare one or more physical machines, virtual machines, or Elastic Compute Service (ECS) instances as backup nodes. You must ensure network connectivity between the backup nodes and your file system (CPFS file system, CPFS for Lingjun file system, or other large-scale file system).

    2. Before you back up a CPFS file system, make sure that a CPFS-NFS client is installed on all ECS instances.

    3. Before you back up a CPFS for Lingjun file system, contact the CPFS team to confirm that all ECS instances used as backup nodes can be mounted with CPFS.

      4. Configure the logon identity.

        Files in a CPFS file system are shared over a network. To back up or archive files in a CPFS file system, select This user as the logon identity. The user must meet the following requirements:

        • The user has the permissions of the local administrator.

        • The user has the permissions to log on as a service.
