Cloud Backup:Install a Cloud Backup client

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 another large-scale file system).

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

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.

Usage notes

• To achieve the optimal backup performance, we recommend that you run a Cloud Backup client on a host with the following configurations: 64-bit CPU with two or more cores and more than 8 GB available memory.

• The volume of data that can be backed up depends on the available memory. For a host with 4 GB available memory, a maximum of one million files, up to 8 TB in total, can be backed up. If you want to back up tens of millions of files, we recommend that you prepare 16 GB available memory.

• The installation package of a Cloud Backup client (64-bit) does not support the ARM64 architecture.

• 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 use Cloud Backup, we recommend that you read the topics about the limits on Cloud Backup, the default backup speed, and the features available in each region. For more information, see Limits, Backup and recovery speeds, Features, and Features available in each region.
