    Cloud Parallel File Storage:Add a data source

    Last Updated:Jul 03, 2025

    Cloud Backup client provides the Cloud Parallel File Storage (CPFS) backup feature. You can back up the data from a CPFS file system to a backup vault of Cloud Backup. After you install a Cloud Backup client, you must add a data source in the Cloud Backup console.

    Prerequisites

    • Cloud Backup is activated. You are not charged for activating Cloud Backup. If you use the CPFS backup feature of Cloud Backup, you are charged for the storage usage of backup vaults. For more information, see Billing of the CPFS backup feature.

    • The CPFS file system can access Alibaba Cloud over the Internet. If Internet access is unavailable, make sure that the CPFS file system is connected to Alibaba Cloud virtual private clouds (VPCs) by using virtual private networks (VPNs) or Express Connect circuits. You must also make sure that you can use a Cloud Backup client to access one of the following CIDR blocks from an on-premises server: 100.64.0.0/10, 100.64.0.0/11, and 100.96.0.0/11. For more information, see Connect a VPC to a data center in single-tunnel mode.

    • A Cloud Backup client is installed on each backup node. For more information, see Install a Cloud Backup client.

    • The data source path for backup is prepared. Example: /mnt/cpfs.

    • You have created a file system and managed VPC mount targets, and obtained the VPC mount target address. For more information about how to mount a CPFS For Lingjun file system, contact the CPFS team.

    Important

    • Backup jobs consume resources such as CPU and memory and affect the performance of your Elastic Compute Service (ECS) instance. We recommend that you create a dedicated ECS instance to run backup jobs.

    • The new ECS instance must reside in the same VPC as the source file system CPFS for Lingjun. Creating an ECS instance incurs fees, which are included in your ECS bills. For more information, see Instance types.

    • Before you back up a CPFS for Lingjun file system, contact the CPFS team to make sure that the CPFS for Lingjun file system can be mounted on the ECS instances where the client is installed.

    Usage notes

    If the ECS instance on which a Cloud Backup client is installed resides in the region where you use the CPFS backup feature, set the data network to VPC when you create a client group.

    1. Click Settings in the Actions column of the Cloud Backup client that you want to configure.

    2. In the Client Settings dialog box, set Data Network to VPC and click OK.

    Procedure

    Note

    After you create a backup plan, the first backup job performs a full backup and subsequent backup jobs perform incremental backups.

    1. Log on to the Cloud Backup console.

    2. In the left-side navigation pane, choose Backup > CPFS Backup.

    3. In the top navigation bar, select a region.

    4. On the CPFS Backup page, click Create Data Source.

    5. In the Create Data Source panel, configure the parameters and click OK.

      Parameter

      Description

      Source Type

      CPFS for Lingjun.

      Data Source Name

      The name of the CPFS data source. The name helps you quickly identify the data source. You can specify a name based on your business requirements. Example: cpfs-datasource.

      VPC Mount Target

      The domain name of the mount target. Example: cpfs-xxx.region.cpfs.aliyuncs.com.

      CPFS Shared Directory

      The shared directory that is exported from the VPC mount target of the CPFS for Lingjun file system. Default value: /.

      Backup Client Group

      Select the hosts on which you have installed the Cloud Backup client.

      If you want multiple Cloud Backup clients to concurrently run a backup job, you can add the clients to a client group.

      • Create Backup Client Group: Click Create Backup Client Group, enter a name in the Client Group Name field, and select the clients that you want to add to the client group.

      • Select Backup Client Group: If the clients that you want to select have been added to an existing client group, select the client group.

      Note

      • The status of a normal client is Activated. If the status is abnormal, see Install a Cloud Backup client.

      • If you want to save costs during backup without using the Internet, you can change Data Network from Internet to VPC in Client Settings after you establish a VPC or VPN connection.

      For more information about how to install a Cloud Backup client, see Install a Cloud Backup client.

      After the data source is added, you can view the added data source on the Data Source List tab. At this time, None is displayed in the Backup Plans column. You can then create a backup plan for the data source. For detailed steps, see Create Backup Plan.
