Cloud Backup:Add a data source

Usage notes

If the ECS instance with the backup client is in the same region as the CPFS file system, set the data network to VPC when you create a client group.

1. In the Actions column for the target client, click Settings.

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

Procedure

1. On the CPFS Backup page, select the region at the top and then add a data source in one of the following ways:

   • Through the CPFS backup wizard: In the CPFS backup wizard area at the top of the page, click Add Data Source.

   • On the CPFS Data Source tab: Click the CPFS Data Source tab, and then click Create Data Source.

   Note

   If you are using the previous console version (which displays Try New Version in the upper-right corner), click Create Data Source on the Data Source List tab.

2. In the Create Data Source panel, configure the following parameters.

   Cloud Parallel File Storage (CPFS) and CPFS for Lingjun support automatic mounting for backups. Other large-scale file systems require manual mounting.

   Cloud Parallel File Storage (CPFS)

   Parameter	Description
   Source Type	Select Cloud Parallel File Storage (CPFS).
   Data Source Name	Enter a descriptive name for the data source. For example, cpfs-datasource.
   Protocol Type	CPFS-NFS (This is a fixed value and does not need to be selected).
   CPFS Endpoint	The endpoint of the NFS export directory, for example, file-system-id.region.cpfs.aliyuncs.com. Note Create an export directory for the NFS protocol service in the CPFS console to generate a mount target before you enter this address.
   CPFS Shared Directory	The CPFS shared directory. The format is /share/yourpath.
   Mount Options	You can click Enter the values of the default CPFS-NFS mount parameters., or Set Mount Parameters manually.
   Backup Client Group	Select the clients that have the backup client installed. You can add multiple clients to a backup client group to run a backup job concurrently. Create Backup Client Group: Click Create Backup Client Group, specify a Client Group Name, and select the clients to add to the group. Select Backup Client Group: If the client you want to select has already been added to a group, you can select the existing client group. Important Ensure that the CPFS-NFS client is installed on every client machine in the client group. Note The status of a healthy client should be Activated. If the status is abnormal, see Install a backup client to troubleshoot. To save on public network costs by using a VPC or a VPN connection for backups, you can change Data Network from Internet to VPC in the Client Settings. For detailed instructions on installing the client, see Install a backup client.

   CPFS for Lingjun

   Important

   Contact the CPFS team to confirm that the CPFS for Lingjun file system can be mounted on each ECS instance in your selected client group.

   Parameter	Description
   Source Type	Select CPFS for Lingjun.
   Data Source Name	Enter a descriptive name for the data source. For example, cpfs-datasource.
   VPC Mount Target	The endpoint of the mount target. For example, cpfs-xxx.region.cpfs.aliyuncs.com. Note If you have not created a VPC mount target, contact the CPFS team to create one.
   CPFS Shared Directory	The shared directory exported from the VPC mount target of the CPFS for Lingjun file system. The default value is /.
   Backup Client Group	Select the client machines where you have installed the backup client. You can add multiple clients to a backup client group to run a backup job concurrently. Create Backup Client Group: Click Create Backup Client Group, specify a Client Group Name, and select the clients to add to the group. Select Backup Client Group: If the client you want to select has already been added to a group, you can select the existing client group. Note The status of a healthy client should be Activated. If the status is abnormal, see Install a backup client to troubleshoot. To save on public network costs by using a VPC or a VPN connection for backups, you can change Data Network from Internet to VPC in the Client Settings. For detailed instructions on installing the client, see Install a backup client.

   Other large file systems

   Parameter	Description
   Source Type	Select Other large-scale file systems.
   Data Source Name	Enter a descriptive name for the data source. For example, cpfs-datasource.
   Data Source Path	The file path of the data source on the backup client node. For example, /mnt/cpfs. Important If you use multiple backup nodes to back up the same CPFS file system, you must mount the file system to the same directory on each backup node. If the mount paths are different, the backup will fail.
   Backup Client Group	Select the client machines where you have installed the backup client. You can add multiple clients to a backup client group to run a backup job concurrently. Create Backup Client Group: Click Create Backup Client Group, specify a Client Group Name, and select the clients to add to the group. Select Backup Client Group: If the client you want to select has already been added to a group, you can select the existing client group. Note The status of a healthy client should be Activated. If the status is abnormal, see Install a backup client to troubleshoot. To save on public network costs by using a VPC or a VPN connection for backups, you can change Data Network from Internet to VPC in the Client Settings. For detailed instructions on installing the client, see Install a backup client.

3. Click OK.

   After you add the data source, it appears on the CPFS Data Source tab. Then, create a backup plan to back up the data source periodically.
