Cloud Backup:Install a Cloud Backup client

Installation path

Large-scale file systems are generally designed to process and store large amounts of data and provide high throughput, high concurrency, and high availability. To back up a large-scale file system, you must perform the following operations:

1. Prepare one or more physical or virtual machines as backup nodes, and then mount the large-scale file system on these nodes. The mount path for each backup node must be the same, for example, /mnt/cpfs. You must set the Data Source Path parameter to this mount path when you add a data source.

2. Install a Cloud Backup client on each backup node of the file system. You can manage multiple Cloud Backup clients installed on multiple nodes as a client group to improve backup and restoration performance.
