Restore a CPFS file system - Cloud Backup - Alibaba Cloud Documentation Center

After you back up files from a Cloud Parallel File Storage (CPFS) file system to a backup vault by using Cloud Backup, you can restore the files based on historical backup points if the files are lost or damaged. You can restore all backup files or files that meet the specified conditions. You can restore backup files to the source CPFS file system or restore backup files to a new CPFS file system.
