Use directions
Tencent Cloud provides the following two methods for you to create snapshots:
Manual snapshot: Manually back up the data of a CFS file system at any point in time as a snapshot, which can be used to create more identical file systems or, in the future, restore the file system to its state at that point in time. For more information, see Creating Snapshots.
Scheduled snapshot: If your business data changes frequently, you can use scheduled snapshots to provide continuous data backups. To achieve continuous backups of file system data over a certain time period, you only need to configure snapshot policy and associate it with file systems, significantly enhancing data security. For more information, see Scheduled Snapshot.
