1. Select an instance, then click [More Actions]-[Create a Snapshot]
2. Enter your snapshot name and select whether to save memory information.
3. Click the [Manage], and you will view the snapshot in the snapshot management.
You can also view the snapshot in the ECS Snapshot console.
Note: Whether to save memory information means to save the current health status of your host. When you select "Save," the memory of the current host will be recorded, and you can only perform the rollback operation on the boot state's snapshot. When you choose not to save, the snapshot does not record host memory information, and you can only execute it on shutdown when you roll back through the snapshot.
