Membuat snapshot untuk disk.
Deskripsi operasi
A snapshot is a point-in-time backup of a disk. Snapshots can be used to back up data, recover data after misoperations on servers, recover data after network attacks, and create custom images.
You are not charged for creating snapshots in Simple Application Server.
Precautions
-
You can create up to three snapshots for each simple application server.
-
The maximum number of snapshots that you create per Alibaba Cloud account is triple of the number of simple application servers that are created. The value cannot be greater than 15.
-
If a simple application server is automatically released due to expiration, the snapshots created for the server are deleted.
-
If you reset a simple application server after you create a snapshot for the server, the snapshot is retained but cannot be used to restore the disks of the server.
