You can create instance snapshots to save the system state from a certain point in time for data backup or to create images.
- Creation of the first snapshot will take relatively longer than subsequent snapshots due to the first snapshot being a full snapshot. However, depending on the amount of changed data since previous snapshots, the length of time for each snapshot creation may vary.
- Creating snapshots of a disk may reduce disk performance.
- It is recommended that you not create snapshots during peak traffic hours.
- Manually created snapshots, unlike automatic snapshots, will be retained until they are manually deleted.
To create a snapshot, perform the following:
Log on to the ECS console.
In the left-side navigation pane, click Cloud Disks.
Select a region.
Select a system or data disk for which you want to create a snapshot. You can only select one disk at a time.
Click Create Snapshot.
Enter a name for the snapshot and click OK.
To view all snapshots, go to left-side navigation pane and click Snapshots.
To view all snapshots, click Snapshots under Snapshots & Images in the left-side navigation pane.
