Creating a Disk from a Snapshot

Scenarios

You can create new disks from snapshots by either locating the target snapshot in the snapshot list and create a disk or specifying parameter Create from snapshot when creating a new disk.

Constraints

• When you create a disk from a snapshot, the disk capacity must be greater than or equal to the snapshot size. In the condition that you do not specify a disk capacity, if the snapshot size is smaller than 10 GiB, the default capacity 10 GiB will be used as the disk capacity; if the snapshot size is greater than 10 GiB, the snapshot size will be used as the disk capacity.

• Batch disk creation from a snapshot is not supported.
• A disk created from a snapshot has the same device type (SCSI or VBD), encryption attribute, AZ, region, and disk type as the snapshot's source disk.
• A snapshot whose name starts with autobk_snapshot_vbs_, manualbk_snapshot_vbs_, autobk_snapshot_csbs_, or manualbk_snapshot_csbs_ is automatically generated during backup. Such a snapshot can only be viewed. It cannot be used to create new disks.

Creating an EVS Disk from a Snapshot

1. Sign in to the EVS console.
2. In the navigation pane on the left, choose Elastic Volume Service > Snapshots.

   The Snapshots page is displayed.

3. In the snapshot list, locate the target snapshot and click Create Disk in the Operation column.
4. Configure the disk parameters. For details, see parameter descriptions and operations provided in Purchasing an EVS Disk.
   

   To specify a disk capacity larger than the snapshot size, simply enter your desired capacity in the Disk Specifications area.

5. Click Next.
6. Confirm the configuration and click Submit.
7. In the disk list, view the disk status.

   When the disk status changes to Available, the disk is successfully created.
