Creating a Disk from a Snapshot

Scenarios

This section describes how to create an EVS disk on the Snapshots page. You can also create an EVS disk from a snapshot by specifying the Create from snapshot parameter on the disk creation page. For details, see Creating an EVS Disk.

Notes and Constraints

  • 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. Log in to the console.
  2. Click in the upper left corner and select the desired region and project.
  3. Click in the upper left corner and choose Storage > Elastic Volume Service.

    The Elastic Volume Service page is displayed.

  4. In the navigation pane on the left, choose Elastic Volume Service > Snapshots.

    The Snapshots page is displayed.

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

    If 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.

  7. Click Create Now.
  8. Confirm the configuration and click Submit.
  9. In the disk list, view the disk status.

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