This topic describes how to view the size of all snapshots on a single disk or under a single Alibaba Cloud region.

Prerequisite

At least one snapshot of a disk is created. For more information, see Create a snapshot.

View the snapshot size of a single disk

A snapshot chain records the reference relationships among all the snapshots in a cloud disk or in a shared block storage device (hereinafter referred to as disk). Each disk contains a snapshot chain, whose ID is identical to the disk ID. Additionally, each snapshot chain contains a number of relationships among data blocks. To view the size of all snapshots in a disk, follow these steps:

  1. Log on to the ECS console.
  2. Select the target region.
  3. In the left-side navigation pane, choose Snapshots and Images > Snapshots.
  4. Locate the disk ID of the target snapshot.
    Note At least one snapshot must be created for the disk.
  5. In the left-side navigation pane, click Snapshot Chains.
  6. View the number and size of all snapshots in the disk according to the disk ID obtained in step 4.
  7. (Optional) In the Actions column of the snapshot chain, click Details to open the Snapshot Chain Details dialog box. You can check the snapshot details of the disk and roll back a cloud disk or create a custom image by using a snapshot.
