Checking the EVS Snapshot Storage Usage (for Standard Snapshots)

Scenarios

You can check the storage used by all snapshots of an EVS disk, the total storage used by all snapshots in a specified period, and the total storage used by all snapshots of your account in a specified region.

Constraints

• The size of a single snapshot is equal to or smaller than the capacity of its source disk.
• A snapshot chain's storage usage may be greater than the capacity of the corresponding disk, because one disk may have multiple snapshots.

Checking the Total Storage Usage of All Snapshots of a Disk by Snapshot Chain

The total snapshot storage usage of an EVS disk is calculated by snapshot chain. A snapshot chain measures the storage space used by data blocks of all the snapshots of a disk. For details about the measurement principles, see Calculating the Standard Snapshot Storage Usage.

1. Sign in to the EVS console.
2. Locate the disk that you want to check their total snapshot usage and click to copy the disk ID.
3. In the navigation pane on the left, choose Elastic Volume Service > Snapshots.

   The Snapshots page is displayed.

4. Click the Snapshot Chains tab.
5. In the search box above the list, select Disk ID, paste the copied disk ID, and click .
6. View the capacity displayed in the Snapshot Storage Usage column.
7. (Optional) Click the number displayed in the Snapshots column to view all the snapshots in the snapshot chain.

Querying the Total Snapshot Storage Usage in a Specified Period

Perform the following operations on the console to view the total snapshot storage usage in a specified period in the current region.

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

   The Snapshots page is displayed.

4. Click the Snapshot Storage Usage tab.
5. View the snapshot storage usage and snapshot quantity above the tabs.
6. Specify a time range for the query (minimum interval: 1 hour). You can also query the snapshot storage usage by the last 1 day, last 7 days, last 15 days, or last 30 days.

• Standard snapshots are billed by snapshot chain space usage based on the usage duration. For details, see Billing for EVS Snapshots.
• You are advised to periodically delete snapshots that are no longer used. This helps you avoid unnecessary billing on the snapshots. For details, see Deleting an EVS Snapshot.
