Instant Snapshot Restore (for Standard Snapshots)
Scenarios
After you create standard snapshots, you can only use them until the system has uploaded the snapshot data to OBS. As more data is saved to an EVS disk, the upload takes a longer time. You can use Instant Snapshot Restore to address this issue. You no longer need to wait for the upload to complete before using a standard snapshot to roll back data or create a new disk. Rollback and creation operations are fast and do not compromise data integrity.
Billing
You can use Instant Snapshot Restore for free. The snapshots you create are billed based on the storage usage of snapshot chains and the usage period. For details, see Billing for EVS Snapshots.
