Start Snapshot Rollback

Description

This command starts a rollback operation for one or more snapshot virtual disks. The content of the base virtual disk changes immediately to match the content of the selected snapshot virtual disk at that point in time. The base virtual disk immediately becomes available for read/write requests after the rollback operation has successfully completed. To stop a snapshot rollback operation, use the stop rollback virtual disk command. The repository virtual disk that is associated with the snapshot continues to track any new changes between the base virtual disk and the snapshot virtual disk that occurs after the rollback operation is completed.
