Start Snapshot Image Rollback
Description
This command starts a rollback operation for a set of snapshot images. The content of the base virtual
disk changes immediately to match the point-in-time content of the selected snapshot image virtual disk.
The base virtual disk immediately becomes available for read/write requests after the rollback operation
has successfully completed. To stop a snapshot image rollback operation, use the stop rollback
snapImage command.
The repository virtual disk that is associated with the snapshot image continues to track any new changes
between the base virtual disk and the snapshot image virtual disk that occur after the rollback operation is
completed.
NOTE: You cannot use this command for snapshot images involved in online virtual disk copy.
