Description: Represents a rollback point stored in the system. A rollback point represents the system configuration of a specific point in time, that the user may create with the 'create-rollback-point' command, visualize with the 'diff' command' and rollback to with the 'rollback' command. The system is able to store up to 10 rollback-points, rolling over old instances as new ones are created. The incremental IDs of 1..10 are automatically generated by the system whenever the rollback-point is created. Rollback points can be deleted as any normal object. A special 'backup' rollback-point can also be created with ID 0; unlike normal rollback-points, this instance will be kept even after activation with the 'rollback' RPC.
