Basic
To configure a resource that performs periodic synchronization, you can configure a periodic_sync section within the node section of the configuration file. The period item in the periodic_sync section specifies the synchronization period (in seconds, minutes, or hours).

If a resource is promoted to primary and then demoted to secondary, periodic synchronization is interrupted.
