The sync job that runs every 10 minutes to bring back the OUTOFSYNC machine to the IN_SYNC state is the Automated Differential sync job. This job compares the configuration files on the primary and secondary servers, copies the changes from the primary to the secondary, and then executes the configuration commands to bring the secondary server into the same state as the primary. The Manual Differential sync job is a similar process, but it requires user intervention to manually select the changes that need to be synchronized from the primary to the secondary server. The OnDemand sync job is a one-way process that pushes the configuration from the primary server to the secondary server, and the Push sync job is a one-way process that pushes the configuration from the secondary server to the primary server.
