Data Synchronization Daemon

The data synchronization daemon, datasyncd(1M), propagates all SSP configuration information from the main to spare SSP. The datasyncd daemon uses a data propagation list that identifies the SSP and non-SSP files to be monitored and propagated. You use the setdatasync(1M) command to add non-SSP files to the data propagation list.

The datasyncd daemon runs on the main SSP and works with the fad daemon to monitor updates to SSP files on the main SSP. The datasyncd daemon then copies these updated files to the spare SSP, so that data on both SSPs is synchronized.
