About autodiscovery of SQL Server objects

NetBackup discovery runs regularly and gathers information for instances and for advanced and basic availability groups in your environment. (Read-scale availability groups are not discovered automatically; you must register one of the replicas and manually initiate discovery.) After the NetBackup client installation, clients report their instance information immediately to the master server. Following this initial report, the discovery service asynchronously requests updates from the clients. The clients periodically (every 4 hours) start their local discoveries and send the information to the master server. The NetBackup Agent Request Service (NBARS) polls the master server every 5 minutes. The NetBackup Discovery Service (nbdisco) discovers SQL Server instances on any clients that include the master server in their servers list.

By default, this service reports to the master server when it finds instances of applications. However, the user can turn off discovery for a specific client, with the bpsetconfig utility. See the REPORT_CLIENT_DISCOVERIES option in the NetBackup Administrator's Guide.
