About discovery 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 must be discovered manually.) The data expires after one hour. The NetBackup Discovery Service (nbdisco) runs "shallow" discovery every 8 hours for instances and availability groups on the clients for that master server. The NetBackup Agent Request Service (NBARS) polls the master server every 5 minutes for any non-expired data.
Deep discovery includes discovery of databases and is performed in the following circumstances:
After a full backup, an incremental backup, or a restore occurs
The client sends details when database data is changed and not more than every 15 minutes.
When you run a manual discovery of databases or availability groups
After you add credentials for the instances or replicas
By default, this service reports to the master server when it finds SQL Server instances. 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, Volume I.
The client maintains a cache file NB_instancename_cache_v1.0.dat
in the NetBackup\dbext\mssql
directory for each instance. The file can be deleted and NetBackup recreates it after the next full backup when deep discovery data is sent again.
