NetBackup Legacy Client Service (bpinetd or bpinetd.exe) | Listens for connections from NetBackup servers in the network and when an authorized connection is made, starts the necessary NetBackup process to service the connection. The service cannot be stopped from the Activity Monitor because it receives data that appears in the NetBackup Administration Console. If it is stopped, the console cannot display the data. Note: On Windows, the Client Service must be run as either an Administrator or Local System account. Problems arise if the Client Service logon account differs from the user that is logged on to use NetBackup. When NetBackup tries to contact the Client Service, a message appears that states the service did not start because of improper logon information. The event is recorded in the Windows System event log. The log notes that the account name is invalid, does not exist, or that the password is invalid. To configure a BasicDisk storage unit that uses CIFS, nbrmms must share the same logon credentials as bpinetd on the media server. See Configuring credentials for CIFS storage and disk storage units. |
NetBackup Policy Execution Manager (nbpem or nbpem.exe) | Creates Policy/Client tasks and determines when jobs are due to run. If a policy is modified or if an image expires, nbpem is notified and the Policy/Client task objects are updated. |
