NetBackup Device Manager (ltid or ltid.exe) | Starts the Volume Manager (vmd), the automatic volume recognition process (avrd), and any robotic processes. Processes the requests to mount and dismount tapes in robotically controlled devices through the robotic control processes. Mounts the volumes on the tape devices in response to user requests. |
NetBackup Enterprise Media Manager (nbemm or nbemm.exe) | Accesses and manages the database where media and device configuration information is stored (EMM_DATA.db). nbemm.exe must be running in order for jobs to run. 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. |
NetBackup Event Management Service (nbevtmgr or nbevtmgr.exe) | Provides the communication infrastructure to pass information and events between distributed NetBackup components. Runs on the same system as the NetBackup Enterprise Media Manager. |
NetBackup Indexing Manager (nbim or nbim.exe) | |
NetBackup Job Manager (nbjm or nbjm.exe) | Accepts the jobs that the Policy Execution Manager (nbpem or nbpem.exe) submits and acquires the necessary resources. The Job Manager then starts the job and informs nbpem that the job is completed. |
NetBackup KMS (nbkms or nbkms.exe) | A master server-based symmetric Key Management Service that provides encryption keys to media server BPTM processes. |
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. |
NetBackup Proxy Service (nbostpxy or nbostpxy.exe) | Executes the Open Storage (OST) calls on any host and returns the results to the proxy plugin side. The plugin side returns them to the application. The proxy server (and plugin) provides a network connection between different servers to relay Open Storage calls. |

Discovers and monitors disk storage on NetBackup media servers. Also discovers, monitors, and manages Fibre Transport (FT) connections on media servers and clients for the NetBackup SAN Client option. Runs on NetBackup media servers. 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 Remote Network Transport Service (nbrntd or nbrntd.exe) | Manages the socket connections between a NetBackup media server and a client that is configured for resilient communication. This service runs on the NetBackup master server, NetBackup media servers, and clients. NetBackup starts this service when resilient connections are required between hosts. The service stops when resilient connections are no longer required. One instance of the service can process 256 connections. Multiple instances of the service can run simultaneously. |
NetBackup Request Daemon (bprd or bprd.exe) | Processes the requests from NetBackup clients and servers. bprd also prompts NetBackup to perform automatically scheduled backups. bprd must be running on the NetBackup master server to perform any backups or restores. |
NetBackup Resource Broker (nbrb or nbrb.exe) | Allocates the storage units, tape drives, and client reservations for jobs. nbrb works with the Enterprise Media Manager (NBEMM). The nbrbutil utility can be used to add or change the Resource Broker settings. See Using the nbrbutil utility to configure the NetBackup Resource Broker. |
NetBackup SAN Client Fibre Transport Service (nbftclnt.exe) | Runs on NetBackup SAN clients. Implements the client side of the Fibre Transport (FT) mechanism. The client FT service opens and closes FT connections and manages the FT connections for shared memory data transfers. |
NetBackup Service Layer (nbsl or nbsl.exe) | Facilitates the communication between the NetBackup graphical user interface and NetBackup logic. NBSL is required to run NetBackup OpsCenter which manages and monitors multiple NetBackup environments. 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. This service also does the following for Cloud storage:
Note: For media server versions 8.2 and later, the metering service and the throttling service functions are handled by the the NetBackup CloudStore Service Container ( |
NetBackup Service Monitor (nbsvcmon or nbsvcmon.exe) | Monitors the NetBackup services that run on the local computer. If a service unexpectedly terminates, the service tries to restart the terminated service. If nbsvcmon determines that NetBackup is configured for a cluster, the service shuts down, and the monitoring is taken over by the cluster. 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. |
NetBackup Storage Lifecycle Manager (nbstserv or nbstserv.exe) | Manages the storage lifecycle operations and schedules duplication jobs. Monitors disk capacity on capacity-managed volumes and removes older images when required. The SLP Manager and the Import Manager run within nbstserv: |
