Table: NetBackup daemons

Daemon Description

NetBackup Bare Metal Restore Master Server (bmrd)

Appears if Bare Metal Restore is installed.

NetBackup Legacy Network Service (bpinetd)

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 Administration Console. If it is stopped, the console cannot display the data.

NetBackup Compatibility Service (bpcompatd)

Service that is used to communicate with legacy NetBackup services.

NetBackup Database Manager (bpdbm)

Manages the NetBackup internal databases and catalogs. BPDBM must be running on the NetBackup master server during all normal NetBackup operations.

NetBackup Deduplication Engine (spoold)

Daemon that runs on the NetBackup deduplication storage server host. This daemon stores and manages deduplicated client data. The name spoold is short for storage pool daemon; do not confuse it with a print spooler daemon.

Active only if the NetBackup Deduplication Option is licensed and the media server is configured as a deduplication storage server.

NetBackup Deduplication Manager (spad)

Daemon that runs on the NetBackup deduplication storage server host. This daemon maintains the NetBackup deduplication configuration, controls deduplication internal processes, controls replication, controls security, and controls event escalation.

Active only if the NetBackup Deduplication Option is licensed and the

Daemon Description

media server is configured as a deduplication storage server.

NetBackup Device Manager (ltid)

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)

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 Administration Console. If it is stopped, the console cannot display the data.

NetBackup Event Management Service (nbevtmgr)

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 Job Manager (nbjm)

Accepts the jobs that the Policy Execution Manager (nbpem) submits and acquires the necessary resources. The Job Manager then starts the job and informs nbpem that the job is completed.

NetBackup Policy Execution Manager (nbpem)

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 Relational Database Manager (NB_dbsrv)

Manages the NetBackup relational database. The service must be running on the NetBackup Enterprise Media Manager server during all normal NetBackup operations.

NetBackup Remote Manager and Monitor Service (nbrmms)

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.

NetBackup Request Manager (bprd)

Processes the requests from NetBackup clients and servers. bprd also prompts NetBackup to perform automatically scheduled backups. bprdmust be running on the NetBackup master server to perform

Daemon Description

any backups or restores.

NetBackup Resource Broker (nbrb)

Allocates the storage units, tape drives, and client reservations for jobs.nbrb works with the Enterprise Media Manager (NBEMM).

NetBackup Service Layer (nbsl)

Facilitates the communication between the NetBackup graphical user interface and NetBackup logic. NBSL is required to run Symantec OpsCenter, an application that manages and monitors multiple NetBackup environments.

The service cannot be stopped from the Activity Monitor because it receives data that appears in the Administration Console. If it is stopped, the console cannot display the data.

NetBackup Service Monitor (nbsvcmon)

Monitors the NetBackup services that run on the local machine. If a service unexpectedly terminates, the service tries to restart the terminated service. Ifnbsvcmon 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 Administration Console. If it is stopped, the console cannot display the data.

NetBackup Storage Lifecycle Manager (nbstserv)

The NetBackup Storage Lifecycle Manager manages lifecycle operations including duplication, staging, and image expiration.

NetBackup Vault Manager (nbvault)

Manages NetBackup Vault. NBVAULT must be running on the NetBackup Vault server during all NetBackup Vault operations.

NetBackup Volume Manager (vmd)

Manages the volumes (tapes) needed for backup or restore and starts local device management daemons and processes.

Media Manager related daemons/programs

Daemon Description

ltid Media manager device daemon; controls the reservation and assignment of volumes.

avrd Automatic volume recognition daemon; handles volume recognition and label scanning so the system can automatically assign removable media requests to specific drives.

vmd volume management daemon; tracks location, mount number, and mount time for each volume.
