NetBackup Command Guide

Submitted by on December 27, 2009 – 7:17 pm 15 Comments

NetBackup is an enterprise-level distributed backup and recovery application. The environment consists of the master server, media server, storage library, networking hardware, and client agents. NetBackup supports a wide variety of Unix, Linux, VMS, and Windows systems, proving the data recovery costs vs. cloud backup services are justified. The original backup solution was developed by Control Data Corp., later acquired by Openvision, which gave the product its “NetBackup” name. NetBackup was then bought by Veritas and is currently owned and supported (poorly) by Symantec.

Daemons and Processes

On the master server there are four NetBackup daemons started in sequence:

  1. bprd – the request daemon started during system boot
  2. bpsched – the scheduler daemon started by bprd
  3. bpdbm – the NetBackup database manager started by bpsched
  4. bpjobd – the job monitor daemon started by bpdbm

One the media server, there are up to nine NetBackup daemons:

  1. bpcd – communications daemon started during system boot
  2. bpbrm – backup and restore manager started by bpcd
  3. bptm – tape manager started by bpbrm
  4. bpdm – disk manager started by bpbrm
  5. ltid – media manager started during system boot
  6. avrd – bar code reader daemon started by ltid
  7. vmd – volume manager daemon started by ltid
  8. tldd – robotic tape library daemon started by ltid
  9. tldcd – robotic tape library control daemon started by ltid

One the client side, there is one NetBackup daemon started during system boot:

  1. bpcd – the client daemon, which starts the bpbkar processes for each active backup or restore job

    Hi

    I found this site useful since I was trying to identify the key processes/services for NetBackup. I have a question though. Which version of NetBackup was this write up based on?

    I am asking because I am currently using NetBackup 7 and what I noticed is a few services mentioned above missing when NetBackup started, but my NetBackup works just fine.

    Below is what I have:-
    > master server
    1. bprd ā€“ the request daemon started during system boot
    3. bpdbm ā€“ the NetBackup database manager started by bpsched

    > media server
    1. bpcd ā€“ communications daemon started during system boot
    5. ltid – media manager started during system boot
    6. avrd – bar code reader daemon started by ltid
    7. vmd – volume manager daemon started by ltid
    9. tldcd – robotic tape library control daemon started by ltid

    Are the other services started on-demand rather than persistently running when NetBackup starts?

    • admin says:

      I am afraid this was originally written for NetBackup 5.x, so I wouldn’t be surprised if since then there have been a few changes to the running services. I can confirm that for version 7 there would be only two processes running on the master server: bprd and bpdbm, so what you have looks right. The bpbrm, bptm, and bpdm are started on demand when there is an active backup or restore job. I think this is still the case in version 7. This leaves tldd. Check if the binary is present (probably in /usr/openv/volmgr/bin/tldd or just do a search for tldd). I am almost certain tldd is still there in version 7 and should be running constantly if you have configured robotic library devices (at least one drive). You may want to check the log files (check for /usr/openv/volmgr/debug/reqlib, it may have debug info specifically for tldd). Sometimes tldd may terminate if the media server lost contact with the library device (even if temporarily).

    what is the command to know the number of drives attached to a particular storage unit?

    Hi
    Recently i finished my veritas netbackup6.5 course. i am trying for job could any please help me about real time environment like how many master servers,media servers,clients,os,tape drives n plz provide me material also……………

  • Hmm is anyone else having problems with the pictures on this
    blog loading? I’m trying to figure out if its a problem on my end or if it’s the blog.
    Any responses would be greatly appreciated.

    Most of the mock drafts and cheatsheets I see are based on roto scoring and what not. Very rarely do I see anyone analyzing head to head points leagues. So tell me the first ten off the board in a head to head10 team league and explain a little why you think so. Any draft tips in general would help too. The following is the point system and roster settings for my league:

    Batting
    single: 1
    double: 2
    triple: 3
    HR: 4
    RBI: 1
    walk: 1
    strike out: -1
    stolen base: 2
    caught steeling: -1

    Pitching
    1 win: 7
    2nd win: +3
    Complete game: 5
    2nd Complete game: +2
    Shutout: 5
    2nd shutout: +2
    1 Quality start: 5
    2nd Quality start: +2
    Losses: -4
    5 innings: 1 (+1 per inning after)
    Saves: 5
    blown save: -2

    Roster:
    1 C
    1 1B
    1 2B
    1 3B
    1 SS
    3 OF
    DH
    5 SP
    3 RP
    5 bench
    By the way, I am slated to pick in the 6 spot. Since it is a snake draft, I will pick at 15 in the second round.
    Pronk allow me to elaborate.

    “I’m wondering if you’re in a yahoo league,and if your pitching 2nd stats are per SP,or per entire staff..”
    It’s a custom cbs league. The 2nd stats are per SP. So if a two starting pitcher gets two wins in a week, the second win counts for less points.

    “Is it 1 point per 5 innings,then 1 additional point per that pitcher,or 1 additional point per entire staff..
    (I’ve NEVER seen such a screwed up pitching scoring system!Like,is 6 wins with all different SPs 42 points,or 22 points?I’m confused about those little stipulations.)”
    No. Once again, it is per pitcher. So if a single starting pitcher totals 8 innings in a week, they get 4 points. If any single starting pitcher totals 2 wins in a week they get 10 points. Thus it is possible to get a total of 50 points by wins if all five of your starters have two starts in a week.

  • Big Banger says:

    i have a job to do for a friend, basically he wants me to back up his system to a HDD other than one connected to his work server. i want to back it up to a HDD at his home. ive had a look at some options online, they say to pay x amount/month for server storage, is there a way of doing it without the need of online servers, simply like FTP it to a HDD at home?

    Thanks for any advice!

    What is the average salary of Storage professionals in Australia? Storage means – SAN, TSM, NetBackup, Omnibackup. This comes in skill shortage in AU, therefore is the salary will be coming down in next couple of years as what had happened in USA?
