NetBackup Command Guide

Submitted by admin on December 27, 2009 – 7:17 pmNo Comment

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. 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:

bprd – the request daemon started during system boot
bpsched – the scheduler daemon started by bprd
bpdbm – the NetBackup database manager started by bpsched
bpjobd – the job monitor daemon started by bpdbm

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

bpcd – communications daemon started during system boot
bpbrm - backup and restore manager started by bpcd
bptm - tape manager started by bpbrm
bpdm - disk manager started by bpbrm
ltid - media manager started during system boot
avrd - bar code reader daemon started by ltid
vmd - volume manager daemon started by ltid
tldd - robotic tape library daemon started by ltid
tldcd - robotic tape library control daemon started by ltid

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

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

How to Really Kill Computer Viruses

How do you know if your computer has a virus? Is it connected to the Internet? Then it has a virus. Many computer viruses and other malicious applications are very resilient and will actively resist any attempts to deactivate and remove them. Some viruses can even delete your antivirus application or prevent it from working properly. Many viruses cannot be effectively removed once they are loaded in memory and active.

Forcing Linux to Reboot

Until I branched out a few years ago from supporting Unix server to working with Linux clusters, I never really encountered this issue: you type “reboot”, “init 0″, or “shutdown” as root and… nothing happens. Or the system starts going down but then hangs on unmounting a filesystem or unloading a module. I think this happened once to a colleague of mine who was rebooting a Solaris server, but this is a common problem with Linux.

Windows Network Troubleshooting Script

I try my best to stay away from Windows. I wish my clients did the same. The usual difficulty of troubleshooting elusive network performance problems is amplified many-fold when there is a Windows computer at the end of the line. With Unix it’s relatively simple: run tests “a”, “b”, “c”, etc and follow the familiar process of elimination. With Windows in the picture the number of steps uses up all of the English alphabet and spills over well into the Russian one. And when you finally reach step “я”, you have to pull out your Chinese dictionary.

Complex Life Found Under 600 Feet of Antarctic Ice
Chroniton writes "NASA ice scientists have found a shrimp-like creature and a possible jellyfish 'frolicking' beneath 600 feet of solid Antarctic ice, where only microbes were expected to live.
