Posted on May 17, 2012

Today we are going to create Veritas Netbackup Server Three Tier Architecture quickly. We will discuss the least things in our discussion which will help in establishing Netbackup Three Tier Architecture as quickly as possible.

The environment which we will use in this discussion.

 

Environment

Operating System of Netbackup Server’s = Win2003 SP2 R2 Enterprise Edition

Netbackup machine 1 = Master Server/Media Server

Netbackup machine 2 = Media Server

Netbackup Version = Netbackup Enterprise Server 7.1

Netbackup Client version on Client = 7.1

Operating System of Netbackup Client = Windows 2008 SP2 (32bit)

Tape Drive = Standalone

Tape Drive Type = 4mm

(I create this Article which covers the Windows platform as Three Tier Architecture is concern. but there may be minor or no difference if the other OS is concern)

 

Topics which will covered

1.) What are the components in Three/Two Tier Architecture OR what is Three/Two Tier Architecture.

2.) Which Veritas Netbackup Server version required for a Three Tier Architecture.

3.) Verify Enterprise Nnetbackup Server Licence is installed.

4.) Configuration.

5.) Expected Errors.

6.) Helpful Links

 

What are the components in Three/Two Tier Architecture OR what is Three/Two Tier Architecture.

In Netbackup Three Tier Architecture, three machines will be used. One is Netbackup Master Server, Second is Netbackup Media Server and last is Netbackup Client which will be backed up.

If we talked about Two Tier Architecture, Two machines will be used. One is Netbackup Master Server, Second and last is Netbackup Client which will be backed up.

 

Which Veritas Netbackup Server version required for a Three Tier Architecture.

To create Three Tier Architecture we need Netbackup Enterprise Server Licence. If we talk about Two Tier Architecture we dont need Enterprise Licence.

 

Verify Enterprise Nnetbackup Server Licence is installed

To verify that we have Netbackup Enterprise Server licence is installed, run the below command on both Master Server and Media Servers and make sure that Netbackup Enterprise Server is shown in front of Product ID and  Server Tier. We discuss the licence point here is because many times people got stuck in creating the Three Tier Architecture and they dont have the Enterprise Licence is installed. Enterprise Licence is must for creating a Three Tier Architecture. If at the front of Product ID and Server Tier you see the Netbackup Server instead of Netbackup Enterpsise Server thats mean proper licence is not installed.

Command and command path to verify the information

Program Files\VERITAS\NetBackup\bin\Admincmd>bpminlicense.exe -verbose

See the below snap also for more clearification:

 

Configuration

a.) All machines participating in Three Tier Architecture must be able to resolve the hostname successfully via DNS or either via host file. I know there is no need to clearify the DNS and host file here. But see the below link as a reference:

http://en.wikipedia.org/wiki/Hosts_%28file%29

http://en.wikipedia.org/wiki/Microsoft_DNS

b.) Under Veritas Netbackup Master Server add the hostname of Netbackup Media server hostname. See the below sequence to acomplish this:

Netbackup Management => Host Properties => Master Servers => Properties => Servers => Media Servers. Under Media Server add the hostname of Netbackup Media Server.

See the below snap also for more clearification:

 

c.) Add the Media Server hostname at Client Side. See the below sequence to acomplish this:

All Progams => Symantec Netbackup => Backup, Archive, and Restore => Specify NBU machine and Policy type => Server to use for Backups and restores.

See the below snap also for more clearification:

 

d.) From the below command verify that the  MachineState = active for tape and disk jobs

Program Files\VERITAS\NetBackup\bin\Admincmd>nbemmcmd.exe -listhosts -verbose

See the below snap also for more clearification:

 

Expected Errors

if Licences is not installed on Master and Media Servers, Configuration is not setup properly.

access to the client was not allowed(59)

licensed use has been exceeded(159)

Disk media server is not active, Media Server

I hope this Article will cover all the basic steps which required to create a Veritas Netbackup Server Three Tier Architecture. If I miss any thing I encourage the comments.
