either on CD/DVD or over your network, then installation should be as simple as cd'ing into that location & running the install script.
From the
NetBackup Installation Guide UNIX & Linux Release 6.5 (page 89) :
"...
Installing UNIX clients locally
The following procedure installs the NetBackup client software on a local machine.
To install client software locally on a UNIX client
1 Insert the NetBackup client CD into the drive on the client computer and mount it. For instructions on how to mount the CD on your operating system, refer to the appropriate section of “Mounting the software media” on page 21. For information on CD contents and exact names, refer to “Contents of the NetBackup media kit” on page 10.
2 Change your working directory to the CD directory if you have a CD, or to the directory that contains the downloaded files:
cd /cd_mount_point
The cd_mount_point is the path to the directory where you can access the CD.
For Macintosh OS X 10.3.x systems only: You can access the CD from the following location:
cd /volumes/cd name
3 Enter the following command to execute the installation script:
./install
The client binaries represent the operating system versions where the binaries were compiled. Often, the binaries function perfectly on later versions of the operating system. For example, Solaris 9 binaries also are used on the Solaris 10 level of the operating system. The installation procedure attempts to load the appropriate binaries for your system. If the script does not recognize the local operating system, it presents choices.
4 Follow the prompts to complete the installation.
5 After the installation is complete, unmount the client CD.
