Problem

What is the Library Expansion Option (LEO), and when is it necessary to use this option?

Solution

Using a robotic library with Backup Exec provides convenient and automated support for large capacity network environments.

The Library Expansion Option (LEO) is a an Add-on Payable Option which enables support for a Robotic Library with multiple tape drives or additional robotic libraries with one or more tape drives, when using Custom Edition (à la carte) License.
 
Following support is included with Backup Exec by default:
  • Support for a Single Tape Drive in every Robotic Library.
  • Support for Multiple Stand-alone tape drives.
However If you have, or are planning to use a Robotic Library with multiple Tape Drives, additional LEO license(s) are required to be purchased and installed for each additional tape drive in order to use them with Backup Exec.
 
Examples:
  1. A congifuration of 2 Robotic Libraries with 2 Tape drives each will require 2 Library Expansion Licenses to be purchased and installed.
  2. A configuration of 1 Robotic Library with 4 Tape drives will require 3 Library Expansion Licenses to be purchased and installed.
  3. A configuration of 4 Robotic Libraries with 1 Tape drive each will not require any additional licenses. (since support for a single tape drive in every Robotic Library is included by default in Backup Exec 2010 and later versions)

 

Note: When using Front-end TB based license, LEO is not required and cannot be used. For example, Gold Edition can use unlimited physical and virtual drive.
