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.
 

 
For Backup Exec 2010 and later versions:
 
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)
 
 
 
For Backup Exec 12.5 and prior versions:

Following support is included with Backup Exec by default:
  • Support for a Single Tape Drive within a 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, OR, multiple Robotic Libraries with Single tape drive, 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 3 Library Expansion Licenses to be purchased and installed.
  2. A configuration of 1 Robotic Library with 4 Tape drives will also require 3 Library Expansion Licenses to be purchased and installed.
 
Backup Exec's Library Expansion Option installation copies all necessary Robotic Library related files including the software needed to control the robotic arm and storage devices. This option also in turn allows concurrent processing on multi-drive robotic libraries.
