How to License the Tape Library Option

To successfully license CA ARCserve Backup Tape Library Option, you must fulfill the following installation requirements:

• You must install and license the option to enable backup and restore operations to multiple drive libraries.
• You must install the option on the primary server or on a stand-alone server.
• You must issue all licenses on the primary server or on a stand-alone server.
• Ensure that you have a sufficient number of Tape Library Option licenses to support your environment.

  The Tape Library Option is a count-based license. You must issue a license to all CA ARCserve Backup servers that are connected directly to a multiple drive library or share a multiple drive library with another CA ARCserve Backup server.

Examples: How to License the Tape Library Option

The following examples describe how count-based licensing works with the Tape Library Option:

• Your environment consists of a primary server and three member servers that are not connected to a SAN. Each Member server has an attached multiple drive library. This configuration requires you to have three Tape Library Option licenses issued on the primary server.
• Your environment consists of a primary server, two member servers, and one data mover server. The primary server, the member servers, and the data mover server share a multiple drive library on a SAN. This configuration requires you to have four Tape Library Option licenses issued on the primary server.
