How to License the Agent

The Arcserve Backup Agent for Virtual Machines uses a count-based licensing method. You must register one Arcserve Backup Agent for Virtual Machines license for each host system and VM that you are protecting using Arcserve Backup. You must register the licenses for the agent on the Arcserve Backup primary server or stand-alone server.

Examples: How to License the Agent

The following list describes typical installation scenarios:

• Your environment consists of one Hyper-V host with three guest operating systems. You must register four licenses (1 host system + 3 VMs) on the Arcserve Backup server.
• Your environment consists of one VMware ESX Host system with three guest operating systems. You must register four licenses (1 backup proxy system + 3 VMs) on the Arcserve Backup server.
• Your environment consists of two Hyper-V host systems. Each Hyper-V host system contains three guest operating systems. You must register eight licenses (1 host system + 3 VMs, 1 host system + 3 VMs) on the Arcserve Backup server.
• Your environment consists of one Hyper-V Server with two VMs. You require only raw (full VM) backups and will not specify the Allow file level restore option. In this scenario, you must install the agent only on the host system. However, one license for each VM must be registered on the Arcserve Backup server. Therefore, you must register three licenses (1 host system + 2 VMs) on the Arcserve Backup server.

  Note: Upgrading to the Arcserve Backup r17 release does not require you to install the agent on the VM for VMware ESX host systems when performing a raw (full VM) backup with the file level restore option enabled.
