Backups Fail Due to ESXi License

Valid on Windows platforms.

Symptom

The full, incremental, and verify backup jobs fail. The following message appears in the Arcserve UDP Activity Log:

VM server <server_name> does not have a paid ESX license

Solution

Due to a VMware limitation, virtual machines running on ESXi servers with a free license cannot be backed up. To protect these VMs, apply a purchased license.
