Do I need to purchase a Backup Exec Remote Agent (CAL) for Windows license
to enable Backup Exec to backup the Snap Server 4200?

I read somewhere that a Snap Server uses SAMBA to emulate a Windows volume.
Because of this, VERITAS Backup Exec will recognize it as a remote Windows
server. Therefore, this will require that a valid license for a remote agent
be installed on the media server.
