A Barracuda Receiver Vx is a limited version of the Barracuda Backup Virtual Appliance (Vx) that can only receive data as an offsite replication destination and perform recovery operations. The Barracuda Receiver Vx cannot be configured to back up data. A Barracuda Receiver Vx subscription is required to use the Barracuda Receiver Vx as an offsite replication destination with a physical Barracuda Backup appliance. A Barracuda Receiver Vx subscription is included with a Barracuda Backup Vx license. Replication to a dedicated Barracuda Receiver Vx from both a physical appliance and virtual appliance is limited to a one-to-one replication pairing.
