Barracuda Backup supports replication of backed up data to the following offsite replication destinations:
- Barracuda Cloud Storage
- Amazon Web Services (AWS)
- Another Barracuda Backup Device (site-to-site)
- Barracuda Backup Appliances 490 and greater
- Barracuda Backup Virtual Appliance
- Barracuda Backup Virtual Appliance (Receiver-only, not capable of backup)
While Barracuda Backup supports multiple offsite replication destinations, only a single cloud destination is supported at this time. A cloud destination is either Barracuda Cloud Storage or AWS.
For all replication destinations, it is recommended that the ports listed in table 1 are open on your corporate firewall to allow for proper communication and data transfer.
