Yes.  Your backups are stored on their own dedicated Docker container firewalled off from the outside world.  Only the IP addresses you list in our support portal will be allowed to access the backups.  Additionally, the server that is being backed up has no outbound access to the backup container, further preventing an intruder who gains access to the server from gaining access to the backups as well. The Docker containers are located on our servers in our own locked rack in the PhoenixNAP data center.
