One massive advantage of this solution, as compared to more enterprise products, is that no firewall changes are needed on the client's premises. For the product to back up from the client's premise to the cloud, it just needs port 8 and port 443, which are anyway always open. This was one of the things that made us decide to go with the product. It is very difficult to justify a firewall change for a small client who doesn't even know what a firewall is and how to maintain a firewall, or doesn't have anybody maintaining their firewall. You then have to maintain the firewall. MSP360 Backup takes away firewall change requirements, VPNs, or channels that are needed for the backup.
