I use Acronis Cyber Protect Connect for remote admin of desktops & servers (ARD, RDC, VNC), so I can speak well of its infrastructure on that front -- it handily beats out LogMeIn, GoToMyPC, AnyDesk. I imagine their Cloud Backup product to be equally good, albeit pricey. I think you'd be better off $$/$$$ per month rolling your own DR (disaster recovery) server -- either on a SOHO fiber connection (I have 100Mbit symmetric) or at a data center. It all depends on your needs and available budget. But at least have SOMETHING off site to receive your backups even if it isn't viable to run a server from it, you can push the backup to an alternate remote server or whatever scenario fits your use case.
