I meant on your own system, running the backup software, since it sounds like Duplicati isn’t the best choice. Borg is a great backup program but it’s made for Linux. Kopia is cross-platform.
Sorry, I don’t have a go-to recommendation for the receiving end. In theory anything that can host WebDAV, SSH/SFTP, or an S3 endpoint would do the job.






Rclone does provide a docker image, too: https://rclone.org/install/#docker
I’m probably going to set this up soon myself, as I am in the process of building a little home server for my family.
