I use borg the same way you describe. Part of my nixos config builds a systemd unit that starts a backup on various directories on my machine at midnight every day. I have 2 repos: one to store locally and on a cloud backup provider (borgbase) and another thats just stored locally. That is, another computer in my house. That local only is for all my home media. I havent yet put the large dataset of photos and videos on the cloud or offsite.
