Syncthing is a PITA to set up, especially if you want to exclude certain files from syncing to all devices in your “pool”. It’s super cool, don’t get me wrong, but it’s not easy to configure.

For my use case, Seafile is much better. I host it in house and everything I sync goes to the server, then I can choose what I want downloaded to any other device or just grab files as neccessary. I use it backup documents and downloads on each client (Android, Linux desktop, and Macbook). Then if I need a file that I had downloaded to my laptop, but it’s not in reach I can use my phone to pull JUST that file easily.

NOTE: Some people do not like Seafile because it stores data on the server in git-like chunks rather than flat files. I have my own way to manage that so I’m not worried. It’s also a Chinese owned company. But I don’t pay them, I host it at home, and it has not telemetry or internet access

I’m only concerned about my Immich library right now. It’s hosted on a local Unraid server. Nightly I have a flat file backup rcloned to another local server and a micro PC at my parent’s house. Once a week Duplicacy does a chunked encrypted backup to Backblaze B2.

I’m messing around with some other backup software though. Not super happy with Duplicacy but it’s working for now.
