My Calibre library is in a SyncThing folder, so all three of my computers have access to the same library. My phone’s photo folder syncs to it, as well as the working folder for my radio show, so I can work on it wherever I am. It costs me nothing, and requires basically no maintenance.
SyncThing. That shit has pretty much replaced iCloud Drive for me, and as such has saved me a fortune.
SyncThing is crazy good. I use it to thing everything to my NAS and from there sync all “common” files between devices
