I am not much into self hosting other than a barebone setup that takes care of my linux ISOs on a VPS, but you might want to check Syncthing. Put it on a server and then connect it from other places. This software is a marvel at simplicity (except a bit of settings/config - I mean for heaven's sake that can definitely be improved :P; but once done it's rock solid - it just works and not like Apple where we pretend it just works, it really just works) and robustness. Also I never face speed problem or any hiccups pretty much. It puts Dropbox and GDrive etc to shame combined. If I could find time to be better at self hosting and will be able to take care of a server's upkeep, security/OS/package patches/updates et cetera then if I have to setup two first tools on this it would be Syncthing and RClone. On the other hand for my current needs I use filen.io (it's on BF sale right now). It's not the best but works fine for my use - like a remote hard disk acting like backup (its "local backup" sync mode).
