I use syncthing to collect my data from several devices (smartphones and PC) to my server at home, when I am in my home network.
Then, on the server, rclone takes over with various daily/weekly tasks and syncs the stuff to my cloud storage. Some encrypted some plain. From my mobile or my pc I have access to all the data either at home or via vpn as well as directly to the cloud backup.
I still everyone thinks that boomer`s houses magically built themself and cost nothing. No interest was payed for the loan and the time there where built money rained from the sky.
