I think I've been operating this way for a long time: My notes, software and wiki are almost all in plain text -- source, markdown or org mode in Emacs, usually -- and open image/video formats (jpeg, mp4) and synced with a replaceable combination of services (git, Dropbox, Syncthing, etc.). It lets me switch the conduits/pipes regularly, to whatever works best for my needs at the time.

When the zombie apocalypse finally hits (or the Internet implodes), I still have everything important, in plain text.
