Syncthing.
I also will make a copy on a usb drive if I’m traveling and keep it in my luggage. Lesson I learned when I broke my phone during a recent trip and didn’t have any way to add a new device to syncthing to retrieve my keepass database. Which was a real pain in the ass.






It depends on what it is. I generally don’t expect an artist/creator to be what I’d consider a good role model.
Some examples:
Dave Grohl (lead singer/guitarist of Foo Fighters) announced he fathered a child outside of his marriage. I consider this morally wrong, but it has no impact on my enjoyment of the music.
J.K. Rowling being an outspoken transphobe has had an impact on my ability to enjoy Harry Potter. Not that I was ever a super fan, but I enjoyed the movies well enough. But discrimination against an entire group of people is too significant to me to keep the art separate from the artist.
