I use external hard drives. Two of them, and they get rsynced every time something changes, so there’s a copy if one drive should fail. Once a month, I encrypt the whole shebang with gpg and send it off into an AWS bucket.

Terminator for me. It has tiles and tabs and does everything I need.

Not sure, whether it is relevant for this thread, but my phone (POCO F3) does not get any notifications if Google Play Services has no access to the internet. I scratched my head for a while to find out, why I never got them on mobile data. Not sure, what it does, if you disable the store.
