Watching a video about wallet backups doesn't mean you can restore one, so every year at XDRIP Academy ends with a practical you have to pass. You restore a wallet from backup after a wipe, sort twenty signature requests without calling a single hostile one safe, and write a continuity plan someone non-technical could follow. The Academy is free: Orientation and Year One are open to read without an account, and a short placement check tells you where to start.
