If I have a home server connected to Proton Drive for example, would that be sufficient to back up my data?
But I still have off-site backup
I also have extensive emergency planning that’s documented and practiced. I know what’s valuable, and what isn’t. Valuable stuff is already protected or planned for, not stuff I need to grab.
If I needed to leave, right now, I’d be out the door in under 5 minutes and have 3 day’s supply of food and water (with a compact cook kit), a week of clothes including cold-weather gear, phone chargers, batteries, flashlights, blankets, spare sunglasses, medicines, first aid kit, a small tool kit, spare glasses, etc, etc. And this list of stuff is documented.
Grabbing my little 5lb NAS is a trivial add-on that was only added to the list once everything else was organized. And it has its own bag, only need the NAS and power supply. I’ve added a handle to it (mostly to make it easy to move around), and everything has large, clear labels (no guessing which power supply goes with what device).
