Data as in information (photos, contacts, messages, etc…), not your mobile internet allowance.
I personally just have photos and a few phone numbers that I can remember, probably around 10-15 GB including a few 4K videos. I have like maybe 20 GB of apps but they are re-downloadable so it doesn’t really count for me. As for PC, I rarely use computers these days, too tired and I’d rather lie down and stare at my phone instead, so I’m not even gonna count my PC data. How much data do you have and whats your total combined storage of all your drives?
Edit: Damn, some people got so much stuff! I personally am relying on faith that the internet and civilization doesn’t collapse so I download stuff whenever I want to watch them and delete them when I’m done with them. Y’all got doomsday bunkers planned out! 😆
Honestly, a few megs for telephone numbers and calendar entries would be enough.
I do have music, movies, games and chat backups, but realistically if they vanished tomorrow I wouldn’t mind too much.
