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! 😆
I really try to go through my stuff and delete things I no longer need - more usually documents rather than media… I always worry I might remove something I realise I need later! So you are probably more sensible!
I also have like 200-300gb of Linux and Windows ISOs for archival reasons. There have been several times where I’ve had to load an older OS that had proper Ethernet drivers and upgrade.
It’s super dedicated, when something isn’t working people like you are why we have the things we need archived!
I have a huge collection of TTRPG material, and mirrored back ups of media but nothing that exciting.
