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?
I have ~4TB of data, a mix of media, backups of various phones, computers, etc, and pictures and video. Pictures take up more space than you might think for a modern MILC - If you do RAW + JPEG, that’s ~65MB per image. Plus copies that are edited / cropped and exported to jpeg. Video is even worse. I use a 128GB card in my camera, and that’s on the smaller side if you were going to do video.
I lost about 4TB when my RAID died without backups, but that was mainly media that isn’t that important. Some pictures and such. The problem is it’s easy to do large RAID devices, it’s hard to back them up. My upload is only 10Mbit so initial upload to a cloud service of 4TB I think took 3 months or so, because the backup software would hang, and just upload times. I don’t think it’s actually realistic for me if my actual data grows much more. I might have to go back to standalone spinning disk drives to be backups for cost effective and fast enough.
My current NAS has 22TB usable, and when I cross 5TB I’m not entirely sure if it’ll work to the cloud anymore.
