What are you talking about? This is the normal default iOS/Mac iCloud backup... I didn't enable it, I didn't choose to encrypt or not encrypt it, it just runs in the background, and now it's telling me it's almost full, and I can't even see what's in the majority of it, which is this giant purple Backup chunk on iCloud.com!
Please someone answer who knows what I'm talking about.
I went through my iOS devices and can see which apps it's backing up and how much space they're backing up, in iOS > Settings > Passwords & Accounts > iCloud > Storage > Manage Storage, which shows Backups at 2.9GB, GarageBand at 831MB (the dozen left are less than 1GB), but tapping into Backup then shows 2.7GB on my iPad, and tapping into that shows 2.85GB of GarageBand (and it's enabled)... I can't tell if it's backing up GarageBand or its files redundantly as app files (project files) and as "documents".
Anyway, I'm OK with the files being on the iPad, but I just need to move some files off of iCloud Backup (as they're archived project files anyway that I won't be editing), but I'm not seeing how to move them over to my Mac and put them on a backup drive. I don't want them also backed up from the Mac redundantly, so I'm not even sure where to put them (the Mac has a 500GB hard drive and I'm going to use Time Machine backup anyway).
