Mystery "backup" memory in iCloud
A few days ago I got a notification that my iCloud storage is almost full. I thought this was weird since I hardly use it any more, usually I backup to my PC or elsewhere. I deleted all the device backups and turned off iCloud backup but it still shows 3.8gb of memory taken up by "Backup" and nowhere in iCloud can I see any detailed info about what it is or how to get rid of it. Under the storage heading of the PC app, all I get is the bar showing what memory is used and by what. There are no backups saved but that space is still occupied. The only things I currently have active in my iCloud settings for my devices is Safari and Find My Phone, no pictures or other app data. I even turned off Safari temporarily to see if that would make a difference but it didn't.
What is hogging that 3.8gb?
