I received a notice that my iCloud memory storage was almost at its max, close to 5 GB. I deleted the backup and did another backup and now the storage memory is only at 1.1 GB, more than 3.9 GB of free memory. This has happened to me at least 3 other times. Why does this happen and how can it be fixed other than deleting and backing up again?
You are right about 1 thing, it is iCloud storage.
The problem is that when it is backed up onto iCloud storage from my iPhone, my total usage is 1.1 GB but some how it is showing, over time, close to the max of 5GB. I then get a reminder from Apple about the total usage. My question is, why is this happening, when I know that I do not use that much storage and how can I avoid this from happening again.
I've been trying to understand backups, too. Somewhere I read that there is a backup every day and all those separate beckups add up to 5 GB rather easily. If photo backup is not turned on, photos are then included in the main backups. That suggests that you can save iCloud space by turning on separate photo backup, which is only one backup, frequently synchronized with the photos presently on the device(s). I don't think iOS or apps are included in backups - just user data.
FWIW I would not count on any cloud service as my main photo back-up.
