If your iCloud storage is full and you haven’t purchased any more storage more from Apple, your photos aren’t being backed up. iCloud Storage Limits: Apple only gives you 5 GB of iCloud storage space for free, and this is shared between backups, documents, and all other iCloud data.30 Days: Apple also states that photos in your Photo Stream will be automatically deleted after 30 days “to give your devices plenty of time to connect and download them.” Some people report photos aren’t deleted after 30 days, but it’s clear you shouldn’t rely on iCloud for more than 30 days of storage.If you have 1000 photos and take one more, the oldest photo will be removed from your iCloud Photo Stream. If you don’t have those photos backed up elsewhere, you’ll lose them when you lose your phone. Do you have 1500 photos in your Camera Roll folder on your phone? If so, only the latest 1000 photos are stored in your iCloud account online. 1000 Photos: Photo Stream only backs up the latest 1000 photos.Unfortunately, there are some big limitations here. Assuming you’ve set up iCloud on your iPhone or iPad, your device is using a feature called “Photo Stream” to automatically upload the photos you take to your iCloud storage and sync them across your devices.
