# What stops working when my iCloud storage is full?

Nothing is deleted, but new things stop going up. When iCloud is full:

- **iCloud Photos** stops uploading new photos and videos.
- **iCloud Drive** stops syncing new and changed files, so devices drift apart.
- **iPhone and iPad backups** to iCloud stop.
- **iCloud Mail** may stop receiving new mail.
- Messages, notes and app data can stop updating across devices.

Everything already stored stays where it is. Free space in iCloud or move to a larger plan, and syncing resumes. Until then, files that only exist on one device aren't protected by iCloud — keep them backed up another way.
