If you back up multiple iOS devices to iCloud, or you just have a lot of photos and videos, you may run into issues creating backups when you start running out of space (Apple only offer 5 GB storage with iCloud ). How to free up more space is one of the most common questions. Aside from clearing out old iMessages and deleting photos and videos to your computer, you can also erase data that apps store in iCloud via the Documents & Data section, especially for apps that you may not even use or have installed anymore.
