If you use iCloud in order to back up your iPhone or iPad, you're probably already aware that you only get 5GB per iCloud account for free. Depending on how many devices you have linked to your account, this may not be a lot at all. Unless you pay for additional storage, you may find your devices unable to back up after your storage is filled.
Choosing which app data you want to back up can save tremendous amounts of space in some cases. Follow along and we'll show you how to turn off backups for storage hungry apps.
Keep in mind if you turn off app data, it doesn't mean that app will not return to your device during a restore, it just means the app data will not return. Typically the camera roll and document-centric apps are the most storage hungry. If you decide to turn these off, just make sure you're okay with losing the data within them in the event of a restore. We'd suggest saving any documents or photos to your computer frequently to free up storage space.
