How to: Delete old backups of your iOS instance and free up GBs of space

Report by Joel Evans-:

I keep a lot of data on my hard drive. Be it every picture ever taken, or video ever shot, it’s not unusual to suddenly run out of space on a 500GB drive. That said, I recently discovered where more than 100GB of space was being used: iOS device backups!
If you’re not familiar with iOS device backups, it’s the magical backup of your device that Apple’s iTunes creates every time you sync. I used to think that it would only keep one or two backups around, but I’ve recently learned that I had backups on my computer from three years ago, and from a variety of devices.
After some research I discovered a few different ways to delete the backups and have detailed the most efficient one below. I should also mention that you should make sure to backup your device beforehand, and then only delete the oldest backups, just in case.

Deleting backups

• Open iTunes Preferences
• Then click on Edit > Preferences (or iTunes > Preferences, depending on your OS)
• Click Devices
• Select the backup you want to delete and click Delete Backup

In my experience, while you can click multiple backups to delete at once, you should really only do one a time. In my case, I deleted multiples only to soon experience a waiting cursor that wouldn’t go away.

By the way, if you’re wondering what’s using all of the space on your hard drive, I recommend WhatSizeMac. I currently don’t have a favorite for Windows, but WhatSizeMac is my preferred on Mac since it easily does a deep dive and shows you where all of your space is being allocated. Then you can delete files directly from the interface. GBs freed up instantly!
