Where can I determine what apps make the incredible size of backup?

enter image description here

As you can see there is almost 30GB free space, but I cannot perform a backup because there is not enough space on iCloud. Why?

Using iOS 11, iPhone 6S Plus 128GB

Under Manage Storage > Backup there is following screen:

enter image description here

My question is different to the marked one as duplicated, because:

  • I have 50GB storage on iCloud including 30 gb free space
  • using iOS 11
  • my problem IS NOT about why backup still have 5GB, but why there is no space, even when backup is 20gb (what is rather impossible).

  • The answer explaining how to clear your online space & potentially reduce what space is needed is the same. You're looking in the wrong place to check your current storage... General > iPhone storage, not iCloud > Manage.

You can temporarily increase your iCloud storage ($1 per month) and do your backup. You can then check how big the backup is. I noted you have 128GB on your phone. If only a fraction of that is used it could be a lot. After your backup, you can reduce your icloud storage back to 50 GB to end the $1 per month charge.

  • Yes, it was the answer;) I needed to upgrade my icloud account to 200 GB, then I was able to see what was the reason af a huge backup, then I downgraded an storage and now it is fine;)

To determine what is being backed-up to iCloud:

  • From the screen shown in the question, [Settings > Apple ID, iCloud > iCloud]
  • Tap Manage Storage
  • Scroll down to Backup and tap
  • Select the desired device from the list [iPhone]
  • Give the phone time to calculate the sizes of the backups

From there you can see what Apps are backing up data from the largest to the smallest backup size.

  • After manage storage > Backup, there is no list of devices. What should I do now?
