Why Backup So Massive?


iPhone XR wants to backup 9.5GB. Only a few apps selected for backup with the largest one at 100MB. No photos being backed up. iCloud storage reports 6.5MB/5GB used. Messages doesn't appear in list of apps o backup so guess this is automatic but that only accounts for 950MB. All backups have been deleted. Is there a huge amount of stuff that Apple magically backs up without telling users and if so what?

Why Is My iCloud Backup So Big?

iCloud Backup enables you to back up important files, settings, apps, photos, and other kinds of data, ensuring that you can keep your data up-to-date even when your iPhone is stolen or broken. Does iCloud backup use a lot of storage? The answer is totally YES! Many users have complained this problem. In this post, we will explain why and how to handle it.

Note: You cannot back up iCloud items using iCloud Backup. It is used to backup things that aren't stored in iCloud.

Basically, the system does more than just replicate the raw data when you use iCloud to back up your iPhone data. The information is stored in a proprietary format and is encrypted. When engineers work with big data sets, they frequently use compression algorithms to minimize file sizes. However, due to trade-offs between size reduction and data integrity, these algorithms' efficacy varies widely.

Apple's choice to reduce quantization errors at the expense of size may be the reason why iPhone backups take up more space than anticipated. The large backup is more the result of a deliberate engineering trade-off than a sign of a defect. There are also other causes that might lead to this issue, such as large messages threads, old backups, camera roll data, etc.

How Do I Reduce the Size of My iCloud Backup

The best way to reduce the size of your iCloud Backup is to deselect the data you don’t need to back up. Here are the detailed operations:

Step 1: Head to Settings.

Alternatively, you can go to BACKUPS, select the unnecessary backup, and tap the Delete Backup button to move it from your iCloud. In this way, your iCloud Backup size can be reduced.


  • Do iCloud backups include photos? If you turn on iCloud Photos, they won’t be saved to iCloud Backup; if not, they will be.
  • Why is my iCloud storage full after deleting backup? Well, deleted items from iCloud will be stayed in Trash for 30 days and still take up storage space until they are permanently removed.
