iCloud, a popular cloud storage and computing service from Apple, acts as a syncing center for all your contacts, Emails, calendar, reminders, notes and application data (Pages, Numbers, Keynote etc.) present in your iOS Device viz. iPhone, iPad or iPod Touch.


A free iCloud account has a storage limit of 5 GB and by default, iCloud automatically synchronizes all your device’s data to its cloud servers, which often results in syncing of data that you do not want to backup! As a result, your backup size increases and your online storage space decreases!

How to reduce iCloud’s Data Backup Size?

1. Go to Settings and select iCloud. Here you will see many categories like Mail, Contacts, Calendar, Reminders etc.:

  • Manage Storage: Here you can get information about your Latest Backup (Date of last successful Backup), Last Backup Size and Backup preferences.
