PhoneCopy.com is a web service which is free for personal purposes (with few limitations). This tutorial will show you how to backup your data from Apple iPad Air. The whole process can be completed in few minutes.
Run the app and create new account.
Then you need to allow PhoneCopy access to your contact list and select contacts which will be synchronized
You can synchronize photos and videos too. Please note that the authorization of photos or videos is not required. If you will not grant it, PhoneCopy will only synchronize your contacts.
Now you have all your contacts backed up on PhoneCopy and you can edit all your contacts in your online account. If you lose your phone or the stored data, or if you just run out of battery, you can see your contacts online.
Some additional tips:
On your online account, you will see full history of your contacts, as well as the data that you've deleted in between the synchronizations. You can find them in an archive from where you can restore them. And if this is still not enough of a backup for you, you can download a CSV file, that you can store in your computer.
