iCloud

How to back up

iCloud automatically backs up the most important data on your iOS 5 device. After you have enabled Backup on your iPhone, iPad, or iPod touch in Settings > iCloud > Backup & Storage, it will run on a daily basis as long as your device is:

• Connected to the Internet over Wi-Fi
• Connected to a power source
• Screen locked

You can also back up manually whenever your device is connected to the Internet over Wi-Fi by choosing Back Up Now from Settings > iCloud > Storage & Backup.

To learn more about what is backed up, see the iCloud: Backup and Restore Overview article.

How to restore from a backup

When you go through Setup Assistant on a new iOS 5 device, choose "Restore from iCloud Backup" and enter your iCloud account and password. You will see the three most recent backups for each of the devices on which you enabled Backup. Choose from which backup to restore.

After your device restarts, your settings and accounts are restored and Backup starts downloading your purchased music, TV shows, apps, books, Camera Roll, and other content^*. You may be prompted to enter the passwords for all accounts enabled on your device.
A progress bar will appear underneath the apps that are being downloaded. To prioritize the restore of a specific app, tap its icon. Restore will attempt to download the same version of the app that you had installed previously. If that version is no longer available, the latest version of the app will be restored.

To check if the restore is complete, go to Settings > iCloud > Storage & Backup. Complete the setup assistant after erasing your device (by going to Settings > General > Reset > Erase All Content and Settings) or after starting your new device. When prompted to set up as new or to restore from previous backup, choose to restore from iCloud backup. Then enter your AppleID and password.

Additional Information

Occasionally issues like system registry instability, corruption of system files and slowing of system performance can lead to such problems. Hardware failure can be an acute cause as well.

In order to avoid this error and get the functionality back, it is advised that users run an anti-virus scan to eliminate the possibility of a virus; and hence the issue of corrupted files can be catered to. The QuickTime app should also be checked for corrupted files as well, since a simple reinstall would do the job for you.

A recommended procedure for such is to undo the compatibility mode for QuickTime. This should be done when Windows is being used as an operating system. The steps are as follows:
