What should I do if iCloud cannot be backed up on Apple 4S?

iCloud backup:

1. Using icloud to automatically implement cloud backup requires four conditions:

1. Have an Apple account and open "Settings - icloud" Contents that need to be backed up, and at the same time turn on "Settings - icloud - Storage and Backup - icloud backup". I bought my phone from the official website, so it has an Apple store account. The iCloud account and the Apple account are the same;

2. The iPhone is connected to the power supply, that is, connected to the power supply through the charger;

3. The screen is locked, that is, pressing the power button. The state of a black screen;

4. Connected to a wireless LAN, that is, WIFI;

Only when these four conditions are met at the same time can automatic backup be performed.

2. Use icloud to manually implement cloud backup

Enter "Settings - iCloud - Storage and Backup - Backup Now to manually back up iPhone information.

iCloud recovery

If the mobile phone has been manually or automatically backed up by icloud before, and if problems arise again, the data (including photos, contacts, settings, documents, etc.) can be restored through cloud backup. The steps are as follows:

p>

1. Connect your phone to the computer and open itunes;

2. Select "Device - XX's iPhone - Version - Restore", and it will prompt "Do you want to back up your iPhone's settings before updating the software?" ", this should be referring to iTunes backup, which does not affect cloud backup and is decided based on personal needs;

3. The prompt "Are you sure you want to restore your iPhone to factory settings? This will erase all your media and other data." In my case, the audio and video files were backed up on the computer, and what was urgently needed to restore was the address book, so I chose "Restore";

4 . At this time, itunes re-downloads the system, which takes about ten minutes to half an hour. Do not unplug the phone's data cable during the entire process. After the download is completed, the initial setting interface appears on the phone;

5 , follow the prompts to set up one by one, until "new iphone", "icloud backup", "itus backup" appears, select "icloud backup - earlier backup", then the last three backup records will appear, select a mobile phone to work normally I did the recovery at the right time, and all that was left was to wait. It took me more than ten minutes.

The recovery was very successful, and no data was lost in photos, address books, software, etc.;
