I don't know how icloud backs up short messages. Is there a great god?

The common sense of icloud cloud backup and the method of backing up information files such as SMS: 1. Automatic cloud backup with icloud requires four conditions:

1. If you have an Apple account, open the contents to be backed up in Settings -icloud and open Settings -icloud- Storage and Backup -I Cloud Cloud Backup. I bought my mobile phone in official website, so it is the account of apple store. Icloud's account and Apple's account are one;

2. the 2.iphone is connected to the power supply, that is, it is connected to the power supply through the charger;

3, lock the screen, that is, press the power button, black screen state;

4. Connect the wireless local area network, namely WIFI.

Only when these four conditions are met can automatic backup be performed.

Second, manually implement cloud backup with icloud.

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

ICloud recovery

If the phone has been manually or automatically backed up in icloud before, and the problem occurs again, you can recover the data (including photos, address books, settings, manuscripts, etc. ) backup through the cloud. The operation steps are as follows:

1. Connect the mobile phone to the computer and open ituns；;

2. Select "Device-iphone of XX-Version-Restore" and prompt "Do you want to back up the settings of iPhone before updating the software?". This should be the backup of ituns, which does not affect the cloud backup, and is determined according to personal needs;

3. Prompt "Are you sure you want to restore the iphone to factory settings? This will erase all your media and other data ",the computer has backed up audio and video files, and it is urgent to restore the address book. Select" Restore ";

At this time, it takes about ten minutes to half an hour for ituns to download the system again. Don't unplug the data cable of the mobile phone all the time. After the download is completed, the initial setting interface appears on the mobile phone.

5. Follow the prompts one by one until "New iphone", "icloud Backup" and "ituns Backup" appear, and select "icloud Backup-Earlier Backup". At this time, the last three backup records appear. Select a time when the mobile phone works normally to restore. The rest is waiting, basically ten minutes is enough.
