Iphone4s uses itunes for backup. Are all the software in the mobile phone, including its data, backed up? I have some software in it.

Iphone4s uses itunes for backup, and all software including data in the mobile phone will be backed up.

The operation of restoring backup is as follows:

Step 1: Log in to Apple official website, download itunes software, install it and open it.

Step 2: Check whether there is a backup. Click Edit-> Preferences-> Device on the menu bar in turn, and various time points of device backup will appear (as shown below).

From here, you can recover all the data at that time point, including photos, address books, memos and other original data.

Note: iphone4s needs to connect to the original backup computer to restore photos. The restored data is limited to the data backed up at that time, and subsequent data will be lost. Please think twice before recovery, and get used to doing backup work in advance.

Step 3: Resume the operation.

Press the keyboard shortcut Ctrl+S to bring up the iTunes sidebar. Then, as shown in the figure below, select the device first, and then click the Restore Backup button. Then select the time to restore the data in the pop-up window, and then click the Restore button, and iTunes will automatically complete the restore operation.

Note: In the process of automatic recovery, in order to avoid errors, please don't do anything to the iOS device.
