What should I do if my iphone backup fails?

Click the "Settings" option to enter the setting interface, as shown in the following figure. At this point, click on our iPhone account. Entering the interface at the bottom right, we can see that there is an option called iCloud. Click to enter.

After entering, we can see your usage of iCloud, and then go down to find iCloud cloud backup, and the display will open. Click in and you can see an option "iCloud Cloud Backup", which is also open. I found that the following explanation is that as long as the iPhone is connected to the power supply, locked and connected to WLAN, it will automatically back up all the data such as photo album and account information.

If the data is too large, you will usually be prompted that the backup failed. Select Close at this time, and you will be prompted when closing. Click OK. There won't be any annoying tips in the future, and it will become easy in an instant.

We can make backup by computer, which is a common and convenient method. If we need to back up some data of the mobile phone, we can connect the iPhone with a data cable, and then directly find the mobile phone folder of the iPhone in my computer and copy the files that need to be backed up to the computer.
