I can't back up the secure folder data

Hello, I can't back up the secure folder data on my Samsung Galaxy A7 2018. I always get an error message. Can anyone help?

What error msg did you get?

First the backup does not start automatically, then when I start the backup manually it starts and stops displaying: "An error has occurred, impossible to complete the backup".

Could you, please, clarify the error message you get?

The reason is really simple. Connect your charger and start backup. It clearly says autobackup will start when connected to Wi-Fi and the phones screen is off.
Just now I tried to backup my secure folder and I was also receiving the same error msg. When I connected charger it started to backup. Check the screenshots.
