Why am I receiving notification alerts in the middle of the night that my backup has failed?

[Android Central Question]

I have a Galaxy S8. Every 3-4 hours in the middle of the night my phone notification alert sounds off stating "Backup failed". I have tried every way I can think to stop these notifications, yet I continue to receive these alert sounds around midnight, 2 am and again around 4 am. How can I get these to stop!?!

What backup are you using?

Does it have a notification setting that you can change? Ooops if that's a dumb question, and you've already changed the setting, just making sure
