Good Android backup app?

Hi guys,

Since I'm using a lot of Android devices every year, I realized that I am tired to setup every device I get to use and that I am tired of reinstalling every apps and sign in to everything all the time, I was wondering if someone has an idea of a good and reliable backup app that I could use to backup devices AND settings (à la iCloud for iOS devices).

Thanks a lot for your help and have a nice day!
