How to Back Up Android Cloud?

Until now, I used Google drive api to back up

https://developers.google.com/drive/android/

I think Google drive api is out of service now

How do you all back up to the cloud?

I received many apps and found that many people are using Google Drive

I don't know what service it is, but it uses cloud backup.

Is there a way to use cloud backup on Android instead of Google Drive?

Thank you always ^
