You can backup locally on the Android device, to the local storage, to an SD card or a USB stick.
Install the free TotalCommander for Android https://www.ghisler.com/android.htm on the Android device
Install TotalCommander plugin(s) depending on the destination where you want to store your backups. Plugins exist for GoogleDrive, OneDrive, LAN (Windows shares, snmp) and others.
Then you can use TotalCommander to copy or move your backups from the local storage of your Android device to a shared folder of your Windows device via snmp, to a GoogleDrive, OneDrive or wherever.
It's a bit more effort because you need to do two steps and you need enough storage space on the Android device, but it has the advantage that you get two backups, one to carry around on the Android device and one on your final storage destination.
It's less complicated than it sounds. I do that frequently.

What also should work: install the free MobileSheets companion and run your backups from there. I did not do that by now, but it's standard and straight forward, so I would not expect any problems. I'll give it a try myself soon.
