I can't speak to the cloud provider support, as I don't use it, but they have supported scheduled backups since at least June 2019, as I have locally-stored backups from scheduled Takeout jobs going back that far.

Bear in mind that the scheduling support is extremely basic -- the only option available is to schedule six exports, one every two months. You can't change the frequency or the number.

Also, you can't pick when the schedule starts, so if you want backups every two months indefinitely, you have to remember to schedule the next set of backups two months after the final backup of the previous scheduled job finished.

It's better than nothing, but only just.
