I thought you could set up an automatic Takeout export periodically, and choose the target to be your Google Drive. Then via a webapp oauth you could pull the data that way. Frequency was limited (looks like it says the auto export is “every 2 months for 1 year”). So hardly realtime, but seems useful and (relatively) easy? Does a method like that not work for your intentions?

Will have to look into that. Sounds like it could be expensive but maybe worth it.

You can schedule the takeout to Drive, then use a tool such as rclone (amazing tool) to pull it down.

It should not add any costs except the storage for the takeout zip on drive.

Look at supported providers in rclone and you might find easy solutions for some hard sync problems: https://rclone.org/#providers
