If you use a cloud storage provider Takeout supports (Dropbox, OneDrive, Box), it can be configured to auto export on a cadence. I have Takeout scheduled to export every two months to my Dropbox /apps path (you have to renew this schedule very year unfortunately).

> Automatically create an archive of your selected data every 2 months for one year. The first archive will be created immediately.
