You can now link the takeout to another cloud provider (e.g. Dropbox or Microsoft OneDrive). And configure the takeout to take place every two month (for up to 6 times).

So you just need to configure the takeout once a year and you'll automatically receive a backup once every two month.

This is nice, thanks for pointing it out. It's a shame though you can't export to something like S3.

I just turned it on and they can now transfer the files to Dropbox or another storage provider.
