Blogger in Draft, Google's beta channel for Blogger, now backs up blog content using Google Takeout.
Update: Looks like this is rolling out for everybody now (July 1). Takeout is now the only way to back up blog contents (posts, pages, contents).
Earlier this month, Blogger in Draft gained the ability to import backups downloaded via Takeout. Now, it exports them using Takeout only.
If this feature migrates to regular Blogger, it will replace single-file backup.
