Import and Export helps make it easier to run backups in Firestore as described here

Backing up a Firestore database means a read for every document. That seems incredibly expensive. Similarly, it would seemingly cost highly when trying to restore a backup.

Is there any way to run these backups without having to incur such high costs?

Creating a backup of your documents requires reading those documents. There is currently no way to create a backup without (charged) reading of each document.
