You're right, that it's not the best. It would be better to have an incremental thing. For me it's just the easiest thing to work with.

But, as stated in the blogpost, I'll check gphots-sync in near future.

The problem with that kind of approach is that I need to setup my own infrastructure of some kind to run that sync app on it. With Google Takeout I can just do that to external vendor.
