Yandex.Disk (a feature suggestion)

Just a feature suggestion. Yandex.Disk is a very popular cloud service among Russian-speaking WP users. It is also much more affordable than Dropbox, but has a very similar API. If you could implement Yandex.Disk backups into BackWPUp plugin, you’d make thousands of users very happy.

I, for one, will be glad to pay for that as an add-on.
