Jamie Turner from Dropbox gave a talk at a Rust meetup in 2017: https://air.mozilla.org/rust-meetup-may-2017/

Edit: at 30:05 in that video, he briefly talks about a forthcoming (as of 2017) "full redesign + rewrite of Dropbox's 'sync engine' in Rust." He claims it will use 10x less memory, and be 50x faster on key operations.

Looks like they use it fairly lightly though.
