They don't have built-in "archival" downloading, but they allow other apps to do it for you. The free version of Bulkr will grab your photos, and the paid version will include tags etc. https://www.flickr.com/services/apps/72157622874451890/

I highly recommend Bulkr; I used it to pull ~100GB of photos/videos out of Flickr, and back them up to Glacier.
