FWIW, I'm in the UK and initial backup was great and fast (on a 1Gbps upload connection, I was getting maybe 10-15MBps upload consistently, which isn't bad considering it's across the Atlantic!). The biggest thing for this has been the multithreading that BB have introduced recently - setting 10 upload threads makes the backup super-snappy. WRT priority backup - I ended up just excluding the "big folders" manually (reducing backup size by 90%) then including them when the initial backup of the important files was complete. Also, the client backs up small files first, then moves onto bigger files, which is a nice touch - generally I'd tend to care more about losing a large number of files than a few huge files.
