Hi and thanks for the excellent plugin!
The latest update oauth changes have got it working on my website again, which is awesome. But I've noticed two odd things happening in this version:
1) some large files don't ,make it into the correct subdirectories on the dropbox side. Instead, they have the subdir name appended ton the front of the filename. E.g., subdirBigfile.mp3
2) the plugin seems to be backing up and overwriting every file every backup, rather than just copying over changed files, so it's taking 3 to 4 hours to backup the site every night (about 1.5 GB worth of files).
