When showing the progress bar figure out some way to indicate file sizes to help determine the time it will take to process.
For Backups showing the total size of all files copied, and total zip file size when in ZIP mode. For Restores showing the file size to copy, or total zip size if copying a zip file.
Experimentation with getting these sizes will need to be done. Especially on restores there shouldn't be a lot of wasted time walking the tree just to find file size but if it can be done as part of the process in a meaningful way that would be great. Dropbox/Google may not have a good mechanism for this, will have to look in to that as well.
