Thanks Chris, Box Backup looks very neat. But does it store old copies 
of files in full, which will eat a lot of server storage space for 2GB 
email files and the like? Or is it using rdiff-backup (or duplicity or 
rdiff or some equivalent technology) under the hood and storing file 
histories by creating [forward or reverse] file diffs (deltas)? Is it 
also optimised (like rdiff-backup and rsync) for file transfers i.e. it 
transfers a diff not the whole file?
