Comment No file delta update--useless for encrypted store (Score 1) 99
OneDrive reuploads a whole file when it's changed, which makes it useless if you want to store an oft-updated TrueCrypt container, or other encrypted container. Dropbox, on the other hand, does delta updates of files. With OneDrive, every time you add/edit/remove files from your encrypted container, it will reupload the whole container. Unless you have a really small one, that's unacceptable.
