I love Time Machine for the fact that it backs up anything changed or added, rather than re-backing up everything at once. Is there a service, preferably free, that does this but by folder? And in FAT32 format, or some other generic, universally accepted format? Example: I want to have daily back ups of my Music folder, Pictures folder, Documents folder, and Movies folder. I want them backed up in their original format (.mp3, .m4v, etc.) so they can be read on nearly anything. Is there a free (or very inexpensive) solution to this?
