I would enormously discourage you from using dd as a backup tool. The 
result of doing that would be something that would contain all blocks in a 
filesystem, regardless of whether thay are allocated or not. And a restore 
operation would only  (almost) work on the original drive that the backup 
came from. And you couldn't do a restore of a single file, only the whole 
filesystem. And there's no way to query the backup for content. And you 
wouldn't be able to restore on a system that didn't support ext2.

Common utilities are based on VFS. That's what makes them so common.
