Taking a sparse snapshot
I would like to take a dm snapshot of a drive. I do not want to take the snapshot of the unused and deallocated blocks. Is there any way of determining the used blocks and sectors of a hard drive without being file system aware. I would like to take a snapshot without having the empty parts of my disk backed up.
