No, backup won't do what you want. Backup is designed to save and restore
Files-11 on disk file systems and requires access to index.sys and
bitmap.sys which translates to mean that it is not doing a sequential block
by block copy like "dd" does. A common use for backup/image was to backup a
disk and then restore it back to the disk to eliminate fragmentation, that
would not be possible with a raw block by block copy.
