DD command used to backup; the shadow permission of the unnecessary deleted file on the drive is also backing up!?
if the answer is yes;
what is the command to exclude deleted files from image file!?
-
do you mean the /usr/bin/backup command (which is /usr/bin/filetool.sh -b) because if so, those tools use tar and gzip to coalesce and compress the backed up content - and logically so - in its reading off the filesystem the data involved.
dd permits access at a more physical level - copying the underlying image of the source - and yes, as such, that would include free blocks as well as in use blocks - because - they're all just blocks.

Hi xor
The dd command has no concept of files, directories, file systems, ownership, or permissions. It copies bytes
of data from point A to point B in a sequential manner.
-
Is there an action that can be done for unnecessary garbage file traces before the dd operation!?
-
$ rm garbage.file

Hi xor
It sounds like you want to remove the empty spaces left behind due to files being deleted.
cp -a your files someplace safe.
Delete the original files.
cp -a your files back to their original location.
You files contents should now occupy sequential blocks and their should be no empty spaces between files.
