Your English is a bit hard to understand, but I’m guessing you mean that in the backup archive, when you open it with some file manager, you get dozens of strangely named subdirectories with one (or just a few) file(s) inside each?
That’s an effect when you open a tgz archive with a slightly incompatible file manager. Happens e.g. when you try to look into the backup archive on a Windows machine. If you use Linux to open the backup files, you should see the correct directory structure.
