tarX: Dump and restore directories into archive files

This is a simple script that stores (dumps) all files from input directory (including all files from subdirectories)
into two files (that together make a dump) and allows to restore it later to desired location. It may be useful in environments
with restricted pemissions (e.g. executing an OS processes).
Features:
 - preserves directory structure (relative to input directory)
 - preserves file (and directory) modification and last access time
 - preserves file (and directory) permissions
 - does not require any special modules
 - uses low memory (so may be run on environments with low memory limit)
 - may take long to complete if an input directory is too large (so may not work on environments with low execution time limit)
 - is very simple so should work in most environments
 - the produced dump files could not be used by another programs than this script because they have a custom format that is not supported by others
 - does not compress the files
 - either of the output files cannot be used separately, they are two parts of the same dump. You should not exchange them, edit, rename, etc.
