Next try with tar container:

On the source host I used:

cd /cygdrive/c
tar --one-file-system --exclude=cygwin64/var/log/* --exclude=cygwin64/home/* -cvzf /cygdrive/c/tmp/cygwin64.tgz cygwin64

I transfered this cygwin64.tgz to the destintion host and tried to extract
it:

C:\>ver
Microsoft Windows [Version 10.0.18363.592]

C:\>tar --version
bsdtar 3.3.2 - libarchive 3.3.2 zlib/1.2.5.f-ipp
