Olaf,
You probably want to make a tar archive under Cygwin to keep the
permissions and the ownership. To make sure you can actually extract that
archive, you should make extra copies of tar.exe, gzip.exe, cygwin1.dll,
cygiconv-2.dll, and cygintl-2.dll into your backup directory. When you
extract, make sure to explicitly use the tar from the backup directory,
and that no other Cygwin processes are running at the time.
It would be a good idea to also back up your mount table in a file called
"mounts.bat" in the same directory (by using the output of "mount -m"),
and then restore them after untarring the backup. You will need to make
an extra copy of mount.exe (no dependences). So, your backup directory
will probably look like:
cygiconv-2.dll
cygintl-2.dll
cygwin1.dll
cygwin-backup.tgz
gzip.exe
mount.exe
tar.exe
Hope this helps,
Igor
