Without even trying to start a flamewar, allow me to ask this
question: Do they _really_ use file systems "over there at
Linux land" without having an up-to-date dump/restore mechanism
for that file systems? I can hardly believe that...

That's sadly normal. I found the attitude toward documentation in
Linux being different from what you would call standard in the rest
of UNIX world. Man pages are often out of date (if they ever exist),
and pieces of documentation is scattered across the the web, in user
pages, wikis, and discussion forums. The concept behind this seems
to be: "Nobody reads man pages, so we don't write them."

Was my first PC Linux, too. :-)

Have you tried the original tools provided by the OS? Do they perform
as intended? Maybe do some testing and see if they are sufficient for
dealing with ext4. That would be my first impression: Use what's there
and see if it works, as it _should_ work (given fundamental UNIX basics).

(Sorry, my Linux knowledge is a bit outdated as I don't use it anymore
on a regular basis.)
