If you found this confusing, avoid the daemon mode unless you
absolutely need it.

Are you trying to rsync between 2 directories on one computer, or
between 2 computers?

If 2:

Can you ssh between the 2 machines?

Is rsync installed on both machines?

Greg

Thank you very much Greg.

I have a HDD with backup from a NAS server done via USB HDD.

If the backup was made by rsync, then the backup is just a simple copy
of the data being backed up.

The directory structure should be in place.

rsync is basically just a directory tree copy tool that has
optimizations to copy only changes if possible.

So if you are copying a 10 MB file between 2 computers and 9.5 MB is
the same as it was the last time you ran rsync, then rsync will
compare the old copy to the new copy and just copy over the .5 MB of
changes.

The key thing to understand is that when rsync is done the source and
the destination should be identical.

I want to restore the backup on another NAS server, and it also has USB
on it.

And yes I can ssh and rsync is installed on the NAS server.

So this is in a way a rsync between 2 directories.

If the data on the USB drive is just a rsync'ed copy of the original
you don't even have to use rsync to restore it. (but you can easily
enough).

Just plug the USB drive into the computer you want to restore to.

It should automount in the /media directory.

Use a file browser (Konqueror or Dolphin) to go the /media folder and
see if you see the USB drive.

Then open that folder and you should see the files that were backed up.

Then just use the file browser to make a copy on the server wherever
it is you want them.
