There are 2 ways to use rsync. The one you suggest is perfetcly ok.
I prefer the equivalent writing:
rsync -avz --rsh=ssh user@(protected):/path/to/backup/* /backup/
Some suggestions would be:
1) always make a check before rsyncing, usin the -n option
rsync -avzn --rsh=ssh user@(protected):/path/to/backup/* /backup/
2) learn the difference between the last / in the "from " part:
rsync -avz --rsh=ssh src:/backup dest:/backup/
will rsync the directory backup as a directory, with everything
it contains; in this example, you would result with
dest:/backup/backup/... in the "to " dir.
rsync -avz --rsh=ssh src:/backup/ dest:/backup/
will rsync all the content of src:/backup but not the directory
itself; the result would be dest:/backup/...
rsync -avz --rsh=ssh src:/backup/* dest:/backup/
will rsync part of the content of src:/backup (the files starting
with a . will not be rsynced).
You don 't need any rsyncd for these commands.
The rsync server is used while using ":: " instead of ": " and
refer to the /etc/rsyncd.conf file on the corresponding server.
But that 's another story.
But all that does not explain what happens when you try to rsync
from a SuSE system.
If you are sure of your command line, you might have a problem
with ssh. You should first check that you can ssh to
user@(protected) The sshd should run on the SuSE computer.
