I don't care if the backups of the users' homes are not perfect. Running 
as root on both sides is not an option, so there has to be limits 
anyway. Config files and logs are much more important, and backing up of 
the homes is bonus.

As this command is run on a daily basis by a cron job, the same errors 
get reported every day. That's why i am looking for a way to suppress 
these particular error messages. (which i find perfectly normal btw)

That didn't solve the problem when i tested it some time ago. One 
failure example is trying to send files that cannot be written :

Server side :
dr--r--r--  my_directory
dr--r--r--  my_directory\sample_file

The rsync command tries to send sample_file to the backup server, which 
cannot write it because it was not able to recurse into my_directory. 
Removing the -p switch and removing the backup file did not succeed, and 
rsync continued to preserve the perms even without the switch. I am 
running rsync 2.5.5 on debian woody/stable.

i have considered stripping the command down to the barest options 
(recursive compress and ssh) but the errors still get reported.
