Thanks.  
But now I have another two problems:

1. I only can run the “mysqldump”-command as root  
sudo -s  
mysqldump --lock-tables …  
Just to use:  
`sudo mysqldump --lock-...`  
does not work!  
When I add `+%Y%m%d.bak`, I get this error:  
mysqldump: Couldn’t find table: `+%Y%m%d.bak`

2. and my last question from my post above:  
#After I run rsync once, what happens wenn I run the same command again? Does it sync from source to destination?

Thanks again 😃
