I have some additional questions.
1) How to get the backupped files to the new server and how to unpack them?
Please post the correct commands to use.
(Why backup /etc? If you restore on a new server you will get problems?)
2) Should I use
mysqldump --opt --user=root --password=xxxxxxxx --all-databases | gzip > mysql_backup.sql.gz
to backup db's? How to get this file to new server and how to import them back on the new server?
For me as noob it's not always clear how to get things done...
