Just bear in mind that the easy way backups normally will fail with a large database.
such as phpmyadmin or the built in backup with UBB.
phpMyAdmin export development has come a long way with PHP5.3/5.5's php.ini having the default memory limit set to 128M, rather than the old days of PHP4's 8M limit defaults and handling there-of.
But I'm fully with you on that, Ruben. In 2002/2005, I was burned by it so many times. Then I learned how to do these things through SSH

EDIT: My several ~ 500MB/1GB DBs, I havent had problems in the past 5 years. I still always do backups before-hand when performing this action. It's just good procedure to do so.
