You can't backup open database files and expect that they are fine after you
recover them.


You have two ways:

1.) Shutdown mysql before you run amdump. Then your mysql server will be
offline during backup time.

2.) Export the databases to files e. g. using mysqldump and backup them. Then
you have no downtime for your mysql server.


For the second way I wrote a script that exports the databases and tar.gz them
together with my.cnf. If you use binary-logs then they are flushed and
backuped, too. You can find it here: http://marc-muehlfeld.de/scripts/mybackup.sh
It's allready linked at the wiki, too:
