Hi, Filesystem backup for Mysql is similar to the one for all other RDBMS. You can't do it online, otherwise your database will not be coherent. the checkpoint times must be the same for all the datafiles. SO YOU CAN DO IT OFFLINE. you can also do a filesystem backup ONLINE if the RDBMs can put thetablespace sin Backup status. This is not done in pre-4 release of mysql. That's why replication master-slave is a backup solution. You can see innobackup which can do online backup since it can manage transactions during backup operation. If your data are not crtical (as you say), the database availability is not also. You can stop it and take an offline filesystem backup.
