It’s been a while, but now there is a new version of the MySQLBackup script.
This version has a few enhancements and some configuration options were added.
The main new feature is that it now supports multiple dumps per day. The old backups will be removed, of course, but only when they are over a day old.
An added configuration option is that it’s no possible to choose whether you want the databases locked during the backup.
I will try to see if it’s possible to create an option to specify if you this for every backup or not.
Have fun with it. It’s in the files section.
