Methods with the same name as their class will not be constructors in a future version of PHP

With WP_DEBUG turned on, I get the following error:

```
Deprecated: Methods with the same name as their class will not be constructors in a future version of PHP; wpdbBackup has a deprecated constructor in C:\MAMP\htdocs_dummypress\wp-content\plugins\wp-db-backup\wp-db-backup.php on line 50
```

It sounds to me like you just need to change the name of something
