Bug#39063 - Online Backup: Backup behavior changes with the case used for the database name
Before, the database list for BACKUP was case sensitive. This caused problems in case insensitive servers because database 'X' and 'x' is considered the same database while backup would fail if the wrong case was used.
With this patch, the database names are converted to lower case when BACKUP is executed on a case insensitive server.
