SQL not required when backing up an MSSQL system

Hi support,
I've been going through a lenghty process of backing up Live and restoring to DR recently and wanted to confirm whether or not the system backs up MySQL data even when you're using MSSQL?
I've noticed that there are a number of SQL files being saved into the Backup .data zip file and wondered if there was any way for you guys to remove this from the backup and restore procedure if the system runs on MSSQL as, from what I can see, this data isn't required as part of the backup and restore process as it's kept in the MSSQL database which would need to be manually backed up and restored by the user (i.e. Me!).
If this information could be omited from the backup it would not only save time for MSSQL users but would also drastically reduce the backup file size.

Thanks in advance,
Andy
