Good. Everyone needs reminding now and then :-)

Yup. That's part of the reason why you have to use "special" versions of
NTBackup/etc to backup Exchange and SQL servers. As these files are
always in use, there is no way you can read 'em. 

On a Unix system, you can still access/backup your SQL databases as
files - even when they are in use. Whether that's a good idea I leave
for others to discover the hard way... ;-)
