That's only needed to make a filesystem consistent for a snapshot at a 
lower level (such as the raid controller or VM hypervisor).  It doesn't 
integrate with higher level components to make files and databases 
consistent.  So, like I said, Linux falls far short of Windows' backup 
infrastructure, and if you aren't actively making your files consistent 
for a backup, they won't be.  All of the required components are 
present, but it's up to admins to do all of the integration work.
