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.
