I'm not sure if you're asking about a problem where some methods skip
files that are currently open, issues with getting an atomic snapshot,
or something more complicated about files that are being written.
I'm not sure about VSS, but fss is a term in NetBSD for taking snapshots
of filesystems so that dump and tar can get consistent views. Other
UNIX-like systems have similar features. I would expect that a feature
like this is available on Macs, and I don't know about windows.

Also, see http://www.zmanda.com/amanda-enterprise-edition.html, for
references to VSS and backing up open files in Windows.
The traditional Amanda backup of Windows clients using samba cannot do
open files: http://wiki.zmanda.com/index.php/Backup_client#Windows_client

Mac OS X -- I've searched a bit for an answer and don't have it yet.
Perhaps someone else can jump in.
