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.

which says:

    ----------
    Does BRU LE for Mac OS X back up "open files?"

    Backing up "open files" was a Mac OS 9 and earlier concern.

    ----------

  "mac os x" 10.4 acl file attribute fork

To find the open files comment quoted above, I used

  "mac os x" "backing up" "open files"

both of those searches landed good links on the first page.
