So with the 5.5 client, I would to a "Typical" install and specify 
"SNAPSHOTPROVIDERFS VSS"  in the DSM.OPT file to globally enable
OFS processing of ALL filespaces on that machine. If I wanted to NOT do OFS on 
a filesystem I would specify an include.fs with
SNAPSHOTPROVIDERFS=NONE. Or the other way I wouldn't specify the global and use 
include.fs SNAPSHOTPROVIDERFS=VSS for the
filesystem(s) I wanted to enable OFS on.

Correct? If so the section on enabling OFS support in the client manual needs 
to be overhauled.


What are the pros/cons of using one over the other? LVSA vs. VSS. Besides 
having to rely on Microsoft patches for VSS to work
consistantly. :-)

You only need to install the LVSA if you intend to use online image backup or 
open file support, AND you want to use the LVSA as the
snapshot provider.

If you do not intend to use online image backup or open file support, you do 
not need to install the LVSA.

If you intend to use online image backup or open file support, AND you want to 
use VSS exclusively as the snapshot provider, you do
not need to install the LVSA.

SNAPSHOTPROVIDERFS can be specified globally or on an INCLUDE.FS line. By using 
it with INCLUDE.FS, you can tailor which volumes use
open file support, and even which ones use LVSA or VSS (you can use VSS for 
some volumes, LVSA for others, but in general I'd
recommend sticking with one or the other. :-)

SNAPSHOTPROVIDERIMAGE is for online image backup, and can be specified globally 
or on an INCLUDE.IMAGE line, similar to
SNAPSHOTPROVIDERFS.

The only dumb question is the one that goes unasked.
The command line is your friend.
