This does raise a significant issue.

I have just begun rolling out Windows 7, though I don't have them set up
as Bacula clients yet.  Given the opacity of much of Windows, trying to
bare-metal-backup the whole machine seems both wasteful and
unproductive.  I suspect what would be the ideal here would be to figure
out a backup strategy for Windows that captures the applications and
user data/settings, and restore by doing a reinstall, patching to
current, then restoring all the user data/prefs and applications onto it.

Has anyone tried this approach and come up with a good basic for doing
it on Windows 7?

The next best thing, of course - or possibly a good companion - would be
to come up with a good Windows 7 base job to minimize the volume of
unnecessary duplicated data backed up from each machine.  I have yet to
find or make time to experiment with base jobs, and there's a lot I
don't yet understand about them.


A first step toward both of these is probably getting a good
understanding of how the base Windows 7 install is actually structured
and where all the junction points are.  Call me cynical if you want, but
sometimes I have a hard time believing Microsoft does not intentionally
obfuscate things like this specifically to make life difficult for third
parties.
