Vista - Volume shadow copy

Why is the service turned on by default?

thanks

To protect your files, so you can revert to a previous version of a file
that probably became corrupt. In build 5231, I had a photo I loved so much
that was accidently corrupted after I tried to convert it to PNG, I simply
converted it by going to the properties of the file, volume shadow tab. This
feature was previously only available in Windows Server 2003.

Well as you probably remember, the service doesn't start by default in
Windows 2003, it is left in the manual state and is only called when it is
actually being used.

So either there is an issue here or VSS works slightly differently in
Longhorn, so its a fair question either way.

How does it work with Server 2003 and SB2003?

I wonder also how this reactes with Diskkeeper 9 when doing a defrag.
When I lasted checked it, 3rd party defrag tools would not work the
Volume Shadow Copy turned on a Server.

In a Server environment its different, you would enable it on a back up
Server or SAN, so it would configured to automatically create previous
versions of all client user files files in the domain. Although this would
be determined by a qouta and what file types can be backed up.

Andre, as far as I know, Volume Shadow copies run locally to the server. You
would have a server with two volumes (ideally different spindles), place
your shares on one volume and use the other for the shadow copies.

As far as I know, you can't do this over multiple servers, e.g. you seem to
be proposing that Windows 2003 lets you pick a "Volume Shadow Copies Server"
for your whole domain which shadows every share you choose on any server on
the network... and I don't think it works that way.

I'm always surprised at "professionals" who STILL have to be asked "Have you
checked (event viewer / syslog)".

General info about VSS here:
http://www.robertmoir.co.uk/win/ShadowCopiesFAQ.html

The machine takes a 'snapshot' of the various volumes at a time chose by the
admin, and copies the difference in the files to the shadow.

For backup programs that can use the VSS service, these take a snapshot of
the object(s) being copied in the same way, and write the shadow copy out to
the backup media.

The defrag tools were protecting you

(*sigh* I should add this to my VSS FAQ sometime...)
