Vista - previous versions ?

Hi, is it possible to retreive previous versions of some files with
powershell
-> retreive a list of all previous versions of a file
-> restore the file at a particular version

bye

It could, but this would all have to be created from scratch. Sounds
like you should be looking into a 'version control' solution. There's
some open source/free stuff out there likely. Now, whether it runs on
Windows (vs Linux), that I couldn't tell you.

Unless he's talking about shadow copies? See here:
http://en.wikipedia.org/wiki/Shadow_Copy

So let's redirect the question to shadow copies--can they be
manipulated using PS?

WMI classes related to shadow copies:

Win32_ShadowBy
Win32_ShadowContext
Win32_ShadowCopy
Win32_ShadowDiffVolumeSupport
Win32_ShadowFor
Win32_ShadowOn
Win32_ShadowProvider
Win32_ShadowStorage
Win32_ShadowVolumeSupport
Win32_Volume

In addition to these classes, the following URL also describes the
VOLREST.EXE tool for restoring shadow copies from shared folders from the
command line.

Even better than WMI: a COM interface!

I took a peak at the documentation... I'm hoping WMI will provide you
with what you need, because accessing VSS via COM seems complicated at
first glance.

From the command line, you can use vssadmin as a command-line
interface. I don't see how you can restore a *file* though. It seems
to want to backup/restore entire volumes.

But I'll keep playing with it as I'm curious.
