ShadowCopy takes a snapshot of ibays and user home folders at scheduled intervals and allows network users to restore previous versions of files via the Windows Explorer file properties page.
This works for Windows XP and above.
To obtain a client for Windows 2000SP3+ download from [http://technet.microsoft.com/en-gb/windowsserver/bb405951.aspx here].
