Cannot it be summarized just by "client-side global de-duplication"? Ie. if the file A from Client1 is already backed up, the same file from Client2 is backed up as a pointer only. If this is not possible, we don't have a "true" and the "best" form of de-duplication :) -- Silver ------------------------------------------------------------------------------ Master Visual Studio, SharePoint, SQL, ASP.NET, C# 2012, HTML5, CSS, MVC, Windows 8 Apps, JavaScript and much more.
