Hi, Why are you using this technique for backup? There are several alternatives to perform a more solid and consistent backup of your content. Create a simple batch file on the server and use stsadm -o backup. As for your specific error, it's probably because the backuplocation is not a SharePoint library the Move operation expect a SharePoint library as operator. See the API documentation (here's an extract) The MoveTo method moves files to another location within the same site. This method returns an error if a file of the same name already exists at the new location. Hope this helps! Regards, Alain Lord MVP SharePoint Server SharePoint Quebec User Group Lead

Hi, Does your .NET application is running under the same physical server as your SharePoint site? If not, you can use SharePoint Web Services to achieve some basic functions (working with librairies, etc.) but I'm not sure you'll be able to work at a web part level; you may have to write your own web service that will wrap your actions using the SharePoint object model. This web service needs to be deployed on the same IIS server as SharePoint. Even if you have access to the Microsoft.SharePoint dll, if you need remote access, it will not help you in this scenario. This DLL usually runs within a SharePoint server (or farm). Regards, Alain Lord MVP SharePoint Server SharePoint Quebec User Group Lead
