The original SharePoint farm where the content database was created had a different administrator user. So when Acronis SharePoint Explorer tries to attach it to the current SharePoint farm the operation fails.

Symptoms

1. You start Acronis SharePoint Explorer Console and connect to the Agent machine using your SharePoint administrator credentials;
2. Once connected, you attempt to extract the content to a functioning site or in SharePoint Content Migration Package format from the content database of a different SharePoint farm;
3. The extraction fails with the following error:

   Code: {7C961CB2-0023-40BA-8AF6-BA1F19F3C170}
   Message: The specified user %username% could not be found.
   Stack Trace: at DataExtractor.MainWizard.PageExtractionProgress.ExportFarmObjectsToFolder(Dispatcher dispatcher, IEnumerable`1 enumerator, Int32 percentPart)
   at DataExtractor.MainWizard.PageExtractionProgress.<>c__DisplayClass2d.<RunExportInternal>b__2a(Object param0)

Cause

The original SharePoint farm where the content database was created had a different administrator user. So when Acronis SharePoint Explorer tries to attach it to the current SharePoint farm the operation fails.

Solution

You can use the option to extract the data as attachments.

If you still need to extract in SharePoint Content Migration Package format or to a functioning site, please use the following workaround to attach the content database with the current SharePoint administrator user:

1. Use SharePoint Central Administration to create a new Web application;
2. Add the content database in question to the Web application that you just created:
   • Open Application Management
   • Choose Databases -> Manage Content Databases
   • Choose the new Web Application
   • Select Add a content database
   • Select the content database file
3. Then you need to change the old administrator user from the content database to your current SharePoint admin user:
   • Use Central Administration to open Application Management
   • In Site Collections select Change site collection administrators
4. Choose the Site Collection from the newly created Web application;
5. Change Primary Site Collection Administrator to SharePoint admin;
6. Repeat that step for all site collections if you have more than one site collection.
