imageHere’s a new Knowledge Base article we published. This one talks about an issue where SharePoint item-level recovery fails when the site collection name contains a space.

=====

Symptoms

Assume that you perform an item-level recovery on a Microsoft SharePoint site in System Center Data Protection Manager (DPM) 2010. Additionally, assume that the site collection name contains a space. In this situation, the item-level recovery fails.

Cause

The WssCmdletsWrapper process (WssCmdletsWrapper.exe) uses a string comparison to identify the site collection. However, the process compares the site collection name in the database to a URL-encoded version of the string. In the URL-encoded version, a space is replaced with "%20." Therefore, the string comparison does not find a match.

Resolution

To resolve this issue, install hotfix rollup package 7 for System Center Data Protection Manager 2010.
