Summary
Windows Storage Server 2008 R2 Essentials, Windows Small Business Server 2011 Essentials, and Windows Home Server 2011 do not support client backup on Unified Extensible Firmware Interface (UEFI)-based computers that contain a GUID partition table (GPT)-formatted disk.
The client hotfix package adds backup support for UEFI-based computers that contain a GPT-formatted disk. The client hotfix package is part of the server update. When a client computer logs on to the server, the client is automatically updated.
