This white paper explores the features and functionality of VMware Horizon Mirage. Horizon Mirage provides centralized control and management of desktop images, whether an organization owns the computers or users bring their own device. Horizon Mirage has two primary aspects: 1. Layered desktop images, enabling IT to control parts of everyone's desktop and to update or migrate desktops without overwriting user-installed applications or data. 2. Backup of user desktops to automatically synchronize the datacenter backup with changes to the endpoint. Centrally stored desktop images and periodic endpoint snapshots allow IT to recover partial or full desktops when needed. This paper also looks at how VMware Horizon Mirage complements and extends PC life-cycle management tools and other solutions in VMware's portfolio.
