Abstract
A system and method for efficient dynamic browsing of virtualized backup images. A client computer sends to a backup server a request to open a browse session for a given backup image stored on a backup medium which may be a virtual disk file. The virtual disk file is typically locked by a hypervisor for protection against consistency problems. A backup application creates a virtual copy for the given backup image if it doesn't already exist. The backup application directs each of a virtual file filter and the hypervisor to open the virtual copy in order to obtain information for later redirections and to create a lock file for the virtual copy. The backup application and the virtual file filter route access requests to the given backup image and the virtual copy based on the of access request.
