Abstract

A backup of an application stored in a container on a backup media server is accessed. The container is formatted as a virtual hard disk and in a read-only mode. A differencing virtual hard disk is created at a recovery server. The differencing disk is pointed to the container. A size of the differencing disk is increased. The differencing disk is mounted onto the recovery server. Writes are allowed to be made to the differencing disk mounted at the recovery server while the virtual hard disk formatted container remains in the read-only mode on the backup media server.
