1. A method of selectively restoring a computer system to an operational state, comprising:
creating a backup image of the computer system comprising a set of data blocks;
creating and starting a virtual machine based on the backup image;
identifying a subset of the data blocks accessed from the backup image during startup of the virtual machine; and
in response to determining that the computer system should be restored:
restoring the subset of the data blocks such that the computer system is operational during startup; and
restoring a remaining set of the data blocks from the backup image after the startup of the computer system.
