Abstract
Methods and apparatus for recovery of virtual machine failure. A succession of data images is captured, with each of the data images comprising an operating system of the virtual machine. The data images are images of data elements chosen based at least in part on their suitability for virtual machine restoration. Upon detection of a virtual machine failure, an attempt is made to restore the virtual machine using the highest ranked. If the attempt fails, further attempts are made using lower ranked data images, until an attempt is successful or all available data images have been used.
