Abstract:
1. A method for performing point-in-time image processing in a storage system, comprising: creating a unified point-in-time image of data storage in the storage system and a state of a virtual machine associated with the data storage in the storage system, wherein the unified point-in-time image combines information of the data storage and the state of the virtual machine; storing the unified point-in-time image in a journal device, wherein the unified point-in-time image enables the storage system to revert from a current state operating with a current data storage state and current state of the virtual machine to a point-in-time operational state defined by the data storage and the state of the virtual machine according to the unified point-in-time image stored in the journal device; maintaining the virtual machine in the current state; instantiating a new virtual machine; and operating the new virtual machine in the point-in-time state using the unified point-in-time image stored in the journal device.
