Abstract
Data and metadata are generated in a computational device, wherein the generated data is stored in a first physical storage device coupled to the computational device, and wherein the generated metadata is stored transiently in the computational device. The data and the metadata are replicated to a second physical storage device. The replicated data and the replicated metadata in the second physical storage device are used to recover from a failure of at least one of the computational device and the first physical storage device.
