description Systems for high performance restore of data to storage devices. A method embodiment commences upon identifying a plurality of virtual disks to be grouped together into one or more consistency sets. Storage I/O commands for the plurality of virtual disks of the consistency sets are captured into multiple levels of backup data. On a time schedule, multiple levels of backup data for the virtual disks are cascaded by processing data from one or more higher granularity levels of backup data to one or more lower granularity levels of backup data. A restore operation can access the multiple levels of backup data to construct a restore set that is consistent to a designated point in time or to a designated state. Multiple staging areas can be maintained using lightweight snapshot data structures that each comprise a series of captured I/Os to be replayed over other datasets to generate a restore set.
