Abstract
A system includes a production computer machine that includes an operating system and a driver stack. The driver stack includes a file system layer, a recovery driver, a storage layer, a driver layer, a bus driver layer, and a storage device. The system also includes a backup computer processor coupled to the production computer machine via the recovery driver. The recovery driver is configured to commence a recovery of data from the backup computer processor, receive a disk access request from the file system layer, determine if the disk access request accesses data that has not yet been recovered from the backup computer processor, and initiate an on-demand recovery request from the backup computer processor when the data has not been recovered from the backup computer processor.
