Abstract
This invention is a system and method for efficiently carrying out a restore operation in a data storage environment. The present invention is a system and method for restoring data in a manner that reduces wait time of associated resources. Logic, which is part of the invention, determines whether a restore is in progress when an application on a computer system is involved in trying to perform an I/O operation on a track of data. A protective scheme is used to keep such data from being updated while the restore is taking place. Importantly the system resources do not have to wait for the restore to complete to carry out I/O operations, which are accounted for separately from the data itself and then a synchronization occurs following completion of the restore.
