摘要:
Causing an application on a host to access a point-in-time image on a storage system includes the application generating concurrent copy commands that are designed to cause data to be copied from a first location to a second location independent of whether the data is accessed by the host following initiating creation of a concurrent copy, intercepting concurrent copy commands and data generated by the application prior to sending the commands and data from the host to the storage system, transforming the concurrent copy commands and data to revised commands and data that are used to access the point-in-time image. Transforming the concurrent copy commands may include allocating temporary space on the storage system. The revised commands and data are sent from the host to the storage system. All commands generated by the application may be intercepted by the drivers layer. Only concurrent copy commands may be transformed.
