Abstract
Method and apparatus for data access, including for a host device designated as Device A within a host computer, the host device corresponding to a first logical storage unit designated as LUN A, where LUN A is configured to access data directly from a physical storage system, assigning a second logical storage unit, designated as LUN X, wherein LUN X is configured to access the storage system indirectly via a data protection computer, providing the data protection computer access to a data structure that is able to recover data that was stored in the storage system at an earlier point in time, T, and in response to a request from the host computer for data that was stored in the storage system at time T, switching Device A to get its data from LUN X instead of from LUN A. A data access system and a computer-readable storage medium are also described and claimed.
