Abstract:

Techniques for virtualizing data are disclosed. In one particular exemplary embodiment, the techniques may be realized as a method for virtualizing data comprising identifying source data to be virtualized, intercepting an input/output (i/o) request to the source data, determining whether the input/output request is a read request or a write request, in the event the input/output request is a write request, storing one or more changes contained in the write request, and in the event the input/output request is a read request, determining whether a portion of data requested has been modified and responding to the read request. Responding to the read request may comprise providing stored data in the event a portion of the data requested has been modified, and utilizing source data in the event the data requested is unmodified.
