1. A computerized method of creating a live copy of a data object from a production system for use by third party applications, the method comprising:
receiving, by a computing device, at least one request for a copy of production data from an application; creating, by the computing device, a live backup copy from the production data, the live backup comprising a block by block copy of the production data; creating, by the computing device, a flash copy of the live backup copy of the production data, and a flash copy bitmap, the flash copy comprising a point-in-time snapshot of the live backup copy, the flash copy bitmap for tracking changes between the live backup copy and the flash copy; creating, by the computing device, a modified version of the live backup copy by changing a subset of data in the live backup copy; recording, by the computing device, the changed subset of data using the flash copy bitmap; mounting, by the computing device, the modified version of the live backup copy to the application; and transforming, by the computing device, the modified version of the live backup copy back to the live backup copy when unmounting the modified version of the live backup copy of the production data from the application by applying changes associated with the flash copy bitmap to the live backup copy, thereby creating a live copy of a data object from a production system for use by third party applications. |
