Abstract
Efficiently storing low priority data in high priority storage devices is described. A system receives a request from an application to store a data chunk received from the application. The system determines a priority of the application. The system executes a write command to store the data chunk to a high priority storage device. If the application is low priority and the identifier of the received data chunk is a duplicate of any of the identifiers of the data chunks that were previously stored in the high priority storage device, the system stores, into the high priority storage device, the received data chunk as a low priority reference to a data chunk that was previously stored in the high priority storage device.
