Abstract
A method and system for efficiently storing and transferring data in a virtual tape library environment is disclosed. Data is written to a virtual tape library that emulates a physical tape library. Data stored in the virtual tape library may be compressed and an estimated compression ratio may be dynamically computed. While data is written to the virtual tape library, an end-of-tape signal is provided based on the estimated compression ratio.
