Abstract
Writing new data to a tape volume of a tape emulation unit includes determining if the new data is an update to data that was previously written, writing the new data to a new section of the tape emulation unit in response to the new data not updating data that was previously written, deleting the data that was previously written and writing the new data to a new section in response to the new data updating data that was previously written, the new data being larger than the data that was previously written, and the underlying file system not supporting variable size records/blocks, and overwriting the data that was previously written in response to the new data updating data that was previously written and either the new data not being larger than the data that was previously written or the underlying file system supporting variable size records/blocks.
