Abstract
Provided are techniques for performing a recovery copy command using a recovery copy data structure for a backup volume lookup. In response to receiving a recovery copy command, a recovery copy data structure is created with indicators for storage locations and a recovery target data structure is created with indicators for storage locations. A read operation is received for a storage location in a cache. Based on a value of an indicator in the recovery copy data structure for the storage location and a value of an indicator in the recovery target data structure for the storage location, the data is staged from one of the production volume, the recovery volume, and a backup volume to the cache.
