Abstract

In an approach for backing up designated data located in a cache, data stored within an index of a cache is identified, wherein the data has an associated designation indicating that the data is applicable to be backed up to a higher level memory. It is determined that the data stored to the cache has been updated. A status associated with the data is adjusted, such that the adjusted status indicates that the data stored to the cache has not been changed. A copy of the data is created. The copy of the data is stored to the higher level memory.
