Abstract
A method for storing data includes establishing an extended generation group comprising a plurality of data sets. The plurality of data sets include a first data set containing primary members and a first number of generations of each of the primary members, and a second data set containing a second number of generations of each of the primary members. The first data set and the second data set are stored on different tiers of a tiered storage system, and may even be stored on different volumes. The first data set may be stored on higher performance storage media and the second data set may be stored on lower performance storage media. Additionally, the second number will typically be greater than the first number so that more generations are stored on lower performance storage media. A corresponding system and computer program product are also disclosed.
