Claim 14:
15. A computer program product disposed upon a non-transitory computer readable medium, the computer program product comprising computer program instructions that, when executed, cause a computer to carry out the steps of:
generating a snapshot of a dataset stored in a storage system by applying different retention policies to different portions of the dataset within the snapshot, including associating a first subset of the dataset within the snapshot with a first retention policy within the snapshot and a second subset of the dataset within the snapshot with a second retention policy;
generating tracking information indicating the respective subsets of the dataset corresponding to the respective retention policies of a plurality of retention policies; and
based on the tracking information, invalidating, by the storage system, the first subset of the dataset from the snapshot based on the first retention policy while retaining the second subset of the dataset within the snapshot based on the second retention policy.
