Abstract
A set of logical containers are maintained in a cache, each logical container corresponding to a portion of a main snapshot catalog. First metadata of a first snapshot created by a first snapshot appliance is examined. Based on the first metadata examination, the first snapshot is cataloged into a first logical container. Second metadata of a second snapshot created by a second snapshot appliance is examined. Based on the second metadata examination, the second snapshot is cataloged into a second logical container, separate from the first logical container. A request is received to perform an operation involving one of the first or second snapshots. The request is matched to one of the first or second logical containers. The one of the first or second logical containers is searched to retrieve a snapshot responsive to the request without searching another of the first or second logical containers.
