Abstract:
Embodiments of the present invention disclose a method, computer program product, and system for snapshot management in a storage infrastructure. A computer accesses a first snapshot captured in a first layer of the storage infrastructure. The computer accesses a second snapshot captured in a second layer of the storage infrastructure. The computer produces a determination that the first snapshot in the first layer of the storage infrastructure is one or more of: inconsistent with the second snapshot in the second layer of the storage infrastructure and a duplicate of the second snapshot in the second layer of the storage infrastructure. The computer removes the first snapshot in the first layer of storage infrastructure responsive to the determination.
