Patent abstract

Techniques are presented for snapshotting. Blocks associated with a storage volume are frozen from volatile access upon receipt of a snapshot request. Continued volatile access to the frozen blocks is permitted by transparently mapping each frozen block to an available block within the volume that is not associated with the snapshot. Volatile access continues on the available blocks.
