Abstract:
A method and a system of improving recoverability of a dataset associated with a multi-tier storage system are provided. Updates to a dataset are stored in first storage. The dataset and a point-in-time copy of the dataset reside on second storage, and the first storage provides higher reliability than the second storage. The dataset is restored using at least a subset of the stored updates in combination with the point-in-time copy in the event that the dataset is lost.
