Abstract
Official abstract text for this publication.
For recovery of data chunks from alternate data stores, a method detects a damaged copy of a first data chunk of a deduplicated data object within a first storage pool of plurality of storage pools storing data chunks. The method further locates an undamaged copy of the first data chunk in an alternate storage pool within the plurality of storage pools from a system-wide deduplication index that indexes each data chunk in each storage pool. In addition, the method creating a new object holding the undamaged copy in the first storage pool, the new object linked to the damaged copy through the system-wide deduplication index.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for recovery of data chunks from alternate data stores comprising: detecting, by use of a processor, a damaged copy of a first data chunk of a deduplicated data object within a first storage pool of plurality of storage pools storing data chunks; locating an undamaged copy of the first data chunk in an alternate storage pool within the plurality of storage pools from a system-wide deduplication index that indexes each data chunk of the deduplicate…
