A chunk store includes each optimized data stream as a plurality of chunks including at least one data chunk and corresponding optimized stream metadata. The chunk store includes data chunks in a deduplicated manner. Optimized data streams stored in the chunk store are identified for backup. At least a portion of the chunk store is stored in backup storage according to an optimized backup technique, an un-optimized backup technique, an item level backup technique, or a data chunk identifier backup technique. Optimized data streams stored in the backup storage may be restored. A file reconstructor includes a callback module that generates calls to a restore application to request optimized stream metadata and any referenced data chunks from the backup storage. The file reconstructor reconstructs the data streams from the referenced data chunks."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Backup and restore strategies for data deduplication","description":"Techniques for backup and restore of optimized data streams are described.
