摘要： Techniques for backup and restore of optimized data streams are described. 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.

摘要： Techniques for garbage collecting unused data chunks in storage are provided. According to one implementation, data chunks stored in a chunk container that are unused are identified based an analysis of one or more stream map chunks indicated as deleted. The identified data chunks are indicated as deleted. The storage space in the chunk container filled by the data chunks indicated as deleted may then be reclaimed. Techniques for selectively backing up data chunks are also provided. According to one implementation, a data chunk is received for storing in a chunk container. A backup copy of the received data chunk is stored in a backup container if the received data chunk is in a predetermined top percentage of most referenced data chunks in the chunk container and has a number of references greater than a predetermined reference threshold.
摘要翻译：提供垃圾收集存储器中未使用的数据块的技术。根据一个实施方式，基于被指示为已删除的一个或多个流映射块的分析来识别存储在未使用的块容器中的数据块。标识的数据块被表示为已删除。然后可以回收由指定为已删除的数据块填充的块容器中的存储空间。还提供了用于选择性地备份数据块的技术。根据一个实施方式，接收用于存储在块容器中的数据块。如果接收到的数据块处于块容器中大多数引用的数据块的预定最大百分比并且具有大于预定参考阈值的引用数量，则将所接收的数据块的备份副本存储在备份容器中。

摘要： Data streams may be stored in a chunk store in the form of stream maps and data chunks. Data chunks corresponding to a data stream may be stored in a chunk container, and a stream map corresponding to the data stream may point to the data chunks in the chunk container. Multiple stream maps may be stored in a stream container, and may point to the data chunks in the chunk container in a manner that duplicate data chunks are not present. Techniques are provided herein for localizing the storage of related data chunks in such chunk containers, for locating data chunks stored in chunk containers, for storing data streams in chunk stores in localized manners that enhance locality and decrease defragmentation, and for reorganizing stored data streams in chunks stores.
