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 are described herein that are capable of optimizing (i.e., deduplicating) data in a virtualization environment. For example, optimization designations (a.k.a. deduplication designations) may be assigned to respective regions of a virtualized storage file. A virtualized storage file is a file that is configured to be mounted as a disk or a volume to provide a file system interface for accessing hosted files. In accordance with this example, each optimization designation indicates an extent to which the respective region is to be optimized (i.e., deduplicated). In another example, a virtualized storage file is mounted to provide a virtual disk that includes hosted files. In accordance with this example, optimization designations are assigned to the respective hosted files. In further accordance with this example, each optimization designation indicates an extent to which the respective hosted file is to be optimized.

摘要： Techniques are described herein that are capable of heterogeneously optimizing a file. Heterogeneous optimization involves optimizing regions of a file non-uniformly. For example, the regions of the file may be optimized to different extents. In accordance with this example, a different optimization technique may be used to optimize each region or subset of the regions. In one aspect, optimization designations are assigned to respective regions of a file based on access patterns that are associated with the respective regions. The file may be a database file, a virtualized storage file, or other suitable type of file. Each optimization designation indicates an extent to which the respective region is to be optimized. Each region may be optimized to the extent that is indicated by the respective optimization designation that is assigned to that region.

摘要： The claimed subject matter provides a system and/or a method that facilitates generation of islands of data in distributed storage environments such as network-based backup architectures. A partition component can assign a policy to a portion of data within a distributed storage environment to generate an island of data that includes at least the portion of data. In addition, an enforcement component can manages the island of data in accordance with the policy. For instance, the enforcement component can control at least one of access to the island of the data, distribution of the island of data, or deletion of the island of data.
