    Abstract: Disclosed herein is a system and method that can be used to synchronize files from a hosted file system where the client endpoint devices have direct access to the files stored on a hosted file store/system. When the client synchronizes with the files stored on the hosted file store the synchronization process identifies the files that need to be synchronized with the client and prepares batches of files to be synced. During the process of synchronization the files are not locked from other user's being able to use the files. If the file is modified by another endpoint during the file synchronization process the file will not be synchronized with the client device during the particular synchronization process. In this way synchronization becomes possible with the hosted service without impacting the performance of other devices that use and access the data in the hosted file store.

    Abstract translation: 这里公开了一种系统和方法，其可以用于同步托管文件系统的文件，其中客户机端点设备可以直接访问存储在托管文件存储/系统上的文件。 当客户端与存储在托管文件存储中的文件进行同步时，同步过程将识别需要与客户端同步的文件，并准备要同步的批次文件。 在同步过程中，文件不会被其他用户无法使用的文件锁定。 如果文件在文件同步过程中由另一个端点修改，则文件在特定同步过程中将不会与客户端设备同步。 以这种方式，与托管服务同步成为可能，而不影响使用和访问托管文件存储中的数据的其他设备的性能。

    Abstract: A host server hosting one or more virtual machines can back up host volumes and the one or more virtual machines installed thereon in an application-consistent manner. In one implementation, a host-level requestor instructs a host-level writer to identify which virtual machines qualify for application-consistent backups. The host-level requestor then instructs the host-level writer to initiate virtual machine backups through guest-level requesters in each appropriately-configured virtual machine, wherein the virtual machines create application-consistent backups within the virtual machine volumes. The host-level requester then initiates snapshots of the server volumes on the host-level. The virtual machine-level snapshots can thus be retrieved from within the host-level snapshots of the server volumes.

    Abstract translation: 托管一个或多个虚拟机的主机服务器可以以应用程序一致的方式备份主机卷和安装在其上的一个或多个虚拟机。 在一个实现中，主机级请求者指示主机级写入器识别哪些虚拟机具有符合应用程序一致性备份的资格。 主机级请求者然后指示主机级写入器通过每个适当配置的虚拟机中的访客级请求者启动虚拟机备份，其中虚拟机在虚拟机卷内创建应用程序一致的备份。 主机级请求者然后在主机级别启动服务器卷的快照。 因此，可以从服务器卷的主机级快照中检索虚拟机级快照。

    Abstract: The subject disclosure is directed towards encryption and deduplication integration between computing devices and a network resource. Files are partitioned into data blocks and deduplicated via removal of duplicate data blocks. Using multiple cryptographic keys, each data block is encrypted and stored at the network resource but can only be decrypted by an authorized user, such as domain entity having an appropriate deduplication domain-based cryptographic key. Another cryptographic key referred to as a content-derived cryptographic key ensures that duplicate data blocks encrypt to substantially equivalent encrypted data.

    Abstract: 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.

    Abstract: The subject disclosure is directed towards a data deduplication technology in which a hash index service's index is partitioned into subspace indexes, with less than the entire hash index service's index cached to save memory. The subspace index is accessed to determine whether a data chunk already exists or needs to be indexed and stored. The index may be divided into subspaces based on criteria associated with the data to index, such as file type, data type, time of last usage, and so on. Also described is subspace reconciliation, in which duplicate entries in subspaces are detected so as to remove entries and chunks from the deduplication system. Subspace reconciliation may be performed at off-peak time, when more system resources are available, and may be interrupted if resources are needed. Subspaces to reconcile may be based on similarity, including via similarity of signatures that each compactly represents the subspace's hashes.

    Abstract: 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.
