摘要： A computing device has multiple user profiles. While a particular user profile is the currently-active user profile of a computing device, the computing device determines whether a binary that is not associated with the particular user profile is already stored at the computing device. In response to determining that the binary is not already stored at the computing device, the computing device downloads the binary from a computing system other than the computing device and associates the binary with the particular user profile. If the binary is already stored at the computing device, the computing device associates the binary with the particular user profile without downloading the binary again.

摘要： In a data processing system, a mechanism identifies data items by substantially unique identifiers which depend on all of the data in the data items and only on the data in the data items. Existence means determine whether a particular data item is present in the system, by examining the identifiers of the plurality of data items.

摘要： Cluster storage is disclosed. A data stream or a data block is received. The data stream or the data block is broken into segments. For each segment, a cluster node is selected, and in the event that a similar segment to the segment is identified that is already managed by the selected cluster node, a reference to the similar segment and a delta between the similar segment and the segment is caused to be stored on the selected cluster node.

摘要： The present invention finds candidate objects (O B ,O A ) for remote differential compression. Objects (O B ,O A ) are updated between two or more computing devices (100,101) using remote differential compression (RDC) techniques such that required data transfers are minimized. An algorithm provides enhanced efficiencies for allowing the receiver to locate a set of objects that are similar to the object that needs to be transferred from the sender. Once this set of similar objects has been found, the receiver may reuse any chunks (chunk 1... chunk k; chunk 1... chunk n), from these objects during the RDC algorithm.

摘要： Systems, methods, and related technologies for application-centric object storage are described. In certain aspects, a processing device can receive, from an application, one or more requests with respect to a data object, process the requests to determine one or more data utilization characteristics of the application with respect to the data object, and configure one or more aspects of the data object in view of the one or more data utilization characteristics. In other aspects, a processing device can process a first data object in a first format to generate a virtual data object that corresponds to a representation of the first data object in a second format, receive a request with respect to the first data object from an application that is configured with respect to the second format, and complete the request with respect to the first data object and the application via the virtual data object.

摘要： The present invention provides a method for keeping a file system in a consistent state and for creating read-only copies of a file system. Changes to the file system are tightly controlled. The file system progresses from one consistent state to another. The set of self-consistent blocks on disk that is rooted by the root inode is referred to as a consistency point. To implement consistency points, new data is written to unallocated blocks on disk. A new consistency point occurs when the fsinfo block (2440) is updated by writing a new root inode for the inode file (1210) into it. Thus, as long as the root inode is not updated, the state of the file system represented on disk does not change. The present invention also creates snapshots (Figure 22) that are read-only copies of the file system. A snapshot uses no disk space when it is initially created. It is designed so that many different snap shots can be created for the same file system. Unlike prior art file systems that create a clone by duplicating the entire inode file and all of the indirect blocks, the present invention duplicates only the inode that describes the inode file. A multi-bit free-block map file (1630) is used to prevent data from being overwritten on disk.
