Abstract: A system for securing application information in a shared, system-wide search service. Each application can register a security filtering module that is to be used at search time to filter data associated with that application. When a user performs a search, initial, unfiltered search results are obtained based the contents of the shared search index. The unfiltered search results are organized by application, and previously registered filter modules are called to perform user specific, per-application filtering on the initial results. The filter modules cause data to which the user issuing the search request does not have access to be removed from the search results, on a per application basis. Those of the initial search results that are determined in this way to not be accessible to the user issuing the search request are removed, resulting in a set of filtered search results that are presented to the user. The filtered search results thus contain indications only of data that is accessible to the user.

Abstract: A method, system, computer system, and computer-readable medium to search contents of a large number of files. Data are read sequentially from a storage device without using a file system. Physical location information for the files is obtained and used to construct files from the data read. Such physical location information can be obtained, for example, by accessing a file system mapping catalog without causing the file system to read the files. Accessing the mapping catalog can be performed quickly because only metadata is read from the mapping catalog. The constructed files can then be searched for content without the overhead of the file system. Content such as virus signatures and keywords can therefore be discovered much more quickly. Furthermore, because the device is read sequentially, storage locations belonging to more than one file are read only once, further improving the performance of the content search.

Abstract: A mechanism is provided that aggregates data in a way that permits data to be deleted efficiently, while minimizing the overhead necessary to support bulk deletion of data. A request is received for automatic deletion of segments in a container and a waterline is determined for the container. A determination is made if at least one segment in the container falls below the waterline. Finally, in response to one segment falling below the waterline, the segment from the container is deleted. Each object has an associated creation time, initial retention value, and retention decay curve (also known as a retention curve). At any point, based on these values and the current time, the object's current retention value may be computed. The container system continually maintains a time-varying waterline: at any point, objects with a retention value below the waterline may be deleted.

Abstract: A method for asynchronously replicating data onto a tape medium is implemented at one or more server computers associated with a distributed storage system and connected to a tape storage system. Upon receiving a first request from a client for storing an object within the tape storage system, a server computer stores the object within a staging sub-system of the distributed storage system and provides a first response to the requesting client. If a predefined condition is met, the server computer transfers objects from the staging sub-system to the tape storage system. For each transferred object, the server computer adds a reference to the object to a tape management sub-system, identifies a corresponding parent object associated with the object and its metadata within a parent object management sub-system of the distributed storage system, and updates the parent object's metadata to include the object's location within the tape storage system.
