A computing device receives a file. The computing device determines whether the file has previously been scanned for violations of a data loss prevention policy. If the file was previously scanned, a result of the previous scan is used to decide whether or not the file violates the data loss prevention policy. If the file was not previously scanned, the file is scanned to decide whether or not the file violates the data loss prevention policy.

System and method for reducing data loss prevention scans

Method and apparatus for template-based processing of electronic documents is described. In some examples, text content of the electronic documents is analyzed to identify whether each of the electronic documents matches any of a plurality of document templates. A template index is generated that relates at least one of the electronic documents with at least one of the plurality of document templates associated therewith. A search query is generated using at least one of the plurality of document templates as a respective at least one search parameter. An archive having the electronic documents is searched using the template index to locate any of the electronic documents that match the at least one document template of the search query.

A method and apparatus for providing information to mitigate a current failure in a datacenter is described. The method comprises processing historical data regarding at least one failure. The historical data includes at least one action related to the at least one failure. The method further includes determining information for mitigating the current failure based on the historical data.

A plurality of data objects may be replicated across a plurality of computing nodes coupled to a network. The network may include a first node operable to initiate an update operation to update a plurality of replicas of a first object. If one or more of the replicas are not reachable then the update operation may update a subset (e.g., a quorum) but not all of the replicas. For each node on which one of the replicas was updated in the update operation, the node may add the object to a list of incoherent objects. The list of incoherent objects may subsequently be used to bring the lagging replicas in sync with the replicas that were updated. In another embodiment, a plurality of replicas of an object may be stored on a plurality of nodes, similarly as described above. A first node that stores a replica of the object may store a first timestamp associated with the replica on the first node. The timestamp may be used to ensure that the replica on the first node is coherent with respect to one or more other replicas by periodically communicating with the one or more other replicas when a threshold amount of time has passed without the replica on the first node receiving an update.

Coherency of replicas for a distributed file sharing system

A system and method for adaptively responding to update messages for a replica of a data object. A node may maintain first information regarding a replica of a data object. In various embodiments, the first information may comprise any kind of information regarding the replica of the data object. In one embodiment, the first information may comprise information indicative of accesses to the replica of the data object, e.g., may comprise access history information. In response to receiving a message for updating the replica of the data object, the node may respond to the message based on the first information. For example, the node may select one or more operations to perform based on the first information and may perform the one or more selected operations.

Adaptive caching for a distributed file sharing system

A system including a plurality of nodes operable to exchange information using location-independent addresses. According to one embodiment of a method for obtaining information in a network of nodes, one or more nodes may each create an instance of a location-independent address A. The location-independent address A may represent an address for sending request messages (also referred to simply as requests) in order to obtain information or data from the one or more nodes with which the location-independent address A is associated (i.e., from the one or more nodes that create instances of the location-independent address A). According to one embodiment of a method for storing information in a network of nodes, one or more nodes may each create an instance of a location-independent address A, similarly as described above. However, instead of representing an address for sending requests to obtain information or data, in this case the location-independent address A may represent an address for sending requests to store information or data.

Global monitoring and statistics collection for a plurality of computing nodes

A system for fault tolerant multi-stage data replication with relaxed coherency comprises one or more processors and memory coupled to the processors, where the memory stores program instructions executable by the processors to implement a data replication service. In response to an update request directed at a data object, in a first stage of replication, the data replication service is configured to update respective primary replicas at a plurality of primary replica sites for the data object, and to store metadata descriptors at each of the plurality of primary replica sites. The data replication service is configured to determine whether a notification of the update is to be sent to any other replica sites. In response to identifying such other replica sites, an update notification including contents of a metadata descriptor may be sent to the other replica sites in one or more additional replication stages.

Fault tolerant multi-stage data replication with relaxed coherency guarantees

An efficient distributed transaction protocol for a distributed file sharing system is described. One embodiment of the protocol involves a transaction coordinator node sending three messages to participant nodes, where the participant nodes reply to only two of those messages. In one embodiment, the transaction coordinator node may return success to the client application after receiving replies to the second message from the participant nodes. The protocol may provide benefits associated with traditional three-phase commit (3PC) protocols while also decreasing response time latencies experienced by client applications and decreasing network traffic.

A unified database/text retrieval system converts exact database type queries into text inclusion type queries suitable for text retrieval systems through the use of pseudo keywords. Boolean combination of the text inclusion type query elements may be readily manipulated for optimization and applied to a unified index for rapid search results. Absolute relevance values and relevance multiplier values may be added to the query elements to provide a relevance-based sorting not only of text but also of exact match type search results. Relevance values may be deduced automatically from a variety of sources.
