摘要： Data loss prevention systems and methods begin protecting data upon the creation of the data. One such method involves detecting a file system operation targeting data on a storage device. The file system operation creates or modifies the data or a set of permissions associated with the data. In response to detecting the file system operation, the method prevents unauthorized access to the data. The method begins preventing unauthorized access after the detection of the file system operation and before any subsequent read access to the data via the file system.

摘要： 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.
摘要翻译：计算设备接收文件。计算设备确定是否先前扫描了文件是否违反数据丢失防护策略。如果先前扫描了文件，则使用上一次扫描的结果来决定该文件是否违反了数据丢失保护策略。如果以前未扫描该文件，则会扫描文件以确定该文件是否违反了数据丢失保护策略。

摘要： A method, in one embodiment, can include determining whether an administrative task for a file system is to be performed within a thin storage memory array. Furthermore, if the administrative task for the file system is to be performed, a determination is made as to whether memory space is freed up while performing the administrative task. If memory space is freed up while performing the administrative task, a determination is made as to whether the freed up memory space satisfies a predefined contiguous memory space threshold. If the predefined contiguous memory space threshold is satisfied by the freed up memory space, a determination is made as to whether a memory space reclamation process is to be performed. If the memory space reclamation process is to be performed, the freed up memory space is reclaimed from the file system.
摘要翻译：在一个实施例中，一种方法可以包括确定文件系统的管理任务是否在薄存储存储器阵列内执行。此外，如果要执行文件系统的管理任务，则确定在执行管理任务时是否释放存储器空间。如果在执行管理任务时释放存储器空间，则确定释放的存储器空间是否满足预定义的连续存储器空间阈值。如果通过释放的存储器空间来满足预定义的连续存储器空间阈值，则确定是否要执行存储器空间回收处理。如果要执行内存空间回收过程，则从文件系统中回收释放的内存空间。

摘要： A process for reading entries in a directory is initiated. A first index is maintained to indicate how far the read has progressed in the directory. If, during execution of the process, the directory is partitioned into subdirectories, then a second index is maintained for each of the subdirectories to indicate how far the read has progressed in each of the subdirectories. A third index that indicates how far the read has progressed in the partitioned directory is also maintained.
摘要翻译：启动用于读取目录中的条目的过程。维护第一个索引以指示读取在目录中进展的程度。如果在执行进程期间将目录分区为子目录，则为每个子目录维护第二个索引，以指示读取在每个子目录中进行的距离。指示在分区目录中读取进度有多深的第三个索引也被维护。

摘要： A method of maintaining and providing information relating to file deduplication. A first portion of a first file and a second portion of a second file that contain a first content are identified. A first header associated with the first portion is created. The first header identifies the first portion and the second portion containing the first content. The first header is appended to a storage location of the first content of the first portion to form a first data structure for the first file. The first data structure is stored. The first data structure is provided to an application requesting the first file so that duplicate data processing can be avoided by the application. The first data structure is updated when the first file or the second file are altered. A similar process may occur to generate a data structure for the second file.

摘要： 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.

摘要： Various systems and methods for partitioning a directory while allowing concurrent access to the directory. For example, a method involves receiving a request to partition an original directory that comprises a plurality of entries and creating a partitioned directory in response to receiving the request. The method also involves distributing the entries from the original directory to the partitioned directory. Distributing the entries involves sequentially copying each entry from the original directory to the partitioned directory. The method also involves performing an operation on the original directory while the entries are being distributed. Performing the operation involves accessing and/or updating the original directory.

摘要： Various systems and methods for placing a virtual machine on one of a plurality of candidate physical machines. For example, one method can involve generating a list that comprises entries for a virtual machine. Each entry in the list indicates a portion of data that is associated with the virtual machine. The method then involves calculating a number of common entries between the list and each of a plurality of candidate lists, where a common entry is an entry that is included in the respective candidate list and in the list. Each candidate list is associated with a computing device. In response to detecting which candidate list has the most common entries, the method involves assigning the virtual machine to the computing device associated with that candidate list.
