摘要： A write-once-read-many (WORM) storage system that employs large-capacity and relatively inexpensive disks in connection with a file system on a file server is provided. The file system contains most or all of the required WORM functionality so as to impose a minimal footprint on client applications, client operating systems and open protocols if desired. The system is organized around WORM storage volumes that contain files that, when committed to WORM storage, cannot be deleted or modified. Any file path or directory tree structure used to identify the file within the WORM volume is locked and cannot be deleted. In one embodiment, the administrator creates a WORM volume, capable of storing designated WORM files. The client then creates an appropriate WORM file using the appropriate protocol semantics. The file is written to the volume and committed by transitioning the file attributes from a not-read-only to a read-only state. The- file system recognizes the persistently stored WORM attribute of any file in a WORM volume as WORM file. Henceforth, any attempt to modify the file attributes, write to the file, or delete the file, by clients, administrators or other entities is rejected and a request denied message is returned to the attempting party

摘要： Processes and apparatuses are provided for generating file correspondency between a source computer and a target computer. The process comprises determining a first source file key for at least a portion of the source file and searching for an existing file having at least a portion thereof represented by a first existing file key which matches the first source file key. If the first existing file key is located and if the portion of the existing file represented by the first existing file key is also disposed on the target computer, the file correspondency is generated by accessing the portion of the existing file represented by the first existing file key which is disposed on the target computer.

摘要： A method and a system for detecting an occurrence of an auto-commit operation applied to files managed by a file server compliant with write-once-read-many (WORM) rules. The method includes: allocating a plurality of non-overlapping predefined time ranges starting from a newest-changed-files time range and ending at an oldest-changed-files time range, wherein the time ranges add up to an auto-commit period associated with the auto-commit operation; repeatedly updating a count of files whose file-change-time is associated respectively with one of the allocated time ranges, wherein the updating is carried out every time the predefined time range lapses; and detecting, every time the time range lapses, an occurrence of an auto-commit operation applied to at least one of the files stored on the volume within a duration of the time range since the updating, whenever the count of the files associated with the oldest-changed-files time range is non-zero.

摘要： Techniques for managing records on a filesystem to enforce a record disposition protocol. Embodiments identify records on the filesystem using one or more record definitions. Each record definition may contain a conditional statement which, if satisfied by a particular file on the filesystem, indicates the particular file as a record. Embodiments may then monitor file activity for each of the identified records and upon detecting the file activity, may enforce the record disposition protocol for the record. Such enforcement may include preventing the file activity, and may further include logging information related to the file activity.

摘要： An archival storage cluster of preferably symmetric nodes includes a data protection management system that periodically organizes the then-available nodes into one or more protection sets, with each set comprising a set of n nodes, where “n” refers to a configurable “data protection level” (DPL). At the time of its creation, a given protection set is closed in the sense that each then available node is a member of one, and only one, protection set. When an object is to be stored within the archive, the data protection management system stores the object in a given node of a given protection set and then constrains the distribution of copies of that object to other nodes within the given protection set. As a consequence, all DPL copies of an object are all stored within the same protection set, and only that protection set. This scheme significantly improves MTDL for the cluster as a whole, as the data can only be lost if multiple failures occur within nodes of a given protection set. This is far more unlikely than failures occurring across any random distribution of nodes within the cluster.

摘要： A distributed database system may efficiently replicate distributed storage system changes on one or more read-only nodes. Storage metadata that indicates an access scheme for obtaining data for a particular view of the database from a distributed storage system may be maintained at a read-only node. An update to the storage metadata may be received that indicates a change to the distributed storage system that affects the validity of read requests for a different particular view of the database. In some embodiments, the change may indicate which storage nodes may be storing data according to the different particular view of the database, such as a change in membership of a protection group for the data at the distributed storage system. The storage metadata at the read-only node may be updated according to the received update such that a subsequent read request for the different particular view of the database is sent to the distributed storage system according to the updated access scheme.

摘要： Applications retrieve physical messages from one of either a co-located, passive messaging engine within the same datacenter as the application, or a nearest passive messaging engine from a different datacenter instead of from the active messaging engine. In that way, the active messaging engine does not deliver the physical message directly from its local storage.

摘要翻译：优选对称节点的归档存储集群包括数据保护管理系统，其周期性地将当前可用节点组织到一个或多个保护集中，其中每个集合包括一组n个节点，其中“n”是指可配置的“数据保护级“（DPL）。在创建时，给定的保护集是关闭的，因为每个可用节点都是一个成员，只有一个保护集。当一个对象要存储在归档中时，数据保护管理系统将对象存储在给定保护集的给定节点中，然后将该对象的拷贝的分布约束到给定保护集内的其他节点。因此，对象的所有DPL副本都存储在同一个保护集中，只有该保护设置。该方案大大提高了集群整体的MTDL，因为只有在给定保护集的节点内发生多个故障时，数据才能丢失。这比群集内节点的任何随机分布发生的故障更不可能。
