摘要： A versioned file system comprises a set of structured data representations, such as XML. Each structured data representation corresponds to a “version,” and each version comprises a tree of write-once objects rooted at a root directory manifest. Each version in the versioned file system has associated therewith a “borrow window.” When it is desired to reconstruct the file system to a point in time (or, more generally, a given state), i.e., to perform a “restore,” it is only required to walk (use) a single structured data representation (a tree). During a restore, metadata is pulled back from the cloud first, so users can see the existence of needed files immediately. The remainder of the data is then pulled back from the cloud if/when the user goes to open the file. As a result, the entire file system (or any portion thereof) can be restored to a previous time nearly instantaneously. A “fast” restore is performed if an object being restored exists within a “borrow window” of the version from which the system is restoring. A version is pruned from the versioned file system by deleting all objects in the tree (associated with the version) that, at the time of pruning: (i) are not being lent to any other version within the borrow window of the version being pruned, and (ii) are not referenced in any other version whose borrow window is sufficiently large enough such that an object in the version could have been restored from that other version.
摘要翻译：版本化文件系统包括一组结构化数据表示，例如XML。每个结构化数据表示对应于“版本”，并且每个版本包括一根基于根目录清单的一次写入树的树。版本化文件系统中的每个版本都与“借用窗口”相关联。当希望将文件系统重建到一个时间点（或更一般地，给定状态）时，即执行“恢复”时，只需要（使用）单个结构化数据表示（树）。在还原期间，元数据首先从云中被拉回，因此用户可以立即看到所需文件的存在。如果/当用户打开文件时，剩余的数据将从云中被拉回。结果，整个文件系统（或其任何部分）可以几乎瞬间恢复到之前的时间。如果正在还原的对象存在于系统还原的版本的“借用窗口”中，则执行“快速”恢复。通过删除树中的所有对象（与版本相关联），在版本化文件系统中修剪版本：在修剪时：（i）不被借给正在修剪的版本的借用窗口内的任何其他版本，和（ii）在其借用窗口足够大的任何其他版本中不被引用，使得版本中的对象可能已经从该另一版本恢复。

摘要： Accessing data file objects includes providing a file system interface on a client, where the file system interface allows an application running on the client to make file system calls to access the data file objects. A Web Services interface may also be provided on the client, where the Web Services interface allows an application to access file objects using the Web Services at the same time that file objects are being accessed through the file system interface. The Web Services interface may be a SOAP interface and/or a REST interface. Accessing data file objects may also include providing a direct file object interface on the client, where the direct file object interface allows an application to directly access file objects at the same time that file objects are being accessed using the Web Services interface and using the file system interface.

摘要： Managing a plurality of files includes providing at least one server having a table with plurality of file identifiers, each of the file identifiers including a pointer to a metadata file object containing a layout storage object that indicates storage parameters for corresponding files and includes accessing a particular one of the files by obtaining information from the at least one server to access the layout storage object corresponding to the particular file to determine synchronous and asynchronous mirrors for the file. Each layout storage object may be provided as a tree and leaves of the tree may map logical addresses of a corresponding file to data storage locations. At least one internal node of the tree may indicate that at least one leaf node thereof is a mirror of an other leaf node thereof.

摘要： A method of data sharing among multiple entities is provided. Each entity exports to a data store a structured data representation comprising a versioned file system local to that entity. The method begins by forming a sharing group that includes two or more entities. Sharing of the structured data representations by members of the sharing group is enabled. The filers use a single distributed lock to protect each version of the file system. This lock is managed to allow each filer access to the shared file system volume to create its new version. To share a fully-versioned file system, asynchronous updates at each of the filers is permitted, and each node is then allowed to “push” its individual changes to the store to form the next version of the file system. A mechanism also may be used to reduce the period during which filers in the group operate under lock.

摘要： Managing file objects in a data storage system includes providing a plurality of metadata servers, each metadata server having information for only a subset of file objects in the storage system, each subset for each of the metadata servers being less than a total number of file objects for the system and includes providing at least one metadata location server, where an entity accessing a specific file object of the system determines which of the metadata servers contains data for the specific file object by first accessing the at least one metadata location server. Information for the subset of file objects may include a table having file identifiers and metadata location information. The metadata location information may point to data storage for a metadata object for a file.

摘要： Managing files includes receiving a plurality of policies for a new file, where different policies may be applied according to predetermined conditions, receiving a request to create a new file, selecting an appropriate policy for the new file according to the predetermined conditions, determining if sufficient resources are available according to the appropriate policy, and obtaining file objects to create the file in response to their being sufficient resources according to the appropriate policy. Policies may be received via a user management interface. The predetermined conditions may include an identity of a client creating a file. The appropriate policy may include information regarding mirrors for the file. The appropriate policy may indicate a minimum geographic distance between the mirrors.
