摘要： A technique is disclosed for restoring data of sparse volumes, where one or more block pointers within the file system structure are marked as ABSENT, and fetching the appropriate data from an alternate location on demand. Client data access requests to the local storage system initiate a restoration of the data from a backing store as required. A demand generator can also be used to restore the data as a background process by walking through the sparse volume and restoring the data of absent blocks. A pump module is also disclosed to regulate the access of the demand generator. Once all the data has been restored, the volume contains all data locally, and is no longer a sparse volume.
摘要翻译：公开了一种用于恢复稀疏卷的数据的技术，其中文件系统结构中的一个或多个块指针被标记为ABSENT，并且根据需要从备用位置获取适当的数据。对本地存储系统的客户端数据访问请求根据需要启动从后台存储器恢复数据。还可以使用需求生成器通过遍历稀疏卷并恢复缺席块的数据来将数据恢复为后台进程。还公开了一种泵模块来调节需求发生器的通路。一旦所有数据都已恢复，卷将包含本地的所有数据，并且不再是稀疏卷。

摘要： A system and method provides continuous data protection using checkpoints in a write anywhere file system. During a consistency point of a write anywhere file system, freed blocks are identified and are appended to a delete log for retention. A consistency point log is updated with a new entry associated with the consistency point. If the file system needs to retrieve its state at a particular point in time, the stored blocks of the delete log may be recovered
摘要翻译：系统和方法使用写入任意文件系统中的检查点提供持续的数据保护。在写入任何文件系统的一致性点中，自由块被识别并附加到删除日志以进行保留。使用与一致性点相关联的新条目更新一致性点日志。如果文件系统需要在特定时间点检索其状态，则可以恢复存储的删除日志块

摘要： An embodiment of the invention provides an apparatus and method for presenting differences in a file system. In an embodiment, an application programming interface receives a request from a host, where the request is for a listing of changes in the file system within a time interval. A comparison unit determines each metadata container that has changed in the file system within the time interval. The application programming interface buffers at least one identifier that corresponds to a metadata container that has changed in the file system within the time interval. The application programming interface packages and transmits the at least one identifier to the host. The at least one identifier is readable on the host.

摘要： An image-based backup backs up one or more snapshots of a volume without duplicating common data blocks. A backup engine receives a request to generate a backup image of a volume. In response to the request, the backup engine generates the backup image including data blocks and metadata describing attributes of the data blocks. The data blocks and the metadata arranged in the backup image in a same order as they were retrieved without imposing any additional ordering constraints on the data blocks and the metadata.

摘要： Image-based data restoration restores an entire image of a volume or selective files. A restore engine receives a request to restore data from a backup image that includes a plurality of data blocks and metadata describing attributes of the data blocks. In response to the request, the restore engine determines a restore mode. If it is determined to be a logical restore mode, the restore engine restores a file by retrieving the metadata associated with the file and the data blocks that are pointed to by the metadata. If it is determined to be an image restore mode, the restore engine restores an entire image of the volume by using the data blocks in the backup image without using the metadata.

摘要： An embodiment of the invention provides a traversal engine that traverses (walks) through metadata containers (e.g., inodes) in a file system and determines the metadata containers that have been modified (added, changed, deleted, or renamed) within a particular time interval. A modified metadata container corresponds to a data container (e.g., file or directory) that has been modified within the particular time interval. The traversal engine records, into a table, information about the modified metadata containers. The traversal engine also records, into the table, parent information corresponding to an immediate parent of a modified data container.

摘要： An apparatus to compare two datasets, each of which includes multiple data blocks, includes a comparison unit and a report generator. The comparison unit identifies block-level differences therebetween, by comparing block-level metadata between the first and second datasets, without comparing the contents of the data blocks. The report generator generates a human-readable report of the differences between the first and second version of the dataset, including the differences in individual data blocks between the first and second version of the dataset.

摘要： A system and method for conforming a metadata file associated with qtree of a storage system to a version used by a file system kernel of the storage system, where the version indicates a format of the metadata file. The metadata file stores state information with respect to each qtree, and may be located outside of the qtree structure. Major and minor versions are compared with latest known major and minor versions associated with the file system kernel. In response to such comparisons, the metadata file may be updated to a newer version, rolled back to an older version, and/or the system may enter a corrective state where further operations are performed.

摘要： A method and system for the copper anode refining is provided in which coherent jet technology is employed to heat the molten blister copper and/or melt scrap copper charges using a melting flame, oxidize the sulfur in the molten blister copper, and reduce the oxygen in the molten blister copper using top-blown coherent jet gas streams from one or more multi-functional, coherent jet lance assemblies. The present system and method employs a microprocessor-based controller operatively controlling the flow of an oxygen-containing gas, an inert gas, a reducing agent and a fuel to the coherent jet lance. The disclosed copper anode refining system and method greatly improves copper production while lowering oxidation/reduction cycle times and minimizing NOx emissions.

摘要： Methods, program products, and systems implementing dynamic parsing rules are disclosed. Log data from a variety of log producers can be parsed using parsing rules to generate information about an information system. The parsing rules can include system parsing rules and custom parsing rules. A state machine can be used to detect conflicts between various parsing rules. A central server can distribute the system parsing rules and custom parsing rules to one or more remote servers for distributed processing. In a hierarchical parsing system, a first tier parser can be used to identify types of sources generating the log data. Log data from each type of log source can be sent to a second tier parser that corresponds to the type of log source.
