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： A technique for eliminating duplicate data is provided. Upon receipt of a new data set, one or more anchor points are identified within the data set. A bit-by-bit data comparison is then performed of the region surrounding the anchor point in the received data set with the region surrounding an anchor point stored within a pattern database to identify forward/backward delta values. The duplicate data identified by the anchor point, forward and backward delta values is then replaced in the received data set with a storage indicator.
摘要翻译：提供了一种消除重复数据的技术。在接收到新的数据集之后，在数据集内识别一个或多个锚点。然后，在包含存储在模式数据库内的锚定点周围的区域的接收数据集中围绕定位点的区域执行逐位数据比较，以识别前向/后向增量值。由锚点，前向和后向增量值标识的重复数据随后用存储指示器在接收的数据集中替换。

摘要： A system and method for calculating and storing block fingerprints for data dedu- plication. A fingerprint extraction layer generates a fingerprint of a predefined size, e.g., 64 bits, for each data block stored by a storage system. Each fingerprint is stored in a fingerprint record, and the fingerprint records are, in turn, stored in a fingerprint database for access by the data deduplication module. The data deduplication module may peri¬ odically compare the fingerprints to identify duplicate fingerprints, which, in turn, indi¬ cate duplicate data blocks.
摘要翻译：一种用于计算和存储用于数据挖掘的块指纹的系统和方法。指纹提取层针对由存储系统存储的每个数据块生成预定义大小的指纹，例如64位。每个指纹被存储在指纹记录中，指纹记录又被存储在指纹数据库中以供重复数据删除模块访问。重复数据删除模块可以对指纹进行比较，以识别重复的指纹，这反映了重复的数据块。

摘要： A system and method for managing data deduplication of a storage system utilizing persistent consistency point images (PCPIs). Once a target PCPI of a data transfer is generated, a backup management module of the storage system alerts a data deduplication module to begin deduplication of the data contained within the target PCPI. Once the deduplication procedure has been completed, the active file system of the storage system has been deduplicated, however, the target PCPI remains un-deduplicated. In response, the backup management module generates and exports a revised target PCPI. The previous target PCPI may then be deleted, thereby transitioning the exported PCPI's image of the state of the file system to a deduplicated state.
摘要翻译：一种使用持久一致性点图像（PCPI）来管理存储系统的重复数据删除的系统和方法。一旦产生了数据传输的目标PCPI，则存储系统的备份管理模块警告重复数据消除模块以开始重复数据删除目标PCPI中包含的数据。重复数据删除过程完成后，存储系统的活动文件系统已被重复数据删除，但目标PCPI保持未重复数据删除。作为响应，备份管理模块生成并导出修订的目标PCPI。然后可以删除先前的目标PCPI，从而将导出的PCPI的文件系统的状态的图像转换为重复数据删除的状态。

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 patient monitoring device and method that determines and monitors at least one patient parameter is provided. A configuration processor generates configuration information in response to a first input signal and an adaptive notch filter receives a second input signal. The second input signal includes a signal of interest and an interference signal in a predetermined frequency range. The adaptive notch filter automatically estimates the interference signal within the second input signal based on a filter parameter and removes the estimated interference signal from the second input signal to generate a target signal. A step processor is electrically coupled between the configuration processor and the adaptive notch filter and sets a value of the filter parameter based on the configuration information, wherein the adaptive notch filter uses the filter parameter to reduce a ringing artifact on the target signal below a threshold level.
