摘要： Technologies for providing recovery point review within a continuous data protection system can support a data storage operator in a data recovery procedure. A snapshot image can be chosen that was made prior to a data loss event. A new writable snapshot can be created from this logged snapshot. The new writeable snapshot can become the target for recovering the data volume. Review can be performed in a forward direction by reading a journal of I/O operations that have occurred since the prior snapshot was made. Review can be performed in a backward direction by deriving a dirty data list of changes made to the data volume and then removing the changes as requested. The operator can continue forward and backward review operations to refine the selected recovery point. Upon establishing the desired recovery point, the new writable snapshot can be committed, or rolled back, onto the data storage volume.

摘要： Technologies are described herein for performing data de-duplication of a version of a data file for backup to a remote storage location. A CDP module executing on a computer creates a collection of files corresponding to the version of the data file by de-duplicating the version against a previous version master file stored locally on the computer. The previous version master file contains one or more unique data blocks of a specific block size from a previous version of the data file. Once the de-duplication against the locally maintained previous version master file is complete, the CDP module stores the collection of files corresponding to the version of the data file to the remote storage location. The remote storage location also contains a master file corresponding to the data file that contains all of the unique data blocks in the previous version master file.

摘要： Technologies are described herein for providing a power-save mode of operation for a continuous data protection (“CDP”) process. A CDP module executing on a computer detects when the computer is operating under battery power, and enters a power-save mode of operation. In the power-save mode, the CDP module monitors the state of the battery and restricts the CDP process based on a set of configuration settings specified for one of a number of zones, where each zone defines an upper and lower thresholds for a level of charge of the battery. If external power is restored to the computer, the CDP module restores the normal mode of operation for the CDP process.

摘要： A method, system, apparatus, and computer-readable medium are described for the background movement of data between nodes in a storage cluster. According to one method, exception tables are generated that include data identifying the areas on each node that need to be migrated to another node and the areas on each node that are to be migrated from another node. The exception tables may be generated in response to the failure of a node in the storage cluster or in other circumstances. A background resynchronization thread utilizes the contents of the exception tables to migrate data between the nodes of the cluster, thereby synchronizing the data stored on the nodes. Input/output operations directed to an area that is to be migrated from another node are redirected to the other node in accordance with a timeout period associated with the input/output operations.

摘要： Technologies are described herein for providing networked RAID in a virtualized storage cluster. The storage capacity of a storage cluster having two or more storage nodes is organized into tiers. A portion of the available storage capacity is allocated to one tier that is organized using chained declustering. Another portion of the available storage capacity is allocated to another tier that is organized using a networked RAID configuration. The storage cluster monitors the frequency at which data in the storage cluster is accessed. Frequently used data that is stored in the network RAID-configured tier is promoted to the chained declustered-configured tier. Infrequently used data that is stored in the chained declustered-configured tier is demoted to the network RAID-configured tier. The zone size for zones stored in the chained declustered-configured tier may be different than for zones stored in the network RAID-configured tier.

摘要： Technologies are provided herein for asynchronous data replication. A primary server maintains and exposes a storage volume for use by storage clients. The primary server receives write operations directed toward the storage volume and performs the writes on the storage volume. The primary server also creates buckets containing each of the write operations. The buckets are opened at a first point in time and closed at a second point in time that may be selected based upon the contents of the buckets, a predefined time period, or based upon an indication from an application program. The buckets are transmitted to a second server computer asynchronously. When each bucket is received completely by the second server, its contents are written to a storage volume maintained by the second computer. The buckets may be created from pages of a write-back cache utilizing a zero buffer copy mechanism.
摘要翻译：本文提供了用于异步数据复制的技术。主服务器维护并公开存储卷以供存储客户端使用。主服务器接收针对存储卷的写操作，并对存储卷执行写操作。主服务器还创建包含每个写入操作的桶。桶在第一时间点打开，并在第二时间点关闭，可以基于桶的内容，预定时间段或基于来自应用程序的指示来选择。桶被异步传输到第二台服务器计算机。当每个桶由第二服务器完全接收时，其内容被写入由第二计算机维护的存储卷。可以使用零缓冲器复制机制从回写缓存的页面创建存储桶。

摘要： Methods and systems for identifying candidates for de-duplication are disclosed herein. An example system may include: a de-duplication lister that coordinates with a kernel module to identify a unit of data for de-duplication and calculates a signature of the unit of data; a de-duplication queue that manages a de-duplication queue; a de-duplication tracker that maintains a de-duplication data structure including a plurality of entries corresponding to units of data and searches the de-duplication data structure to determine whether the signature of the identified unit of data matches the signature of at least one of the entries in the de-duplication data structure; a de-duplication maintainer that reviews the entries of the de-duplication data structure and removes obsolete entries from the de-duplication data structure; and a de-duplication engine that coordinates with the kernel module to perform de-duplication operations on the de-duplication queue.

摘要： Technologies for eliminating duplicate data within a storage system. De-duplication may be performed done at physical chunk level, where the data is not copied or moved to different location. A logical mapping is modified using a thin de-duplication kernel module that resides between a distributed volume manager (DVM) and a logical disk (LD). De-duplication is achieved by changing pointers in the mapping to land at a physical location. De-duplication is performed as post-process feature where duplicates are indentified and the duplicates are marked in the mapping table, thereby claiming free space through de-duplication. Block-level de-duplication in accordance with the above can co-exist with existing storage architectures for thin provisioning and snapshot management.

摘要： A method, system, apparatus, and computer-readable medium are described for providing distributed hot-spare storage in a redundant storage cluster. According to one method, a portion of the unutilized space on the storage cluster is utilized as a distributed hot-spare storage node. Through this mechanism, a redundant storage cluster with N storage nodes may be contracted to a redundant array with N−1 nodes. Thin provisioning and intelligent data placement may also be utilized to implement the distributed hot-spare storage node. Through repeated application of such methods and systems, the failure of any storage node or the sequential failure of multiple storage nodes within a redundant storage cluster results in the recreation of the cluster as a redundant storage array with one fewer node, but with the same redundancy.
