摘要： Systems and methods herein obtain snapshots of one or more applications, while having minimal impact on performance of the applications. Embodiments may involve obtaining snapshots of modified application data within a node without disturbing the operations of the application. Systems may be configured to leverage the fast characteristics of local storage devices while utilizing the advantages provided by the remote storage of data. One or more applications may be preconfigured to record data modifications in one or more associated application state storages located on local memory. Further, one or more systems may operate in the background to identify modifications made to the associated application state storages and to determine an appropriate moment to take one or more snapshots of the stored data and transfer the one or more snapshots to one or more remote locations to be stored. Several factors may be used to determine when an appropriate moment has occurred.

摘要： One or more snapshots of data stored over a period of time are maintained in a hybrid storage device comprising a magnetic disk and a solid state disk, wherein a selected snapshot stores information that allows recovery of data that is stored in the hybrid storage device at a selected point in time of the period of time. The hybrid storage device receives an input/output (I/O) command from a computational device. A category of a plurality of categories to which the I/O command belongs is determined, wherein the plurality of categories comprise writing to an unused block, writing to a used block, reading from an unused block, and reading from a used block. In response to determining the category to which the I/O command belongs, the I/O command is handled by one of the magnetic disk and the solid state disk based on the determined category.

摘要： A system and method efficiently removes ranges of entries from a flat sorted data structure, such as a fingerprint database, of a storage system. The ranges of entries represent fingerprints that have become stale, i.e., are not representative of current states of corresponding blocks in the file system, due to various file system operations such as, e.g., deletion of a data block without overwriting its contents. A deduplication module of a file system executing on the storage system performs a fingerprint verification procedure to remove the stale fingerprints from the fingerprint database. As part of the fingerprint verification procedure, the deduplication module performs an attributes intersect range calculation (AIRC) procedure on the stale fingerprint data structure to compute a set of non-overlapping and latest consistency point (CP) ranges. During the AIRC procedure, an inode associated with a data container, e.g., a file, is selected and the FBN tuple of each deleted data block in the file is sorted in a predefined, e.g., increasing, FBN order. The AIRC procedure then identifies the most recent fingerprint associated with a deleted data block. The output from the AIRC procedure, i.e., the set of non-overlapping and latest CP ranges, is then used to remove stale fingerprints associated with that deleted block (as well as each other deleted data block) from the fingerprint database. Notably, only a single pass through the fingerprint database is required to identify the set of non-overlapping and latest CP ranges, thereby improving efficiency of the storage system.
摘要翻译：系统和方法有效地从存储系统的平坦排序的数据结构（诸如指纹数据库）中去除条目的范围。条目的范围表示由于各种文件系统操作，例如删除数据块而不覆盖其内容，已经变得陈旧的指纹，即不代表文件系统中对应的块的当前状态。在存储系统上执行的文件系统的重复数据删除模块执行指纹验证过程以从指纹数据库中移除陈旧的指纹。作为指纹验证过程的一部分，重复数据消除模块在陈旧的指纹数据结构上执行属性相交范围计算（AIRC）过程，以计算一组非重叠和最新的一致性点（CP）范围。在AIRC过程期间，选择与数据容器（例如文件）相关联的inode，并且以预定义的例如增加的FBN顺序对文件中每个被删除的数据块的FBN元组进行排序。然后，AIRC过程识别与删除的数据块相关联的最新指纹。然后使用来自AIRC过程的输出，即一组非重叠和最新的CP范围，以从指纹数据库中删除与该删除的块（以及每个其他已删除的数据块）相关联的陈旧的指纹。值得注意的是，仅需要一次通过指纹数据库来识别一组不重叠和最新的CP范围，从而提高存储系统的效率。

摘要： A method is used in managing snapshot in cache-based storage systems. A request to create a snapshot of a data object is received. A portion of the data object is cached in a global cache. The data object is associated with a mapping object. The mapping object manages access to the portion of the data object. A snapshot of the data object is created. A snapshot mapping object is associated with the snapshot of the data object. The snapshot mapping object includes a link to the mapping object. The snapshot mapping object is a version of the mapping object and shares the portion of the data object cached in the global cache.

摘要： Systems and methods are provided which perform a file level restore by utilizing existing operating system components (e.g., file system drivers) that are natively installed on the target computing device. These components can be used to mount and/or interpret a secondary copy of the file system. For instance, the system can instantiate an interface object (e.g., a device node such as a pseudo device, device file or special file) on the target client which includes file system metadata corresponding to the backed up version of the file system. The interface provides a mechanism for the operating system to mount the secondary copy and perform file level access on the secondary copy, e.g., to restore one or more selected files.

摘要： A method of performing a data write on a storage device comprises instructing a device driver for the device to perform a write to the storage device, registering the device driver as a transaction participant with a transaction co-ordinator, executing a flashcopy of the storage device, performing the write on the storage device, and performing a two-phase commit between device driver and transaction co-ordinator. Preferably, the method comprises receiving an instruction to perform a rollback, and reversing the data write according to the flashcopy. In a further refinement, a method of scheduling a flashcopy of a storage device comprises receiving an instruction to perform a flashcopy, ascertaining the current transaction in relation to the device, registering the device driver for the device as a transaction participant in the current transaction with a transaction co-ordinator, receiving a transaction complete indication from the co-ordinator, and executing the flashcopy for the device.

摘要： Methods, apparatus, and computer-accessible storage media for controlling export of snapshots to external networks in service provider environments. Methods are described that may be used to prevent customers of a service provider from downloading snapshots of volumes, such as boot images created by the service provider or provided by third parties, to which the customer does not have the appropriate rights. A request may be received from a user to access one or more snapshots, for example a request to export the snapshot or a request for a listing of snapshots. For each snapshot, the service provider may determine if the user has rights to the snapshot, for example by checking a manifest for the snapshot to see if entries in the snapshot manifest belong to an account other than the customer's. If the user has rights to the snapshot, the request is granted; otherwise, the request is not granted.

摘要： An interface between a local file system and a data store (e.g., a “write-once”store) generates and exports to the data store a “versioned” file system. The state of the local file system at a given point in time can be determined using the versioned file system. The versioned file system comprises a set of structured data representations that comprise metadata associated with actual file system data. The interface creates and exports to the data store structured data representations, which correspond to versions of the local file system, as well as the actual file system data that these structured data representations represent. A cache associated with the interface stores recently used data and metadata, as well as write data and metadata waiting to be transferred to the data store. Prior to transfer, data transformations, such as compression, encryption, and de-duplication, may be applied to the data and metadata.
