摘要： Embodiments for data tagging in a computing environment are provided. A write operation in an operating system (OS) file system level storage layer is intercepted. A set of signatures in a sub-chunk level is calculated. The set of signatures are aligned to the beginning of an OS file system-level object and stored in a memory location, such as a cache, along with file system information relating to the write operation and to the file system-level object that the data is written into. Following file system processing, and as the data is written into storage in blocks, the write operation is intercepted in the block level storage layer. A secondary set of signatures in a sub-block level is calculated using a common algorithm used to create the original set of signatures. The sets of signatures are compared against each other, and blocks of the data having matching signatures are tagged with the file system information stored in the memory location.

摘要： Described is a method, system, and computer program product for selecting a data repository within a computing environment. The data repository can exist on multiple target computing systems as a logical entity called a volume or a file system. When selecting at least one data repository, a data protection system of the computing environment analyzes the incoming data from a source computing system, in conjunction with information describing the data repositories. The data repository information, or repository characteristic information, can be stored on a repository volume table (RVT) of the data protection system. By determining a weighted selection score from the analysis of all the information available to the data protection system, the data protection system can intelligently select a data repository for storing data from the source computing system. Further, by tracking repository characteristic information on a continuous or periodic basis, the data protection system can enable emulated views of data that has been stored on the data repositories of the computing environment.

摘要： Techniques for adjusting the frequency of data backups and initiating event-driven backups in a storage system are disclosed herein. In one embodiment, a self-adjusting backup frequency, known as a “Change Rate Objective,” is defined to conduct or delay backups for one or more volumes in the storage system on the basis of an associated policy value. The Change Rate Objective may be tied to one or more business or data activity events, such as the amount and type of data changes since a last backup. The storage system may also be tailored to conduct or delay full or incremental backups on the basis of a Change Rate Objective that measures whether a full or incremental or differential backup is more appropriate. Various data or system failures, or data or business events may also be used to adjust the retention periods of continuous data protection (CDP) data and delay a rollup of CDP data.
摘要翻译：在此公开了用于调整存储系统中的数据备份频率和启动事件驱动备份的技术。在一个实施例中，被称为“变化率目标”的自调整备份频率被定义为基于相关联的策略值来执行或延迟存储系统中的一个或多个卷的备份。变更率目标可能与一个或多个业务或数据活动事件相关联，例如自上次备份以来数据更改的数量和类型。存储系统还可以被定制为基于改变率目标来执行或延迟全备份或增量备份，该目的是测量完全备份或增量备份或差异备份是否更合适。也可以使用各种数据或系统故障或数据或业务事件来调整连续数据保护（CDP）数据的保留周期并延迟CDP数据的汇总。

摘要： A first computational platform generates a data structure that indicates a set of blocks, wherein the indicated set of blocks have to be rewritten to revert a logical storage structure stored in the first computational platform to a previous state. An Input/Output (I/O) request that corresponds to a read operation on a selected block of the logical storage structure is received. A determination is made from the data structure that the selected block has to be rewritten to revert the logical storage structure stored in the first computational platform to the previous state. The first computational platform receives the selected block from a second computational platform, in response to a request made by the first computational platform to the second computational platform for the selected block.

摘要： Provided are a computer program product, system, and method for restoring objects in a client-server environment. An entry is added to an index for each chunk identifier. Each index entry includes one of the chunk identifiers and a reference to the chunk of data in the target storage from which the chunk identifier was calculated. A request is transmitted to a server recovery agent to recover an object from the storage server. Chunk identifiers of chunks of data in the requested object to recover are received from the server recovery agent. A determination is made from the index of whether the received chunk identifiers for the requested object matches the chunk identifiers indicated in the index. A request is made of the chunks from the server recovery agent for the received chunk identifiers not matching chunk identifiers in the index entries.
