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： 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： For block level backup, a full image level backup is created of a file system from production storage at a production server to random access storage at a backup server. A mounted image is created from the full image that exposes a block level representation of the file system of the production server for read operations in a file level format. File enumeration is performed on the mounted image for files. Block level read operations are monitored while the files are being enumerated. During monitoring, blocks that are read for the read operations are marked as meta-data blocks. Blocks that are not marked as meta-data blocks are identified as data blocks. The data blocks are migrated to sequential storage, while leaving the meta-data blocks on the random access storage, wherein the data blocks form a backup image.

摘要： An exposed Internet Small Computer System Interface (iSCSI) target of a backup repository is defined as a source of, and a storage volume to be recovered as a target of, a mirrored pair of storage resources. The iSCSI target represents a point-in-time backup snapshot. Data from the iSCSI target is synchronized to the storage volume. The mechanisms of the illustrated embodiments leverage iSCSI with Instant Restore to reduce a Recovery Time Objective (RTO) and provide a secure transport when recovering a volume over a WAN.
