摘要： Read-ahead of data blocks in a storage system is performed based on a policy. The policy is stochastically selected from a plurality of policies in respect to probabilities. The probabilities are calculated based on past performances, also referred to as rewards. Policies which induce better performance may be given precedence over other policies. However, the other policies may be also utilized to reevaluate them. A balance between exploration of different policies and exploitation of previously discovered good policies may be achieved.

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： 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： 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.
