    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： 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： 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.
