Mechanisms and techniques are disclosed that provide the ability to backup and restore a file between a backup server and a data storage system using multiple trails of data for the same file. Within the data storage system, the file is generally stored as a series of data portions spread across multiple storage devices such as disk. The file may be stored, for example, within a volume. In the backup operation of the invention, a discover phase determines which respective data portions of the file (e. g. , partitions) are stored upon which respective storage devices (e. g. , disks) of a plurality of storage devices. The system then designates individual respective backup devices (e. g. , tapes) of a plurality of backup devices to be used for backing-up respective individual ones of the data portions of the file that are stored on respective storage devices. Next, the system concurrently backs up at least two respective data portions of the file to different respective backup devices for which those data portions are designated, such that at least two respective data portions of the file are backed-up to respective backup devices in parallel. The restore operation operates in a similar manner by determining which respective data portions (e. g.

A system for efficiently representing or âmappingâ data so that it can be rapidly communicated to a back-up storage system from a primary processor or a shared storage device while at the same time allowing a backup system to backup files rather than devices is described.

A system for providing high speed external backup and restoration of data in a data storage system. Individual data objects are backed up in logical order on backup media such as magnetic tape so that they may be retrieved individually. Minimized descriptions of backed up data are transmitted between the host and backup systems to control high speed transfer of data between data servers and backup devices on a separate data channel. The descriptions are manipulated by the backup system to comply with formats of any number of host systems and data storage systems and to efficiently map the backed up data onto the backup devices. The system also provides for restoration of data to the data storage system by using a host system to pre-allocate space for the restored data, obtaining mapping information for the allocated space from the host system, and then directly writing the restored data into the allocated space, based on the mapping information.

Methods and apparatus for reducing resource contention in parallel data backup processes that share a variety of resources in a computer environment to access target data to be backed-up. The target data is distributed among the backup processes based on an availability of one or more resources in the computer environment used by a backup storage system to access the target data. In one example, each data file of the target data is assigned to a particular backup process based on the availability of one or more resources and a total size of the target data. The data files of the target data are assigned to the backup processes such that each backup process backs-up a respective portion of the target data, and such that the collection of backup processes that make up a backup operation are completed in a shortened time as a result of reduced resource contention. The target data originally may be located, for example, in one or more host computer systems, one or more primary storage systems, other computer devices containing a storage medium, or combinations thereof.
