A system and method for backing up a data set are provided. The system comprises a tape backup system comprising a number of physical tapes for storing data; and a processor. The processor is configured to generate at least two portions of data from the data set, wherein each portion of data respectively contains a distribution of a respective subset of the data set, and the data set is restorable from at least two portions of the at least two portions of data; to access a logical mount point of the tape backup system that points to the number of physical tapes; and to apportion each of the at least two portions of data among the number of physical tapes pointed to by the logical mount point. To restore a data set, a processor is configured to access a logical mount point of a tape backup system that points to the number of physical tapes; to receive, from the logical mount point, data identifying each of the number of physical tapes; to retrieve, from each of at least two of the number of physical tapes identified by the data received from the logical mount point, the portion of data from the data set stored on the physical tape; and to recombine the retrieved portions of data to restore the data set. |
