Abstract
A technique for restoring file systems by applying full and incremental backups together while streaming them from multiple devices provides a faster system restore from a full backup where incremental backups must also be applied. A first storage device streams the full backup while at least one second storage device streams at least one incremental backup. As files are detected in the incremental backup, they are written instead of the corresponding file in the full backup. Incremental backups can be pre-merged to reduce their number to one less than a number of storage devices available to stream the backups, so that the full backup can be streamed along with the pre-merged incremental backup(s) to restore the file system.
