Abstract

In one aspect, a method includes determining a number of data streams to assign to a volume, assigning a fragment file for each data stream, sending fragment files to a backup storage device, synthesizing the fragment files to form an image file for the volume at the backup device, sending new fragment files with changes to the volume to the backup device and synthesizing the new fragment files with the corresponding image file to form a new image file for the volume.
