Restoring a volume to eliminate disk fragmentation
During the course of creating, deleting, and modifying files, a disk
can have sections of files scattered across it. The files, though
scattered, are linked by software so that a file appears contiguous
when it is displayed for you. Eventually the disk can become
severely fragmented, and system performance suffers.
When a disk stores files contiguously, system performance improves,
and the wear and tear on the disk mechanisms is minimized because
fewer searches are performed for the sections of a file.
When you restore a volume from a save set, BACKUP Manager
places the files contiguously on the disk. To eliminate disk
fragmentation, you can perform a backup of the disk and restore the
backup copy.
