~~~~~~~~~~~~~
The BACKUP command creates a system disk that includes a Digital-
provided set of volume parameters, including a CLUSTER_SIZE (disk
access scheme) of one. (The CLUSTER_SIZE refers to the way files are
stored on the disk, NOT to VAX.clusters.) You can change most volume
parameters later with the SET VOLUME command. However, to change
the CLUSTER_SIZE you must back up the system disk to a disk that has
been previously initialized with the CLUSTER_SIZE that you want. To
prevent the BACKUP command from reinitializing the target disk, use
the /NOINITIALIZE qualifier. For more information about initializing a
