  Disk-to-disk BACKUP operations? 
 The Question is:
 
I am trying to replace the user disk (and eventually the system disk) with a
 larger DEC/Compaq drive. Can I do a disk-to-disk copy?
 
Is the BACKUP command the best / only way to do this?  Is there a resource
 which deals specifically with copying hard drives?  The BACKUP info seems to
 be geared mainly to tapes.
 
Thanks Wizard!
 
 
 
 The Answer is :
 
  The OpenVMS Wizard would use BACKUP for this task.  For details on the
  BACKUP command and its uses, and specifically for BACKUP disk-to-disk
  operations, please see the BACKUP manual and the OpenVMS System Manager's
  Essentials manual.
 
  You will need to have the input and output disk devices mounted per the
  documentation, but the INITIALIZE and BACKUP commands required are:
 
    $ INITIALIZE target-ddcu: volume-label -
        /HEADER=x /MAXIMIM_FILES=y /CLUSTER_SIZE=z /SYSTEM
 
    $ BACKUP source-ddcu: target-ddcu:/IMAGE/NOINITIALIZE
 
  Depending on the value of the data and the trust you have in the disks,
  you may want to use /VERIFY.
 
  Again, the BACKUP Utility manual and the System Manager's Essentials
  Manual has details on using BACKUP.
 
  For information on the /HEADER, /MAXIMUM_FILES and /CLUSTER_SIZE
  calculations for disk volumes, please see topic (7884).
