Parameters

   input-specifier


   Specifies the input for the BACKUP operation as either a file
   specification, a BACKUP save-set specification, or a device name.
   If the input specifier is a save-set specification on disk, you
   must include the input save-set qualifier /SAVE_SET.

   You can specify DECnet node names in save-set specifications
   only. You can use wildcards characters in file specifications,
   and in save-set specifications if they are on magnetic tape.

   output-specifier

   Specifies the output for the BACKUP operation. The output
   specifier, like the input specifier, can be either a file
   specification, a BACKUP save-set specification, or a device name.
   If the output specifier is a save-set specification on disk, you
   must include the output save-set qualifier /SAVE_SET.

   You can specify DECnet node names in save-set specifications
   only. You can use wildcard characters when the output specifier
   is a Files-11 volume, but not when the output specifier
   is a BACKUP save-set specifier or a volume created by a
   BACKUP/PHYSICAL or BACKUP/IMAGE operation.
