 NAME
     BACKUP -- Copies all the files on a disk to another disk
 
 ABBREVIATION
     b <shift> A

 SYNOPSIS
     BACKUP D<src_drive> TO D<trg_drive>[,ON U<unit>]

 FUNCTION
     This command copies all the files on a disk to another disk on a dual 
     drive system. You can copy onto a new disk without first using the 
     HEADER command to format the new disk because the BACKUP command copies 
     all the information on the disk, including the format. You should always
     BACKUP important disks in case the original is lost or damaged.
     Because the BACKUP command also HEADERS disks, it destroys any 
     information on the disk onto which you're copying information. So if 
     you're backing up onto a previously used disk, make sure it contains no 
     programs you wish to keep.
 
 INPUTS
     <src_drive> - source drive number
     <trg_drive> - target drive number
     <unit>      - target drive unit number
 
 RESULT
     The contents of the source disk is copied to the target disk.

 EXAMPLES
     BACKUP D0 TO D1
         Copies all files from the disk in drive 0 to the disk in drive 1.

     BACKUP DO TO D1, ON U9
         Copies all files from drive 0 to drive 1 in disk drive unit 9.
 
 NOTES
     This command can only be used with dual disk drive.
