[Coco] Backup of HDB-DOS drives

I'd like to backup HDB-DOS drives from one device to another. I have SCSI 
drives. Perhaps I could use BACKUP in a loop but don't know if it's possible 
for HDB-DOS to address two different devices.

I'm thinking of using NITROS9 with a device descriptor set up for source and 
destination HDB-DOS, open each as a raw device, and copying 256 * 35 * 18 
bytes. Do we have a program like Linux's 'dd' ?

===========================

For my RGB-DOS system I wrote a FOR : set drives : BACKUP :switch drives : 
BACKUP : NEXT loop from one hard drive to my ram drive and back to the other 
hard drive.  I never did find any was to copy directly from one hard drive 
to the other.
