Backing Up Program using DOS 6.22

[docmolar]

I have a program called Mpddd on  C: that I would like to Backup to Floppies on A:   The program requires 8 formatted Floppies (so a simple Copy Command will not work). 

When I used Dos 5.0 I would type Backup C:\Mpddd A: at the C: prompt to backup the program  and it would worked well.  The backup process would stop when each Floppy became full and another Floppy was inserted.   This Command will not work with Dos 6.22.   Is it possible to Backup Programs with Dos 6.22?   What is the Dos 6.22 Backup Command to Backup program Mpddd to Floppies on A:
