I have a customer, with a DK280 and a Stratagy 8 Voice mail that wants to back up her messages every night. What's the best way to go about this. She's been told that a comlete backup takes 4 hours and about 20 floppy disks, is there a better way?

Whats a SG-8? I'm aware of the 4, 6, 24. Anyway, I think thats the only way to do it. She needs the admin program on her PC and the serial cable. Its very slow and takes20 or 30 floppy's.
