I am fairly sure that DOS software to write CDs and the even earlier

to make it all work today on DOS might be something of a challenge.

Adaptec EasySCSI will provide a set of ASPI drivers...

Getting the network card to behave on the embedded box and then using
network shares might be the least difficult way out. The external PC can
run a modern OS that handles the backup process.

One of the old TCP/IP application stacks for DOS with FTP would probably
be an option. (assuming once loaded there is enough ram left to run the
CNC software ;-) Ah the joys of DOS emm/xms/umb management.
