If you want to do it the old-school way, you could use Boot Tape Back-Up Plus, a cassette-based software for backing up boot tapes.
As the old ads in Analog magazine read:

At last, an inexpensive and easy way to mal<e back-up copies

copy of your autoboot macfiine language programs to
provide you witti an identical copy to store away for safe

Professionals make a back-up copy of everyttiing. At minimal
cost, you can now protect your large investment in software
the same way. BOOT TAPE BACK-UP is simple to use and will
pay for itself many times over. Don't put your precious

I happen to even have an original copy of such a cassette, though I don't seem to have a 410 recorder any more, nor the manual for it, that I've seen recently.
