You're correct that it's good to make backups, but that wasn't my
initial goal. My initial goal was to refute the claim that the DVD-R
copy will "look better" than the original VHS. A copy will never look
better than the original.
As for particle shedding, that's the result of storing them in a humid
environment. If kept dry with an air-conditioned home and/or dry gel
packs, the tapes will survive. Look at Twilight Zone..... 40 years
old and the original tapes from season 2 are still good.
I doubt the dyes on a recordable-DVD will last that long. The dye
will fade.

Actually, it's a good idea to "exercise" your tapes every 2-3 years
with a fast-forward and rewind. Or just sit-down and watch the
original tape (rather than the dvd copy).
Personally:
I have yet to experience the "flaking" problem. In fact, I'm still
using my original tape that I bought in 1986 with my new VCR. It sees
weekly usage, but it still works after all these years. No flaking of
the magnetic particles.
Experts claim:
Various sources say that tapes made between 1975 and 1985 are the
poorest-quality. In 1975, manufacturers were trying to replace
natural ingredients with synthetics, and they failed. Tapes from that
era quickly degenerate. ----- Post-1985 they discovered the problem,
switched to more humidity-resistant plastics, and created more stable
tapes.
