  Thanks, I've pulled winston already with a similar wget command. It took
about 6 hours as it only came in at about 800 KB/s average.

  Yes re-read and so went for the first grab. I'm new to the mailing list but
have been around long enough to know that resources for Parabola are not
limitless. Thus the asking about preferred methodologies

I'll probably have to limit my downloads a bit as I'm doing this over my
residential ISP line. (Fiber) There is no stated cap but I still want to be a
little cautious about multi hour/multi GB downloads.

I'll have to ponder the best balance, and I do understand about incremental
backups but thanks for the reminder. 

I'll work with the winston back-up for a bit.. Get a good routine at my end..
then I'll see about adding proton.

Yep, I'm just being cautious and not wanting to step on toes or accidentally
knock something over.
