Should a badly placed “rm” command occur on the system, the
system and both of its backup disks would be wiped clean. I
don't believe the risk mentioned here over was related to disk
decay. It was more about minimizing the time frame when this
catastrophe could happen.
I wouldn't do both backups at the same time personally, If
something very wrong occurs to the system at backup time, I'd
still have the secondary backup available for restore.
Things are a bit different when centralizing backup policies
with tools like Amanda.

Interesting opinion, it could be worth verifying. Keeping a
machine running for BOINC, I only had a disk issue once since
the beginning of the decade. Building disks has energy costs
too indeed.
