There are always ways in which your backups can go wrong and not be
readable, and I'm not arguing that here.
But 9 track tapes have turned out to be pretty spectacularly long-lived.
I've personally read tapes that were stored for 30+ years in
unconditioned spaces.
Contrast that with the write only exabyte tapes. I lost some stuff to
those.
There is a reason that exabyte no longer exists. It used to take up a big
swath of central Boulder.
