Yes, you should feel comfortable with your vendor, but don't.  The worst
time to find out your inventory is off is when you are trying to recover
from a disaster.  I highly recommend (and this is from experience) that you
audit your vault at least twice a year.  Even with all the safeguards,
problems can happen.
