We run amcheck once before end of business day to ensure the (right)
tape is in.

Our back-up script also runs amcheck, but doesn't use it to determine
whether to run amdump.  Instead it uses it to determine whether to do a
verify and eject the tape.  If amcheck does not exit 0 just before
amdump is run, then the tape isn't verified or ejected so that we can
better deal with the issue in the morning.  The reason why we want
amdump to run anyway is that we at least want partial disk dumps.
