You want to drop them completely (i.e. not count them at all, which would
mean your monthly totals would underreport how much you backed up), or you
want to somehow account for the fact that "incr for day NN/MM/YYYY includes
changes from NN/MM-1/YYYY too"?

I've done something similar, but not to the point where I treat
"accumulated incrs" specially -- I just assume that if three days were
missed for a particular client then the amount of data that was backed up
during the next incremental should be averaged over the number of days
missed. I *don't* currently have my backup reporting scripts reporting
this average -- they just show `0' MB for one day, and a larger than
average number for the next day, and then I eyeball average it.
