I was replying to this thread because I thought I saw the same issue. However, I just caught Checkmate throwing up the dialog and saw that "backupd" was running for a short period of time. Apparently backupd can wake up and run for a short time without actually doing a TimeMachine backup.
There has, however, been a change in Checkmate behavior. If these dialogs were thrown they would eventually dismiss and not 'stack up' like they have done the previous two nights. I have another machine running same latest High Sierra without seeing these dialogs accumulate.
{Aside: some issue with web site. I cannot Preview nor can I add a file to show the process running.}
