I am assuming this is some leftover PID or SOCK file that needs to be renamed or removed. Running ps -ax does not show any process running under pid 1289 or by the name BackupPC. Any ideas?

BackupPC keeps track of its own PID/status independently of systemd (or whatever else is launching/monitoring it) in a file called "status.pl," which can usually be found in /var/log/BackupPC, unless you or your package manager have placed it elsewhere.
You'll find the relevant variable under "pid" within this file, which as I recall, you can either blank out, or set to zero. (I note that status.pl contains a number of other things, so you probably don't want to just delete it.)
My own systemd uses helper scripts to coordinate the state of status.pl with the pidfiles and systemd, something which I thought was ridiculous overkill when I saw the considerably simpler systemd's on this list (and that's probably still the case) but it's something to consider if this happens frequently.
