I think I understand your want in that you would like to have backuppc check that a drive is hooked up before trying to use it for backups. If I am correct then I would suggest you build a quick daemon script that starts backuppc when the device is hotplugged and stops backuppc when unplugged. I dont know what your linux distro is but hotplug scripts are pretty easy, do some google work to get the file and method for a hotplug script on a specific device.
