When my Radon mitigation system was installed, part of the process was to install a sealed sump pit cover like you described: a viewing port in the top and sealed around the edge.
If the pump fails, water will continue to accumulate until it finds the path of least resistance, which would probably be the caulking around the edge of the sump pit cover.
As far as back-up sump pumps, I use the Basement WatchDog "Big Dog". This has a 12 volt battery to provide pumping in the event of power failure, but the pump can also run off 120 volts if the power has not failed. I find this feature important because if the main pump fails (as in jams or burns out), you are not running down the battery while 120 volts is still available.
