Hi giblets 
Do you have a tank at home as well? Or, do you know someone else who does? If so, as a back up measure, you can set up another filter in that tank so that it will be seeded with beneficial bacteria and ready to put into your other tank when the power is back on. This could be as simple as an inexpensive little air pump and box filter. Then, if the worst happens, it could take over the filtration while your regular pump gets reestablished. Later the pump could power an airstone to make an attractive display.
It will also help to manually circulate the water by dipping it out and pouring it back in from a height. Also, if you stop feeding your fish, they will produce less waste which will reduce the load on the bacteria.
Daily water changes will do little to harm the beneficial bacteria, but will reduce chemical pollution and add oxygen, which are very important factors. I strongly recommend that you do them for the duration of the power outage.
Good luck.
