A quick tutorial, except when new or just pumped out, a septic tank is normally full. Put some waste in, some liquid must come out. If it can't go somewhere, it will rise in the tank and potentially back up the line.
The leach field is where the liquids go, and the inlet plumbing is laid out so that solids can fall to the bottom of the tank preventing them from going to the outlet unless the tank is full of solids. If the tank is not maintained properly by pumping out those solids, they can be pushed out into the leach fields. If that happens often enough, it can clog up the soil so it absorbs moisture very slowly, so any large input cannot be handled since there's no place for it to go, it backs up until enough has leached into the ground. Unless the soil is saturated from precipitation or surface runoff, it should be able to handle the inlet volume if it was designed and installed properly.
It may well be that your leach field is shot, and it would require replacement. But, if it's that the ground is saturated, not a lot you can do. If you were to rebuild the leach field, more sand and gravel in the prep so that it perks better.
On a septic system, it's probably not a good idea to have a garbage disposal, and never pour any grease down the drain.
