The drain pipe has a blockage somewhere downstream from where the toilets are connected to the main sewer line from the house. All the drains in a house normally connect to one main line that either goes to the city sewer system or your septic tank. If you know where the sewer line exits the house, you could check there to see if the blockage is in the yard. Most sewer blockages are caused by tree roots, broken fittings, or crushed pipes. Good Luck
Most sewer lines do not run perfectly straight, also, you would not be able to get it into the main because there is an elbow where it connects. You can put copper sulphate down the line to kill the roots. Do it a couple of times a year.
on a main line they should be installed at a minimum of every 100'. Also any turning radius 135* or more. Every main line needs an end of a line clean out. Every fixture that is more than 5' from a main line requires a clean out. Probably other places that cleanouts should be used as well. I install usable clean outs at all fixtures in install no matter where or what they are, because you never know when you may need to use them. I also install clean outs on the main sewer line right after it exists a building . This is all off top of my head. Cleanouts are a plumber and homeowners friend,I install as many as i can.Ideally and most modern plumbing codes require a CO every 100 ft, or every change of direction greater then 45 deg and , at the base of every soil stack .The maximum should be no more then 100 ft as most 1/2 - 3/4" drum machines have a capacity of 100' of cable although another drum can be added (up to 200') it is just good plumbing practices to have the CO's not to exceed the average drain cleaning cable machine.Many installers are not into repair /drain cleaning and have the I don't care mindset as once they install the lines you never hear from then again.
if you are fitting a maserator unit like Saniflo you can go horizontally up to 100 meters or vertically up to 4 meters but you must have a 1 in 200 gravity fall on the horizontal there is no certain distance it can be from the main. it all depends on the fall and how deep your sewer is, however it does matter how many bends your line has. It shouldn't exceed 135 degrees or 100' without a cleanout.
Either they are on a separate sewer line and connect to the main sewer line later on or they sewerage is pumped by means of a machine into the main sewer line.
Not exactly a sewer main normally flows by graviety and a forced main is a pumped system
A 3 or 4 inch pipe sticking straight up out of the ground? This is the clean out for the sewer line. If sewage is coming out of it, this means the sewer line is clogged or collapsed from there to the main city sewer. If you have a septic tank, the tank is full and needs to be pumped out.
The obvious and main problem (and reason to keep your sewer lines clean) is because a backed-up sewer line means that sewage can get backed up into sinks and bathtubs. This is unsanitary and a health hazard. A broken sewage line is costly to repair.
3" house (building) drain allowable. 4" building sewer line needed for house from sewer main.

Every home owner should be knowledgeable about their sewers and drains. It is necessary to have them cleaned periodically. The main sewer line should be clean and drains should be grime-free.

You may not have a backflow preventer in the main line. This prevents anything coming back from the main line. It may be coming from your neighbors above you on the line.
A water or sewer main is as it sounds ,It is the main feed line that runs underground usually along side a street or easement from your house or place of business to connect you to these utilities.
