The special about InterNIC is that they don't trace you. Besides Uplink that's the place you can connect directly without fear of being traced.
Now to try and answer all of your questions.
Admin-access servers - I mean servers to which you have admin password. The process of this is to bounce to that server, run monitor bypass then password cracker, disconnect when the latter is done and clean up at InterNIC. Going through them means that an eventual trace will take longer time.
3-4 servers - The probability for a trace is low (but you may make a mistake such as not engage the monitor) and as such, a low bounce route like that will give you time enough to get out of there should a trace be initiated and enough time to delete logs on at least one of them.
The two "good" log delete spots are Uplink Test Server and InterNIC. My bounce route is usually Gateway to InterNIC to Uplink Test Server. Removing the logs at Uplink test server by bouncing through uplink hardware is considered safe. Removing InterNIC logs is safe as per default as you remove the bounce logs and "logged in as admin from xyz" and they never ever trace you. In theory, InterNIC is enough, but I've been caught even when with them.
The "backing up" process works perfectly fine. I used it while still making zillions of mistakes with my hacks, but I recommend stopping to use it once you're off the training wheels.
If anything is still unclear, just ask.
