Worked on a place long ago, that anything they needed to save offline from more than a few decades where stored in microfilm, the expectancy there where they would last 80 to 100 years.
Anything else was pretty much tape.
You also take in account the technology avaiability. The more complex is to use, harder will it be to reproduce in the future. Even with tapes, you might want to copy the data to another tape/recorder every decade or two, to keep it on par with the technology.
a. Change your blades often, with a safety razor you most likely want a new blade after each shave. Blades get dull, pull the hair and clog the pores, they will accumulate bacteria over time, causing infections, disposing them after each shave will reduce the chances of those happening.
b. Try to get good at passing the blade only once, avoid repeating on the same spots multiple times. If struggling, you might want to consider one of those razors that adjust to your face as you move, or an electric trimmer - avoid the ones that pull the hair before cutting.
A lot of the things that happen to your skin can be caused by bacteria, clogged pores by dead skin, dirty, hair, fabric… Those steps will help you minimize the chances and help your skin recover faster after shaving.
If possible, you should visit a dermatologist for a deeper understanding of your skin, and the care you need.
Also, on a special occasion, treat yourself to one of those old school barbers, with hot/cold towels and all the pampers.
