A triage system is essential to determining your archival strategy! We can produce information faster than we can produce information storage systems, so we need to be discerning! Random gibberish is less valuable than a screenshot you took in 2015, and that screenshot from a decade ago is probably less valuable than your tax returns or your treatise on the meaning of life! If it's worth keeping, it's worth putting some time into every few years to make sure it's copied somewhere.
