There are three types of loss: destruction, discoverability, and synthesis. Destruction is the one most people think of. The last tape is destroyed, or someone nukes everything in S3. Policies normally save this from happening, bit not always. (I note that lawyers are pretty good at saving things because of discovery, so perhaps corporations should sue themselves more often /s) Discoverability is when the data is there, but noone knows where it is. This is your classic corpo Sharepoint/teams/slack problem. There was a chat, once, with some shared files, from their onedrive, but the last person who remembered where was laid off a year ago and...well, that data is effectively lost. I dont think we have great solutions here except writing even more things down and hoping that everyone follows rules like keeping all files in one place The last case is where the data is located, but noone can vouch for it any more. Internal wiki pages are notorious here. People post about, say, some sharp edge they uncovered, and the page sits there for all eternity. You discover it years later. Can you trust it? Is there anyone who knows why the page still exists? It blocks the synthesis of what you know with what the author knew.
