Not a new definition. I’ve used the word “dump” to denote moving data from an active directory to a storage type of medium for many years. When I delete data, I say I “delete” it because that’s irreversible.
In the legal world, when we were doing due diligence reviews for mergers or underwritings we would call it a document dump - meaning dump all the documents on the other side so they had to go through them all to find what they were looking for.
yeah well if im on the jury it means what i think it means...lol...
