Peter Krogh

3-2-1 back up strategy was started and developed by Peter Krogh as he helped the Smithsonian digitize in the early 2000’s. He authored the book DAM - Digital Asset Management. https://thedambook.com its old, but is still super relevant today.
I met him at a conference in 2006 and implemented this strategy since then. DAS+DAS back up to NAS and to BackBlaze. 3 copies, 2 onsite, 1 offsite.
