The agony of NFS for 25+ years of my life! Then and now. ClearCase and Kubernetes
My first experiences with NFS (Network File System) started in 1989. My first term at university, a set of vax machines running BSD Unix, some vt220 terminals, and ‘rn’. My first understanding of NFS came a few years later. ClearCase. I was working at HP, the year was 1992. Most of us on the team…
Hack or Genius: cloud backup revisited
