Obviously, it is worth sharing not only your success stories but also your failures in order to anticipate the future better.
During the fucked up session, I had a presentation describing a story where the problem arose over time, and whether the fan would scatter the waste was not a question of if but when.
Crackers literally had attacked a website, and as it turned out, no one had a safe copy, and only defaced backups were available.
DevOps often say that we divide people into those who make backups and those who will make backups.
From the summary of my presentation, it seems worth adding another group of people – those who check whether restoring a backup is successful.
