It INFURIATES me how many companies will spend money on backups, but not ever test that their backups restore or allow for continued functionality afterwards.
At one company, I banged this drum for years, and one day we had a situation where someone “accidentally” deleted all the media from a client website. I had to dig through several backups and rebuild from beta, which annoyed me endlessly, but I dropped the “I fucking told you so” several times, and hinted that our “restore scripts weren’t working as intended” to the client. It took me a full day to do what should have taken maybe 1-2 hours at most…
