alt Hacker NewsAgreed, if you haven't tested your backups recently (daily, automatic best), you don't have backups. Several of my clients (CTO Coaching) had problems in the past because they restored backups and where finding they were not complete (for various reasons).
daily test restore is infeasible for anything but toy projects. You should periodically test your restore procedures, but its incredibly costly and time consuming for sizeable platforms. Its just not that easy to restore a 10+TB backup for example, and thats a _tiny_ backup size for a b2c product.
they can easily go into the hundreds of TB, depending on your platform.
and i might add: i vividly remember gitlabs article how they have had automated backups and test restores for years, but when they actually needed them... it turned out some data wasn't part of it after all. just because youre testing your restore procedure doesnt mean you've actually accomplished anything.
