Around 1999, I worked for a dotcom startup. One day, a fellow developer had to delete some data from our SQL database. Unfortunately, he used recursive delete which cased pretty much all data to be deleted on that server including forum posts, users, etc. We did have backups... a bit stale, a few weeks old. We lost several weeks of new users, forum entries, etc of our social plattform by not having a proper backup plan and using some stupid GUI for SQL deletion (which had recursive enabled by default...).
