Of all the things our company does badly, I can actually say backups are pretty close to perfect! They are monitored closely for issues since they run all day every day and are tested quarterly to make sure they work. They also have to since it's part of the yearly audit. Also, they have saved us numerous times from little things like people deleting stuff to full system restores due to bad changes. Thankfully, we never needed them due to our company being compromised... and really hope we never do.
