Well, the biggest problem I faced at my last job was due to us restructuring our customer database and information, we kept on losing data that was recorded maybe like two or three hours ago. So during my production, I would continuously have a backup hard drive, which I would then copy not only our database information onto our own database, but onto my hard drive. So we made sure we had a complete copy of the day's current data available at all times, and available to be backed up onto the main server.
