Summary
In this chapter, we covered the foundations of transaction logging and database recovery models in order to help you better understand backups. We also covered the various types and categories of backups that can be performed on a database. Understanding backups and performing them properly are essential parts of database maintenance and data recoverability. Without backups, your data can be lost regardless of how much fault tolerance is configured at the hardware or software level. Do not get caught without a good backup, or you may risk losing your job along with the data. Always perform backups and test restoring from them on occasion to verify that you can restore the database and data when necessary.
