While this article is focused on 2005 syntax, most of the concepts are applicable to 2000. This is a huge topic. At best, I’m going to scratch the surface and give you enough information so you won’t start crying again.

Recovery ModelsIn order to begin working on your sql server backups, the business needs define a database recovery model. In essence, a recovery model defines what you’re going to do with the transaction log data. There are three recovery models: Full, Simple and Bulk Logged. These are pretty easy to define:
- Simple – in simple recovery mode, the transaction log is not backed up so you can only recover to the most recent full or differential backup.
- Full – in full recovery mode you backup the database and the transaction log so that you can recover the database to any point in time.
- Bulk Logged – in bulk logged mode, most transactions are stored in the transaction log, but some bulk operations such as bulk loads or index creation are not logged.
