In 5, Evaluating Data Protection Solutions, we looked at the types of features that are available in many backup software solutions. One feature supported by several of the packages is often called a disaster recovery option. This feature allows systems administrators to recover from a total loss of data on a server (or loss of the server itself) without requiring all the steps necessary for a manual reinstallation. Specifically, disaster recovery options usually include a minimal set of drivers that can be used to access the tape backup or other devices without requiring the installation of the entire OS. This reduces the complete recovery process to the following steps: 1. Boot the system from the disaster recovery media. Usually, this will mean booting from one or more floppy disks, but can also include other bootable media, such as CD-ROM drives. 2. Recover information from the appropriate backup tapes.

A primary requirement when using RDBMSs is consistency. All information must be current up to a certain point in time. If it is not, incorrect or misleading data may be reported. Due to hardware or software failures, it is possible for databases to become corrupt. If there is an internal inconsistency in one or more of the database files on your server, you can attempt to fix them. SQL Server includes several built-in tools for dealing with lost information and corrupted server installations. In this section, we ll look at tools and methods for recovering from these types of failures.

A common problem that occurs in most environments is the improper shutdown of a database server. This might be due to an unexpected loss of power, a hardware failure, or administrator error. If a database server is stopped, the database might contain some transactions that have been written to the transaction log but have not yet been committed to the database itself. This could lead to a database that is inconsistent to a point in time and may result in additional problems. To protect against data corruption, SQL Server 7 automatically performs a recovery operation when the service is started. This operation commits any transactions that appear in the transaction log but have not yet been committed to the database, and rolls back any transactions that cannot be completed. This ensures that the information is consistent and that the database is ready for use by clients and applications. Best of all, the process is automatic when the SQL Server service is started and requires no additional effort by a systems or network administrator.

Recovering System Databases
In addition to user databases and objects that are stored on an installation of SQL Server, the database server itself depends on various system tables for proper operations. Table 7-2 provides a list of the system databases and their functions. In general, if a system database is lost or corrupted, it can be recovered the same way as any other database. We ll cover the specific operations required to restore a database later in this chapter. The tempdb database is a structure that does not require any backups or recovery, because it is automatically re-created whenever the database server is stopped and restarted. If a corruption of the tempdb database occurs, the server should be able to recover automatically (unless, of course, a hardware failure prevents it). Although this covers the loss of most of the system databases, what if the server will not start For example, if the master database is missing or invalid, SQL Server may be unable to start. Let s look at ways to deal with this issue next.
