To understand complex Exchange 2000 backup and restore processes, it is important to gain an understanding of Exchange 2000 database technology.
Understanding transaction logging and how database, checkpoint, and log files relate to each other in previous versions of Exchange enhances familiarity with Exchange 2000 database technology.

Note: Although familiarity with backup and restore procedures in previous versions of Exchange provides a good foundation, it is crucial to become familiar with the procedures in Exchange 2000. For example, utilities that are available in previous versions of Exchange (such as ESEUTIL or ISINTEG) may require different syntax when run against Exchange 2000 databases.

It is important to be familiar with the following Exchange 2000 technologies as they relate to disaster recovery:

• Storage groups and databases
• Transaction logs
• Checkpoint files
• Circular logging
• Database recovery considerations
