Backup and Restore Strategies

The backup strategy you choose has a direct impact on the method you use to restore Exchange. If you create full backups on a daily basis, you need only one tape to restore Exchange. This backup method minimizes the volume of data and the time it takes to restore Exchange.

Before choosing a backup strategy, it is important to understand how Exchange stores information. Exchange 2000 allows you to create multiple smaller databases on a single server. However, to reduce the overhead of multiple sets of transaction log files, Exchange 2000 uses storage groups. In this case, only one set of transaction log files is required for an entire storage group.

This diagram illustrates the architecture of Information Store. Exchange supports 20 databases per server, with a maximum of 5 databases per storage group. Although each instance of a database runs under the same Information Store process, you can mount or dismount individual databases dynamically. The advantage is that you can restore an individual database from a backup while other database instances service client requests.
