Backing up and restoring in a cascade configuration
This section provides an example of backing up and restoring in a system configuration that consists
of a database server and a backup server in a cascade configuration. The explanations in this section
use operation examples for Exchange Server 2007.
The following examples are provided:
• Performing backups using VSS concurrently at both the local and remote sites (backup data is
created on secondary volumes). In this example, the backup data on the secondary volumes is
then backed up to a tape device at both the local and remote sites.
• Restoring data using the backup data on the tape device at the local site.
• Restoring data using the backup data on the tape device at the remote site.
The examples in this section assume the system configuration shown in the following figure.
