Cascade configurations
When the backup is of an SQL Server database, Application Agent can handle the backup to a
secondary volume at a remote destination. The backup configuration in this case is called a cascade
configuration because backup configuration has multiple hierarchies. For data backup and restoration
in a cascade configuration, use user scripts. However, in a cascade configuration consisting of Business
Copy volumes only, user script cannot be used.
The following is an example of a cascade configuration consisting of Business Copy volumes and
Continuous Access Software volumes when the backup is of an SQL Server database.
