You can define storage pools using a wide range of properties to control how data is stored. Each storage pool represents one type of media as specified in the device-class parameter.- Example: Defining storage pools
An engineering department requires a separate storage hierarchy. You want the department's backed-up files to go to a disk storage pool. When that pool fills, you want the files to migrate to a tape storage pool. - Example: Updating storage pools
