When you configure Backup Exec to work with the Backup Exec Migrator, Symantec recommends that you configure two storage devices for staged migration operations. When you consider the devices to use, consider selecting a high performance backup-to-disk folder and a slower performance tape device. By using two devices, archived data can be migrated in two stages.
During the first stage, Backup Exec migrates the data it receives from the Backup Exec Migrator to a backup-to-disk folder on a high performance hard drive. By using a backup-to-disk folder, you can minimize the amount of time it takes to perform the initial migration. During the second migration stage, Backup Exec creates a duplicate job to migrate the archived data from the backup-to-disk folder to a tape device. You can schedule the duplicate job to move the archived data to a tape device at times when media server activity is low.
