To improve backup speed, you can back up data to multiple backup media in parallel. To do this, define a group of parallel backup media under a single medium name. A backup made to multiple media in parallel must have the name of the group of parallel media assigned to it. When you restore data, you can import the data from this type of backup in parallel.
You can change backup media interactively with the Database Manager GUI or the Backup Wizard.
You have made the connection between the database instance and the DBM Server.
