To improve backup speed, you can use the Database manager GUI to back up data to multiple backup media in parallel. For this purpose you define a group of parallel media under a single medium name. When you restore, you can import the data from this type of backup in parallel.
You have connected the database instance to the DBM Server.
Choose one of the following procedures:
·
Select the required
database instance in the list of database
instances.
Choose Instance ® Backup ® Backup Medium.
Choose Actions ® New Parallel Medium.
·
Backup Wizard
Choose New
Parallel Medium in the
Media for
Backup window.
Choose General and enter the following information:
