In a multi-robot environment, configure all of the robots as backup robots and configure one of the backup robots as a Vault robot also. (One of the robots functions as both a backup robot and a Vault robot.) Configure one vault for the Vault robot, and in that vault configure one profile for each of the backup robots. In each profile, specify the backup robot in the Source Volume Group field of the Choose Backups tab and specify a destination storage unit that is in the Vault robot.
For example, if you have three robots that each have four drives, configure the three profiles as follows:
In the profile for robot one (a backup robot only), specify the volume group in robot one as the Source Volume Group, specify four read drives, and specify a destination storage unit in robot three (robot three is the Vault robot). Images in robot one are read by four drives and written to four drives in robot three. Four duplication jobs run simultaneously.
In the profile for robot two (a backup robot only), specify the volume group in robot two as the Source Volume Group, specify four read drives, and specify a destination storage unit in robot three. Images in robot two are read by four drives and written to four drives in robot three. Four duplication jobs run simultaneously.
In the profile for robot three (a backup and Vault robot), specify the volume group in robot three as the Source Volume Group, specify two read drives, and specify a destination storage unit in robot three. Images in robot three are read by two drives and written to two drives. Two duplication jobs run simultaneously.
All images are duplicated to robot three and ejected from robot three.
This method works well with backup policies that use Any Available storage unit. Using Any Available storage unit in your backup policies sends backup images to media in any storage unit available. This configuration selects backup images on all the robots and duplicates them to the Vault robot.
