Duplex Copies

Duplexing provides a second copy of the data sets processed by that group. This provides 100 percent redundancy for media and Disaster Recovery.

Duplex copies can also be used with a different system, such as an off-site location, using another copy of CA Vtape.

We recommend the use of Duplex copies when the Primary copy is a high-capacity cartridge.

Note: Duplex copies are automatically accessed for Recalls if the primary copy is not cataloged or after the execution of the SET RECALL=DUPLEX console command.
