Parallel backups

In a parallel save operation, one job saves data to multiple tapes devices.

BRMS implements parallel support by utilizing two methods provided by IBM® i. The first method, parallel save/restore support, spreads each object across multiple resources. The second method, multiple-library parallel support, spreads libraries across multiple resources, such that each library is backed up to a single resource. Using these methods, BRMS will attempt to optimize performance and balance resources. Items saved with the second method will have a sequential restore behavior.

Note:
  1. Full backups of *ALLUSR , *IBM, generic library names and other special values are saved using only multiple-library parallel support.
  2. See Performing selected recoveries for information about how to perform recoveries using parallel support.
