FDRDRP reduces the overall disaster recovery time for your z/OS system by enhancing FDRINC’s full-volume reconstruct process.
To achieve optimum usage of high capacity tapes, FDRINC uses “tape stacking” to consolidate each day’s backups (full or incremental) onto as few tapes as possible. However, when running multiple concurrent disk restores, FDRINC would experience heavy tape contention, as multiple volume recovery tasks try to gain concurrent access to the same tape(s).
To overcome this, FDRDRP co-ordinates the concurrent recovery tasks to minimize tape contention and reduce delays caused by excessive (and unnecessary) tape rewinds and dismounts. It achieves this by passing tapes between multiple tasks, and by ensuring that the input tapes are mounted a minimum number of times – often only once.
Savings of up to 80% have been achieved when compared to a standard FDRINC recovery. With FDRDRP you can recover your z/OS system in a much shorter space of time, using your existing FDRINC backups, and without having to change your backup procedures or JCL.
With FDRDRP you can continue to enjoy the benefits of a reduced backup window and minimized application downtime by continuing to deploy FDRINC. And you can continue getting optimum benefit from your high-capacity tapes by “stacking” your FDRINC backups onto fewer tapes, but when you do a Disaster Recovery test (or a real recovery), you can restore your data as quickly as possible with the minimum of tape contention.
