Enhanced z/OS Disaster Recovery for ABR (FDRINC) DASD Volume Restores
FDRDRP reduces the overall disaster recovery time for your z/OS system by enhancing the ABR (FDRINC) full-volume reconstruct process.
FDRDRP co-ordinates multiple FDRINC volume restore tasks in order to minimize tape contention and reduce delays caused by excessive (and unnecessary) tape rewinds and dismounts.
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.
Why do I Need FDRDRP?
If you’re creating full and incremental backups with FDRINC, the likelihood is that you are creating lots of individual backup files each day.
To achieve optimum usage of each backup tape, you’re probably using “tape stacking” to put those individual FDRINC backups onto one (or maybe just a handful) of high capacity tapes.
In the simplified example below, the FULL backups of disks PROD01, PROD02 and PROD03 have all been written onto one tape (volser 111111), and all of the Monday incrementals for the same disks have been written onto another tape (volser 222222).
Unfortunately, when running multiple concurrent disk restores during a Disaster Recovery (test or real), FDRINC would experience heavy tape contention, as multiple volume recovery tasks for volumes PROD01, PROD02 and PROD03 all fight to gain concurrent access to the same physical tape(s).
See the TECH page for a more detailed description on how FDRDRP addresses the problem.
No Need To Change Your Backup Procedures
The key benefit of FDRDRP is that it does not require you to make any changes to your existing FDRINC backup procedures. This means you can:
Other Disaster Recovery Tools
In addition to FDRDRP described above, the FDR Storage Management System also includes a range of other tools that can help you prepare for and implement your Disaster Recovery strategy.
