Working in conjunction with hardware replication features such as EMC TimeFinder (including CLONE/Snap), Hitachi ShadowImage and IBM FlashCopy, FDRINSTANT can reduce your backup window, and virtually eliminate application downtime commonly associated with taking regular backups.
Although their methods of implementation differ, all of the supported hardware replication features listed above share the same common ability to create duplicate volumes, while your applications (CICS, TSO, Batch, etc.) continue to use the real data on the original online volumes. FDRINSTANT allows you to take a backup directly from those offline volumes.
FDRINSTANT does not require the duplicate volume be brought online; it can access it across the channel while the volume remains offline to z/OS, thus eliminating problems with duplicate volsers and the potential for VTOC/VVDS and catalog discrepancies.
FDRINSTANT Deployment
FDRINSTANT is a cost-option to the FDR DASD Management Family, and can be deployed with the following modules:
- FDRINC (Managed volume incremental backup)
- FDR (Manual and ad-hoc, full Volume and dataset backup)
- FDRCOPY (Dataset copy and move)
Faster, Compromise-Free Restores
Using FDRINSTANT to create your FDR or FDRINC backups does not introduce a compromise when it comes to restoring data sets or volumes. All of the same restore facilities that are available with “conventional” FDR and FDRINC backups are available with the backups you create with FDRINSTANT.
Consistent Backup
Consistent point-in-time operations, available in some hardware replication features, allow the replication of multiple disks at a single consistent point-in-time. This ensures their I/O integrity by preventing applications such as DB2 from issuing dependent writes during the split/snap process. Once the group of offline duplicate volumes has been detached at a consistent point, FDRINSTANT can then take a “consistent backup” of the data from that group of offline volumes.
