The Benefits of FDRINSTANT with IBM RVA or STK ICEBERG with the SNAPSHOT Feature
FDRINSTANT allows you to create a duplicate volume image with Snapshot without changing the volume serial or bringing the duplicate online.
FDR full volume backup, FDRDSF logical data set backup and FDRCOPY logical data set copy use FDRINSTANT technology to read the duplicated volume even while it remains offline with the duplicate volume serial.
A non-disruptive backup or copy can start as soon as the snap is done.
Non-disruptive full volume backup
During this FDR backup of the Snapped volume data sets can be allocated, updated, scratched or go into extents on the primary volume without any effect on the backup of the Snapped volume!
After the backup is complete FDR will optionally release all of the back-end (internal disk) storage associated with the Snapped volume.
Example of how to snap and backup the Snapped volume.
//SNAP EXEC PGM=FDRSNAP
SNAP TYPE=FDR
MOUNT VOL=PRODO1,SNAPUNIT=01FA
//BACKUP EXEC PGM=FDR
//DISK1 DD UNIT=SYSALLDA,VOL=SER=PRODO1,DISP=OLD
//TAPE1 DD DSN=BACKUP.VPRODO1(+1),UNIT=TAPE,DISP=(,CATLG)
//SYSIN DD *
DUMP TYPE=FDR,SNAP=(USE,REL)
NOTE: FDR AUTOMATICALLY FINDS THE OFFLINE SNAPPED VOLUMEMATCHING

FASTCPK with SNAPSHOT
FDRINSTANT enables FASTCPK to use SNAPSHOT to move tracks internally without sending the contents to the host and back again, which results in substantial savings in elapsed time. Since the time to COMPAKT a volume is almost instantaneous, COMPAKTION can be done virtually at any time without interrupting normal processing!

FDRCOPY Datasets with SNAPSHOT in Seconds
FDR InstantBackup enables dataset copy or move requests to automatically use SNAPSHOT to move the tracks if the input and output volumes reside on the same RVA.
