Using VBACKUP to Process Point-in-time DASD Volume Images

VBACKUP allows a backup of an offline DASD device containing a previously created point-in-time image of an online DASD volume. While VBACKUP is processing the offline DASD volume, the online volume from which the image was taken is available for normal use and updates. Since the offline image is actually read, changes to the online volume will have no effect on VBACKUP. VBACKUP supports point-in-time images created by, among others, IBM RVA with SNAPSHOT COPY feature, IBM 2105 with FLASHCOPY feature, StorageTek ICEBERG/SVA with SNAPSHOT COPY feature, EMC Timefinder BCV Volumes, and HDS ShadowImage feature. The ARCHVOLs created by VBACKUP while processing offline DASD volumes are supported by the VRECOVER command.
