Performing System Level Backups on Hitachi storage systems

IMS Recovery Expert can make backups of IMS subsystems on Hitachi storage systems in two ways.

Choose the backup method that is applicable to the storage subsystem:

• If the storage subsystem has the Hitachi ShadowImage In-System Replication software, and you want IMS Recovery Expert to use ShadowImage commands when backing up the system, set the PARMLIB parameter SHADOW-IMAGE to Y. Then, create and run FlashCopy® backup profiles.

  IMS Recovery Expert will detect when source and target volumes are on Hitachi hardware. If so, IMS Recovery Expert will perform native ShadowImage commands to copy the volumes instead of using FlashCopy commands.

  Note: If you plan to restore individual objects from a System Level Backup made using ShadowImage commands, fast replication cannot be used to restore the objects.
• If the storage subsystem has the optional Hitachi ShadowImage Compatible Mirroring for IBM® FlashCopy installed, when you create and submit FlashCopy backup profiles,IMS Recovery Expert will issue FlashCopy commands to create the System Level Backup.
