IMS Recovery Expert overview

IBM® IMS Recovery Solution Pack for z/OS® IMS Recovery Expert (also referred to as IMS Recovery Expert) helps you to avoid accidental data loss or corruption by providing the fastest, least costly method of backup and recovery.

IMS Recovery Expert provides a fast and easy-to-use implementation of an IMS System Level Backup and recovery methodology. It reduces backup windows by leveraging storage-based fast-replication such that backups of multi-terabyte IMS environments can be performed in seconds or less. It simplifies backup and recovery methodologies by allowing full-system, application, and database-level recoveries to be performed from a common System Level Backup. Consistent backups can be created using "full" or "data-only" System Level Backup options. It provides IMS System Level Backup and recovery support even for complex applications, when data must be backed up, restored, and recovered as a unit. System Level Backups can be taken while the IMS system remains active. In addition, when creating System Level Backups, IMS Recovery Expert invokes storage-based fast-replication facilities through appropriate storage processor APIs. This reduces host CPU and I/O resource utilization and enabling legacy data copy methods to be used while the IMS system is down.

IMS Recovery Expert has integrated, intelligent recovery and disaster recovery managers that analyze recovery assets and establish optimal recovery procedures to minimize recovery time and recovery point objectives. Recovery jobs are tailored specifically to available backup and hardware resources.

• The Intelligent Recovery Manager supplies the ability to perform local recoveries efficiently using all available recovery resources. Restore operations that invoke fast-replication facilities through appropriate storage processor APIs and parallel recovery can significantly reduce recovery time and complexity.
• The Intelligent Disaster Recovery Manager uses local site procedures to prepare for offsite disaster recovery or disaster restart in advance. The information that is acquired allows Intelligent Disaster Recovery Manager to intelligently perform remote site restoration operations and appropriate recovery or restart procedures.
