Database Backup & Recovery for IMS

Mainstar Database Backup and Recovery for IMS™ (DBR for IMS™) is a storage-aware backup and recovery solution that integrates storage processor fast-replication facilities with IMS backup and recovery operations to allow instantaneous backups, reduce recovery time and simplify disaster recovery procedures while using less CPU, I/O, and storage resources.

• Perform IMS system level backups instantaneously with no impact to the business
• Fast restore and parallel recovery reduces recovery time and complexity
• Transforms disaster recovery into a disaster restart process reducing RTO
• Significantly reduce costs by using less CPU and I/O resources
• Reduce storage costs by utilizing one backup for multiple purposes
• Eliminate backup windows and extend batch processing windows
• Achieve successful recoveries - every time - by performing backup validation
• Managed recovery processes provide IMS recovery tool integration
• Uses a sophisticated ISPF interface and meta-data repository to manage backup, recovery, and disaster recovery processing
• Perform IMS system cloning operations from a system level backup

DBR for IMS facilitates an IMS system level backup (SLB) methodology. It coordinates IMS system and storage-based fast-replication facilities to backup IMS systems fast and effectively without using host CPU and I/O resources. DBR for IMS generated system level backups can be used for IMS system recovery, application recovery, database recovery, and for IMS disaster recovery purposes. Using an effective DBR for IMS system level backup methodology allows IMS system level backups to be used for multiple recovery purposes saving CPU, I/O, and storage resources required to create multiple backups for specific uses.

DBR for IMS Features Summary

• Create instant point-in-time IMS system level backups without affecting application availability.
• “Storage aware” database utilities use storage processor fast-replication to copy the data.
• Provide support for IBM, EMC, and HDS storage systems and fast replication processes.
• Specialized meta-data repository used to correlate IMS storage volumes with backup volumes and recovery information.
• Creates a system level backup that can be used for system recovery, application recovery, database recovery, or disaster recovery using disaster restart procedures.
• Discovers IMS systems and provides configuration advice for data set layouts.
• Defines backup type, fast replication usage, volume mappings, and retention period options needed to perform and record a system level backup.
• Automatically validates IMS backups are complete and can be used for recovery.
• Integrates IMS recovery tools into a DBR for IMS recovery management process.
• Provides the ability to backup and restore a subset of the IMS system.
• Archives disk-based backups to tape or disk, including remote disk. Archive copies can be used for subsequent recoveries.
• Provide effective restore of an IMS system and recovers the system in parallel to help reduce recovery time and reduce application down time
• Performs application and database level recovery from a system backup.
• Transforms traditional IMS disaster recovery procedures into an IMS tape-based disaster restart process.
• Integrates with Mainstar Clone and Rename for IMS (ICR) to allow IMS system cloning from an IMS system backup.
