Disaster Recovery
Disaster Recovery & DRaaS Solutions for IBM i
At DataTech Computer, we understand that unplanned downtime is not just an IT issue; it is a critical business threat. A comprehensive
Protecting your mission-critical IBM Power Systems, AS/400, and iSeries infrastructure requires more than just periodic manual backups. It requires a resilient, multi-tiered strategy tailored to modern threats.
The Shift to Disaster Recovery as a Service (DRaaS)
Historically, owning and managing a secondary data center for disaster recovery required a massive capital investment in infrastructure, facilities, and maintenance.
Key benefits of transitioning to a DRaaS model include:
-
Faster Recovery Times: When disaster strikes, DRaaS minimizes your downtime by allowing an instant failover to a redundant system hosted offsite, drastically shortening your Recovery Time Objectives (RTOs).
-
Reduced Costs: Adopting a pay-as-you-go or subscription model effectively eliminates the heavy upfront capital and labor costs needed to maintain idle alternative sites and hardware.
-
Greater Scalability: Cloud-based functionality allows you to tailor your storage and replication needs as your enterprise grows, freeing up your internal IT staff to focus on core business functions.
-
Improved Compliance: Faster recovery limits data loss and downtime, significantly reducing the financial punishments and compliance violations associated with data breaches in heavily regulated sectors.
Essential IBM i Backup and Recovery Strategies
Ensuring continuous data protection on IBM i requires a highly structured approach. To safeguard your environment effectively, your IT strategy should include these core components:
-
Implement a Multi-Tier Backup Plan: Combine daily incremental backups for recent changes with weekly library backups (SAVLIB) for critical applications, and monthly full system backups (SAVSYS) to capture your operating system, licensed internal code, and configuration.
-
Automate with BRMS: Utilizing Backup, Recovery & Media Services (BRMS) simplifies your workload by automating recurring backup schedules, media tracking, and complex recovery operations.
-
Establish HA and Real-Time Replication: For mission-critical workloads, High Availability (HA) solutions provide real-time, journal-based replication to a secondary system.
This ensures a seamless failover with minimal latency and preserves your Recovery Point Objectives (RPO). -
Test Your Backups Regularly: A backup is only as good as its restore. Perform periodic restoration tests to verify the integrity of your data and ensure your team is prepared for a smooth recovery process.
Modernizing Disaster Recovery Options for IBM i
The landscape for IBM i (iSeries/AS400) disaster recovery is continuously evolving. Industry experts highlight several critical shifts that legacy users must consider when modernizing their IT infrastructure:
-
Virtual Tape Libraries (VTL): Physical tape drives and manual backups are rapidly being replaced. VTLs offer faster, tapeless, and often more affordable local backup capabilities while seamlessly integrating with cloud storage for offline, offsite protection.
-
IaaS and Cloud Hosting: As aging legacy hardware becomes more expensive to support and replacement parts grow scarce, migrating to Infrastructure as a Service (IaaS) provides a secure, reliable, and cost-effective alternative to maintaining on-premise hardware.
-
Data-at-Rest Encryption & Endpoint Security: Securing your backups is paramount. Relying on outdated security protocols leaves systems vulnerable to modern ransomware. Active user involvement is required to implement robust data-at-rest encryption and enforce strict endpoint security to lock out unauthorized access.
