Disaster Recovery That Safeguards Your Business Continuity
Replication, backup and rehearsed failover for SAP on-premise, on AWS and on Azure, with recovery targets agreed per system rather than assumed.

average cost of IT downtime per hour during critical outages
Recovery is only as good as the last rehearsal. ETZ Global designs the replication, writes the runbook and tests the failover, so the number that matters is your measured recovery time, not the industry average.
Disaster Recovery
Disaster recovery, designed to two numbers
Disaster recovery for SAP starts with two numbers per system: how much data you can afford to lose (the recovery point objective) and how long you can be down (the recovery time objective). ETZ Global agrees those numbers with the business, then designs the least expensive architecture that meets them: database replication for the systems that need minutes, backup and restore for the ones that can wait a day. The design is tested before it is trusted.
What this covers:
- Recovery point and recovery time agreed per system
- Architecture matched to each system tier
- Written and rehearsed runbooks
- Failover and failback testing
Recovery site in the cloud
Running the recovery site in AWS or Azure removes the need for a second data centre. Replication targets sit in another region as small, low-cost instances until they are needed, then scale up on failover. For on-premise SAP estates this is often the first workload to move to a hyperscaler, because the business case is simple and production stays where it is.
What this covers:
- Second-region or cross-cloud recovery targets
- Low-cost standby, sized up on failover
- Works for on-premise production too
- Network and identity extended to the recovery site
AWS Elastic Disaster Recovery
AWS Elastic Disaster Recovery, the successor to CloudEndure, replicates whole servers block by block into a low-cost staging area in AWS and launches full-size instances only when you fail over. ETZ Global uses it for SAP application servers and non-HANA databases, and pairs it with HANA System Replication for the database tier where recovery has to take minutes.
What this covers:
- Block-level replication of application and database servers
- Low-cost staging, full-size instances on failover
- Point-in-time recovery from replication snapshots
- Combined with HANA System Replication for the database tier
Continuous data replication
Nightly backups leave up to a day of data at risk. Continuous replication, whether HANA System Replication, storage replication or server-level replication, keeps the recovery copy seconds behind production. ETZ Global chooses the layer to replicate at based on the recovery point you need and what the target platform supports.
What this covers:
- HANA System Replication, synchronous or asynchronous
- Storage-level replication
- Server-level block replication
- Replication monitoring and lag alerting
Our DR Methodology
Point-in-time recovery
Replication copies mistakes as faithfully as it copies data. Point-in-time recovery lets you roll a system back to the moment before a bad load, a deleted table or a ransomware encryption started. ETZ Global configures backup and log retention so the recovery window matches your risk, and tests the restore, not just the backup.
What this covers:
- Log-based recovery for HANA and other databases
- Retention matched to the recovery window you need
- Restore tests, not just backup tests
- Isolated recovery for ransomware scenarios
Securing the recovery site
A recovery site is a second copy of your most sensitive data, and it has to be protected like the first. ETZ Global encrypts replication traffic and storage, restricts access with IAM roles and multi-factor authentication, segments the recovery network, and keeps the access and change logs auditors ask for.
What this covers:
- Encryption in transit and at rest
- IAM roles and multi-factor authentication on recovery infrastructure
- Network segmentation of the recovery site
- Access and change logging for audits
SAP HANA data recovery
SAP HANA brings its own recovery tools: system replication between a primary and one or more secondaries, backups to file or to a Backint-certified target, and log backups for point-in-time restores. ETZ Global sets them up, sizes the secondaries for the takeover you need (hot, warm or cold standby), and runs takeover tests on a schedule.
What this covers:
- HANA System Replication setup and monitoring
- Backint backups to AWS or Azure storage
- Log backup and point-in-time restore
- Scheduled takeover tests
Backup and high availability
High availability handles the failures that happen every year, such as a failed host, a network fault or a bad patch, without anyone declaring a disaster. Clustered application services, a HANA secondary in another availability zone and automated failover keep production running while the failed component is repaired. Backups sit underneath for everything else.
What this covers:
- HANA replication across availability zones with automated takeover
- Clustered ASCS/ERS application services
- Backup schedules and retention per system
- Monthly restore verification
When the whole site is lost
When a whole site or region is lost, the runbook takes over: declare the disaster, fail over the database, start the application servers at the recovery site, repoint DNS and interfaces, verify with the business, and later fail back. ETZ Global writes that runbook for your landscape and rehearses it with your team at least once a year, because a plan that has never been run is only a hypothesis.
What this covers:
- Runbook covering database, application, network and interfaces
- Annual or quarterly rehearsal
- Business verification steps
- Planned failback

FAQ Questions
Disaster recovery FAQ
Common questions about recovery objectives, non-disruptive DR testing, hybrid and multi-region recovery, and compliance.
Start a ConversationWhat core disaster recovery services does ETZ Global offer for SAP?
ETZ Global delivers cloud-based disaster recovery, AWS Elastic Disaster Recovery setup, low-cost staging in target regions, continuous data replication, point-in-time recovery, secure backups, automated failover and failback, SAP HANA system replication, and SAP HANA storage-level replication.
How fast can my SAP system recover after a major outage?
Recovery Time Objectives (RTO) and Recovery Point Objectives (RPO) depend on your setup. With AWS Elastic Disaster Recovery and SAP HANA system replication, ETZ Global can configure recovery so that RTO is measured in minutes and RPO is near zero for the systems that need it.
Can I test my disaster recovery setup without disrupting production?
Yes. ETZ Global supports non-disruptive DR drills ("chaos days") using Azure Site Recovery or AWS Elastic Disaster Recovery. These allow simulated failovers in isolated sandboxes, enabling you to validate recovery steps and runbooks without impacting live environments.
Is hybrid or multi-region recovery supported?
Yes. ETZ Global designs high-availability and DR strategies spanning on-premise and hyperscaler environments. Architectures can include cross-region replication, multi-AZ failover for HANA workloads, and controlled failover between cloud and on-premise systems.
How does ETZ Global ensure a secure and compliant disaster recovery environment?
Security is integrated into every step. ETZ Global uses encrypted data replication, enterprise-grade access controls, IAM and MFA, secure network segmentation, and compliance-aligned processes during backup, failover, and recovery phases, ensuring your DR setup meets industry standards.
