Application Resilience When Infrastructure Fails‍

Disaster Recovery

We replicate critical workloads, define recovery objectives, and test failover annually ensuring applications recover when infrastructure fails.

The Challenge

Infrastructure fails. The question is: how quickly do applications recover?

Documented DR plans without testing don't meet audit or regulatory requirements.

Disaster Recovery provides:

  • Workload replication to secondary infrastructure
  • Documented RTO (Recovery Time Objective: how quickly systems must be operational) and RPO (Recovery Point Objective: how much data can be lost) per workload group
  • Automated or documented failover procedures
  • Annual testing with minimal production impact
  • Audit-ready documentation

‍

How It Works

We provide tested application resilience:

1. Define recovery objectives (RTO and RPO per workload group)

2. Replicate to secondary infrastructure (private cloud, public cloud, or owned facilities)

3. Implement failover procedures (automated with RecoverPoint where deployed, or documented procedures)

4. Test annually (minimal production impact)

5. Document results (evidence for auditors)

‍

What You Get:

• Application-level resilience (not just data backup)

• Documented and tested recovery times

• Evidence for regulators and auditors

• Business continuity assurance

‍

Who Is This For?

Organisations that need:

• Board questions about ransomware readiness

• Cyber insurance requiring recovery validation

• Regulated environments demanding resilience proof

• Critical infrastructure that can't tolerate extended downtime

‍

‍

Common Starting Points:

• Audit requiring DR testing proof

• Regulator questioning resilience

• Board mandate for business continuity

• Critical applications with no DR

‍

‍

Where This Leads:

Disaster recovery is where organisations often start when audits or regulators demand evidence.

Organisations typically need:

• Backup & Recovery: Data protection

• Cyber Recovery: Validated restore from attacks

• Disaster Recovery: Application resilience (you're here)

All three are part of Recovery Confidence. one of four outcomes you get with Adaptive Cloud.

Why Synapse?

Proven disaster recovery for critical environments:

• DR storage and replication

• Documented RTOs and evidence

• Audit support and compliance documentation

‍

Trusted by:

• Critical national infrastructure

• Healthcare organisations

• Regulated financial services

Things you need to know

Common Quetions

‍

What's an RTO?

Recovery Time Objective: how quickly must this application be operational after failure?

Typical RTO targets by system criticality:

Critical systems: 4-8 hours

(Requires Dell RecoverPoint automation, proper infrastructure, annual testing to validate)

Business-critical systems: 8-24 hours

(Can use replication or backup-based recovery)

Standard workloads: 24-48 hours

(Typically backup-based recovery)

Important: Actual RTO depends on:

• Technology platform (RecoverPoint vs vSphere vs backup)

• Workload complexity

• Data volume

• Infrastructure (private vs public cloud)

• Whether automation is available

Do I need DR if I have backup?

Backup restores data. DR restores applications. Both required for complete resilience. See Recovery Confidence for complete explanation.

How often should DR be tested?

Annual failover testing (minimum recommendation)

Annual full DR exercise with all stakeholders

Why annual:

• Validates technology still works

• Trains staff on procedures

• Identifies configuration drift

• Provides evidence for auditors

Testing conducted with minimal production disruption (though some impact possible depending on network configuration).

‍

Is there production impact during testing?

Typically minimal to no impact.

However: If Layer 3 networking is used instead of Layer 2 circuits, there may be some disruption during testing.

Our approach:

• Test during agreed maintenance windows

• Monitor production closely

• Implement safeguards to minimise impact

• Document any impact for future planning

‍

What's automated failover?

With Dell RecoverPoint:

• Automated failover procedures

• Reduces manual steps

• Achieves faster RTOs (4-8 hours possible)

Without automation:

• Documented manual procedures

• Step-by-step runbooks

• More time required

• Typical RTOs 8-24 hours

Automation availability depends on your infrastructure and technology choices. Works with private cloud infrastructure using Dell technologies.

‍

Where does DR infrastructure run?

Options include:

• Secondary private cloud site

• Public cloud (Azure, AWS)

• Hybrid (private to public or vice versa)

• Owned Crown Dependency data centres

Choice depends on your primary infrastructure, sovereignty requirements, and recovery objectives. DR storage and replication configured appropriately for each option.
