Immutable, continuously validated recovery for IBM i, AIX, Linux & PowerVS - reducing RTO from 12 hours to 15 minutes. Proven in regulated environments.

The problem
Traditional backup solutions don’t guarantee clean recovery after ransomware or cyber incidents, leaving organisations exposed to prolonged downtime, regulatory risk, and data loss.
The solution
CopyAssure automates immutable backups and clean-room validation to prove systems can be recovered safely and quickly when it matters most.
The outcome
Reduced recovery times, demonstrable cyber resilience, and confidence that critical systems can be restored after an attack.
Built for mission-critical workloads, CopyAssure helps organisations protect, verify and recover data with confidence after a cyber attack. It delivers automated, continuously tested recovery using secure, immutable backup copies.
By combining cleanroom validation, immutable storage and end-to-end orchestration, CopyAssure ensures your business can recover faster, minimize downtime and maintain operational resilince, even in the face of the most disruptive cyber threats.
Your IBM Power systems run payroll, ERP, supply chain, and core business operations. If ransomware hits and your backup set is compromised, or your recovery process simply fails, you are not looking at hours of downtime. According to IBM's 2025 Cost of a Data Breach Report:
For businesses running IBM i, AIX or Linux workloads, that is 100 days of operational paralysis, manual workarounds, and mounting financial exposure - not because the attack was unstoppable, but because recovery was never properly proven before it was needed.
Traditional backup tools protect your data. They do not guarantee you can get it back cleanly, quickly, and in a state your regulators will accept. CopyAssure was built for the difference between those two things.
Most organisations have never successfully tested a full IBM Power recovery under real conditions. When an incident occurs, that untested assumption becomes an operational crisis.
Recovering IBM i, AIX or Linux environments after an incident is complex. Without continuous validation, your RTO is an estimate - not a commitment you can stand behind.
Untested recovery processes introduce the delays that regulators and boards will scrutinise most.
Corrupted or incomplete data saved into a backup set goes undetected until recovery is attempted. By then, the clean copy you needed may no longer exist.
Recovery under pressure is not the time to improvise. Disparate tools, manual handoffs and undocumented steps introduce the human error that turns a manageable incident into a prolonged outage.
Fast, secure, and automated recovery for IBM i, AIX, and Linux workloads in PowerVS. CopyAssure delivers clean, verified restore points using immutable, air-gapped backups.

Resilient, automated cyber recovery for IBM Power and PowerVS—built for confidence, compliance, and continuity.
Snapshots and clones are automatically validated to meet strict RPO and RTO objectives- no manual effort required.
Tamper-proof, ransomware-resistant backups isolated from production systems for maximum data security.
Every recovery point is verified in a secure cleanroom through system, app, and data-level testing.
End-to-end automation eliminates manual steps, reduces recovery errors, and ensures consistent, scalable execution.
Built to support Identify, Protect, Detect, Respond, and Recover - strengthening resilience and audit readiness.
Proven, tested restore points give you full assurance that recovery will succeed when it matters most.
Copy Assure is Celerity’s automated cyber-resilience and recovery solution designed specifically for IBM Power, IBM i, AIX, Linux and PowerVS environments.
It creates isolated, immutable backup copies and continuously tests recoverability to ensure organisations can restore systems quickly in the event of an outage.
CopyAssure takes secure, scheduled snapshots of IBM Power, IBM i, AIX and Linux workloads, isolates them from production, applies immutability and verifies each restore point in a clean test environment.
Unlike standard backups, CopyAssure combines immutable backups, air-gapped snapshot protection, cleanroom validation, and regular recovery testing. This ensures backup copies are not only protected but proven to be recoverable for compliance purposes.
This assured, rapid recovery reduces downtime and keeps businesses running smoothly.
CopyAssure uses automated workflows and validated recovery points to enable faster and more predictable RTOs and RPOs.
For example, one of our CopyAssure clients saw:
Any organisation running critical workloads on IBM Power (IBM i, AIX, or Linux) needs CopyAssure. This is especially true for those that must guarantee clean, proven recoverability from a compliance perspective. This includes sectors like:
In short, any industry where downtime, data corruption, or failed restores can cause major operational, financial, or compliance impacts.
Lock in unshakeable cyber resilience: 24/7 monitoring, instant response, and top‑tier data protection combine to keep your data safe and recoverable, while keeping downtime to a minimum.
Guarantee protection and continuous access to data with managed backup. Deploy seamless data protection solutions on premises, off-premises, or in the cloud.
