Disaster Recovery & Backup as the Foundation for Resilient OT Systems

The NIS2 Directive (Network and Information Security Directive 2) of the European Union has been transposed into national law as of October 2024.
It requires affected organizations to implement verifiable cybersecurity measures not only in IT, but explicitly also in manufacturing environments and OT systems.

Whether a company falls under the scope of NIS2 can be verified for Germany using the official

BSI relevance check for the NIS2 Directive
.

For companies in other EU Member States, the assessment must be carried out via the respective national authority.

The focus is not only on preventing cyberattacks, but above all on the ability to restore production systems quickly and in a controlled manner after a security incident.

What Is NIS2 and Who Is Affected?

The NIS2 Directive applies to organizations with at least 50 employees or an annual turnover of 10 million euros,
provided they operate in critical or important sectors – including many manufacturing and industrial companies.

• verifiable technical and organizational measures
• resilience and recoverability instead of pure prevention
• clearly defined responsibilities up to executive management level

For manufacturing companies, this means:
not only preventing incidents, but being able to resume operations quickly after disruptions.

Why NIS2 Particularly Affects the Shopfloor

While IT environments often have established security and backup processes, OT environments are typically grown over time.
Common gaps include:

• lack of full transparency across OT systems
• missing or outdated configuration documentation
• unverified emergency and restart procedures

As a result, key NIS2 requirements in OT environments include:

• full visibility of systems and configurations
• controlled and traceable access
• tamper‑proof, audit‑ready documentation
• reproducible system and configuration states
• verifiable evidence for audits

Disaster recovery and backup management therefore form a central pillar of business continuity.

Backup & Disaster Recovery in Manufacturing Environments

• regular backups of PLCs, HMIs and SCADA configurations
• defined restart procedures for machines, lines and entire plants
• OT‑specific disaster recovery concepts
• restore processes tested under realistic conditions

Without functioning backups, production may be interrupted for days in the event of system failures or ransomware attacks.

Incident Response, Risk Analysis and Recovery

NIS2 requires structured processes for handling security incidents.
In OT environments, incident response primarily means:

• isolating affected systems
• limiting damage
• restoring systems reproducibly from backups

Backup strategies are an integral part of an overall risk analysis, identifying critical assets,
single points of failure and acceptable downtime.
A backup is only effective if the restore process is tested regularly.

How the eguide4DATA Software Supports NIS2 Requirements

eguide4DATA is a software solution designed to address key NIS2 requirements in OT environments through structured,
audit‑ready processes.

Automated Backup & Versioning

eguide4DATA automatically and reliably backs up OT systems in a tamper‑proof manner.
Every configuration state is reproducible, including a complete and traceable version history.

Role‑Based Access Control

Granular user roles, multi‑factor authentication, Active Directory integration and SSL encryption ensure controlled and documented access
in line with the least‑privilege principle.

Audit Trails & Evidence Documentation

All security‑relevant actions – backups, configuration changes and access events – are logged in a complete and immutable audit trail.
This makes audits predictable instead of reactive.

GxP Workflow for Regulated Industries

An optional GxP module extends backup and versioning with a structured approval workflow based on the four‑eyes principle,
particularly relevant for pharmaceutical, medical device and food manufacturing.

Pragmatic NIS2 Implementation Roadmap

1. assessment of OT systems and current processes
2. pilot implementation (e.g. one line or one plant)
3. definition of backup cycles, roles and alerting rules
4. rollout to additional sites
5. generation of audit reports at the push of a button

Conclusion: NIS2 Is Not Achievable Without Reliable Recovery

• tested restore scenarios for critical production assets
• tamper‑proof and traceable backups
• recovery times aligned with production requirements – minutes instead of days
