The disaster recovery plan

The most important thing in brief:

What is a disaster recovery plan?

A Disaster Recovery Plan (DRP) — sometimes also as Disaster and Recovery Plan means — is a structured action plan that ensures that a company can restore its critical systems and data as quickly as possible after an emergency or disaster. In contrast to general business continuity management (BCM), which looks at the entire business operation, the DRP focuses specifically on restoring the IT infrastructure.

Typical threats that require a DRP include:

• Cyber attacks (such as ransomware)
• hardware failures
• natural disasters (floods, fires, power outages)
• Human errors (accidental deletion of important data)

Why is a disaster recovery plan essential?

Economic risks

Without preparatory measures, an IT failure can result in high costs. Studies show that companies can lose tens of thousands of euros per hour of downtime — not to mention damage to their reputation.

Legal and regulatory requirements

In many industries, there are clear legal requirements for data security and reliability. Examples include:

• GDPR: requires technical and organizational measures to protect personal data.
• Basic IT protection (BSI): provides emergency management as an integral part of IT security.
• Industry-specific standards (e.g. KRITIS regulation for critical infrastructures).

customer trust

Companies that remain able to act even in the event of a crisis sustainably strengthen the trust of their customers and business partners.

Practical example: A hospital in a state of emergency

Imagine a hospital that serves hundreds of patients every day. The central IT infrastructure suddenly fails due to a power failure. Electronic patient records are no longer accessible, surgical plans cannot be viewed and even medication dispensing stalls because the systems are blocked. Without quick access to current data, it's not just processes that stall — people's lives are at stake. A Disaster recovery plan would have made the decisive difference here by providing clear steps to restore the systems and thus ensure a secure supply.

How do you create a disaster recovery plan?

Creating a disaster recovery plan is not a one-time act, but a structured process that involves the entire organization and must be maintained on an ongoing basis. Each step builds on the previous one and should be done with consideration and involving all relevant stakeholders. A well-developed DRP takes into account technical, organizational and human factors so that clearly defined processes take effect in an emergency.

Creating a DRP consists of several steps:

1. Risk analysis and prioritization

The first step is to identify the systems and data that are essential for business operations. These include, for example, central databases, email servers, ERP systems or industry-specific applications. It is then analysed which threats are actually relevant — such as cyber attacks, power outages or natural disasters. Scenarios such as human error or service provider failures should also be considered. A structured risk analysis provides clarity here, prioritizes threats and makes it possible to focus on the really critical areas.

2. Definition of RTO and RPO

• Recovery Time Objective (RTO): describes the maximum period of time within which a failed system must be restored so that no serious economic or operational damage occurs. A short RTO means high demands on technical solutions and resources.
• Recovery Point Objective (RPO): determines the maximum amount of data that can be lost, measured in time. For example, an RPO of 30 minutes means that a maximum of half an hour of data can be lost. This directly influences the backup strategy.

3. Development of recovery strategies

Based on the results of risk analysis, RTO and RPO, concrete measures are developed:

• backup strategies: The 3-2-1 rule (three copies, two different media, one external backup) is considered a best practice.
• Redundant systems: By using high-availability solutions or failover clusters, operations can be maintained even in the event of hardware failures.
• cloud solutions: Critical applications and data can also be backed up in cloud environments to enable flexible recovery in the event of a disaster.

4. Documentation and responsibilities

A disaster recovery plan is only effective if it is clearly documented. This includes a detailed description of all processes, checklists for emergencies and a clear distribution of roles. It must be clear who is the contact person, who is allowed to make decisions and how communication works in the event of a crisis.

5. Training and testing

A plan only has an effect if it is regularly tested and the participants are trained. Simulations of failure scenarios help identify weak points and improve processes. Recurring training ensures that all parties involved can act routinely and purposefully in an emergency.

Typical implementation challenges

Many companies fail due to the same stumbling blocks:

• Incomplete inventory: Without an exact overview of systems and dependencies, gaps remain.
• Lack of timeliness: A DRP must be updated regularly.
• Lack of testing: An untested plan is worthless in an emergency.

How Docusnap supports the disaster recovery plan

Here comes Docusnap into the game. The software offers decisive advantages for creating and maintaining a DRP:

Complete IT inventory

Docusnap automatically captures all systems, servers, networks, and applications. This is a current and complete overview before — the basis of every disaster recovery plan.

Dependency analyses

With Docusnap, complex dependencies between systems can be visualized. This prevents critical components in DRP from being overlooked.

Automated documentation

The DRP thrives on precise documentation. Docusnap automatically creates reports, plans, and network cards. This saves time and increases reliability.

Compliance assistance

Docusnap helps to comply with legal requirements such as GDPR or BSI basic protection by creating transparency and facilitating audits.

Benefits at a glance

A disaster recovery plan powered by Docusnap means:

• Identify critical systems faster
• Clearly documented recovery processes
• Higher compliance security
• Lower downtime
• Sustainable protection against economic damage

Best practices for companies

1. Update regularly: Systems are changing, plans must keep pace.
2. Involve employees: Training and clear communication channels are mandatory.
3. Involve external partners: Service providers and suppliers are part of the IT landscape.
4. Perform simulations: Only a tested plan is a secure plan.

conclusion

A Disaster recovery plan is not a luxury, but a necessity for every company — whether SMEs, hospitals or corporations. It not only protects against financial damage, but also against loss of reputation and legal consequences. With a solution such as Docusnap, it is possible to set up a DRP efficiently, completely and in compliance with compliance.

Companies that are prepared secure a decisive competitive advantage: They remain able to act when others sink into chaos.
