Summary – Remember that an outage can be costly in both revenue and trust, and that a simple backup without a DRP leaves your business exposed to uncontrolled data loss and recovery delays. By combining three copies (production, local storage, off-site), targeted RTO/RPO, a tailored DRP with roles, failover procedures, and regular tests, and automated open-source components (Restic, Ansible, CI/CD, encryption), you reduce failure points, avoid vendor lock-in, and control costs.
Solution: conduct a business audit to calibrate RTO/RPO, deploy a minimal 3-2-1 and iterative DRP foundation, then refine with quarterly tests and flexible modules for fast, reliable recovery.
For decision‑makers and technology leaders, a 3‑2‑1 backup means keeping three copies of your data on two different media, with one copy off‑site. A Disaster Recovery Plan (DRP) defines the procedures and responsibilities to restore your service after an incident. Together, these two pillars ensure business continuity and minimize the risk of prolonged downtime.
The 3‑2‑1 principles combined with a DRP form an essential duo for any organization committed to resilience and maximized ROI in security and availability.
1. Core Principles of 3‑2‑1 Backup and Disaster Recovery
Summary: The 3‑2‑1 rule secures your data; the DRP prepares you to restore it.
A 3‑2‑1 backup strategy relies on three distinct copies of your data: the primary production copy, a second local backup (NAS, hard drive), and a third off‑site copy (cloud or managed service). This setup limits single points of failure and reduces the chance of total data loss in the event of a physical disaster or cyberattack. Adopting this approach requires carefully assessing your Recovery Time Objective (RTO) and Recovery Point Objective (RPO) to select the right open‑source technologies and avoid vendor lock‑in.
Disaster recovery, or your DRP, complements the 3‑2‑1 backup. While backups guarantee data integrity, the DRP formalizes the steps to reinstate your critical services. It specifies roles, failover processes, and standby environments. It’s best to adopt a flexible plan—there is no one‑size‑fits‑all solution—that aligns with your business context and leverages existing components, whether banking systems, e‑commerce platforms, or ERP.
To stay agile, Edana’s approach combines bespoke development with proven open‑source components (Node.js, Linux, PostgreSQL…). This mix minimizes technical debt and optimizes costs while ensuring scalability and security. Every environment is unique, which is why we architect your ecosystem with a flexible methodology focused on digital transformation and, when relevant, eco‑responsibility.
2. Building a Tailored Disaster Recovery Plan for Your Organization
Summary: A custom DRP guides restoration and ensures business continuity.
An effective DRP begins with an audit of your business processes and critical scopes. This involves identifying strategic applications, their dependencies, and required service levels. In collaboration with your ops, security, and IT teams, our experts design a recovery plan that combines standby environments, automated failover procedures, and regular testing. The goal is to minimize downtime (RTO) and acceptable data loss (RPO).
Every context has its own requirements, so we customize each DRP accordingly. For example, for a Swiss bank, we built a managed standby platform with encrypted backups via Infomaniak and TypeScript automation scripts that handle failover in under five minutes. We then established quarterly test cycles to validate full service restoration and fine‑tune procedures based on feedback. This pragmatic approach not only significantly reduced RTO but also boosted operational teams’ confidence in their infrastructure’s resilience.
At Edana, we favor an iterative process: deploy a minimum viable recovery framework first, then enhance the DRP based on real‑world tests. This semi‑custom methodology keeps technical debt in check and integrates seamlessly with your development cycles, whether agile or waterfall. You achieve controlled recovery aligned with your business goals and budget.

3. Selecting Open‑Source Technologies for Your Backup Strategy
Summary: Open source cuts costs and prevents vendor lock‑in.
When it comes to backup strategy, open‑source solutions deliver flexibility and transparency. Unlike proprietary offerings, they free you from costly licenses and long‑term commitments. Some of the most popular building blocks include:
- BorgBackup for deduplication and encryption
- Restic for ease of use and multi‑backend support
- Duplicity for incremental archiving
These tools integrate naturally with orchestration frameworks (Ansible, Terraform) to automate snapshot creation, off‑site transfers, and integrity checks. Embedding them in a CI/CD pipeline validates backups with every deployment, reinforcing your confidence in the restore process.
Edana’s approach? Depending on your needs, we integrate these tools, develop custom extensions, or mix open‑source components with bespoke code. For instance, a TypeScript hook can extend Restic to trigger alerts in Slack or Jira upon failure. This tailored ecosystem delivers agility and real‑time visibility while respecting your governance and sustainability requirements.
By choosing these solutions, you benefit from active communities and regular updates—crucial for security. We also document each component in Confluence, ensuring long‑term maintainability and internal skill growth.
4. Embedding 3‑2‑1 Backup in a Scalable, Secure Architecture
Summary: Your architecture must grow with your business and protect your data.
A 3‑2‑1 backup is most effective when it’s part of a system designed to evolve with your needs. Rather than imposing an off‑the‑shelf solution, you build a modular “pipeline” that spans data collection, storage, and recovery. Depending on your constraints, you might combine local storage (a NAS or on‑premise server) for fast access with a remote location (public cloud or managed service) for resilience. You’re free to choose other options—object storage, cross‑datacenter replication, or even cold storage—while ensuring compliance with regulations (GDPR, encryption, etc.) and maintaining full control over your architecture’s future evolution.
Security is paramount: encrypt data at rest and in transit, centralize key management (e.g., HashiCorp Vault), and enforce strong authentication (OAuth2). Edana’s approach includes regular vulnerability scans and key‑rotation policies to minimize attack surfaces. We also assess the environmental impact of backups and favor storage sites powered by renewable energy to support your CSR objectives.
For monitoring, integrate metrics (Prometheus, Grafana) to track backup latency, error rates, and storage usage. Automated alerts notify your teams of deviations, enabling proactive scaling and preventing major incidents.
Achieve a Resilient, Controlled Infrastructure
By combining a 3‑2‑1 backup strategy with a robust DRP, you secure your data and guarantee business continuity. You gain not only strong protection for your information but also a detailed, tested emergency plan aligned with your operational objectives. Leveraging open source, custom development, smart integration of existing tools, and a scalable architecture, you maximize ROI while reducing costs and technical debt over the medium and long term. This flexible approach—centered on security, scalability, and digital transformation—ensures the longevity of your services and the confidence of your stakeholders.
