A backup strategy without a recovery plan is only half the job. This guide provides the complete framework for your business to respond to any data loss incident or system disruption: from backup architecture design to the execution of periodic restoration tests.
Phase 1: Inventory and Classification of Critical Assets
The first step is identifying which systems and data are critical to your business operations. Not all data has the same value or the same urgency in case of loss. The typical classification is: critical (systems without which the business cannot operate: ERP, customer database, corporate email), important (systems that create friction if they fail: CRM, shared files, collaboration tools), and short-term dispensable (historical archives, test backups, old project documentation).
Databases
ERP, CRM, and custom application databases. Require transaction-level backup or at minimum hourly backups.
Files and Documents
Contractual documents, invoices, delivery notes, designs, and marketing materials. Daily backup is sufficient for most.
Mailboxes are critical assets often overlooked. Microsoft 365 and Google Workspace have native and third-party backup options.
System Configurations
Server, firewall, switch, and application configurations. Enable much faster reinstallation following an incident.
Phase 2: Defining Recovery Objectives
For each critical asset category, you must define two parameters: RTO (Recovery Time Objective, maximum time to restore) and RPO (Recovery Point Objective, maximum acceptable data loss). These parameters must be aligned with real business needs, not technical perfection. An RTO of 4 hours for the ERP and an RPO of 2 hours is a realistic, achievable objective for most SMEs using modern cloud solutions.
45% of companies that suffer a ransomware attack encrypting their data cannot fully recover it, even after paying the ransom. Immutable backup is the only effective protection.
Phase 3: Recommended Backup Architecture
The most robust backup architecture for SMEs combines local backup (for fast restores), cloud backup (for protection against physical disasters), and immutable backup (which cannot be modified or deleted during a defined retention period, protecting against ransomware). The most commonly used solutions in this segment are Veeam Backup & Replication for virtualised environments, Acronis Cyber Backup for comprehensive protection, and Azure Backup for Microsoft environments.
Phase 4: Designing the Disaster Recovery Plan
Define the Response Team
Designate a coordination lead, a systems technician, and a commercial/executive contact for decision-making.
Document Restoration Procedures
Step by step: which systems to restore in which order, who to contact, and what credentials to use. No ambiguity.
Establish a Communication Tree
Who to notify and when: employees, affected clients, critical suppliers, and — if applicable — the AEPD and sector authorities.
Define Activation Criteria
What type of incident triggers the plan: total data loss, critical system failure for more than X hours, confirmed attack.
Phase 5: Periodic Testing — The Most Important and Most Overlooked Step
An untested backup is not a backup. Regular verification of restores is the most critical and most frequently skipped part of any continuity strategy. The recommendation is to run a full restoration test at least once per quarter, document the results, measure actual recovery times, and compare them against the defined RTOs. If real times exceed targets, the strategy must be adjusted before a real incident occurs.
