La data backup<\/strong> is one of the simplest security measures to put in place, and yet one of the most overlooked in SMEs. A ransomware attack, a hardware failure or human error can wipe out years\u2019 worth of customer data, invoices or contracts. Without a reliable, tested backup, it can take days to resume business operations. Here are the fundamental principles for building a robust strategy, even with limited IT resources.<\/p>\n\n\n\n

Understanding what needs to be prioritised for backup<\/h2>\n\n\n\n

Not all of a company\u2019s data is equally critical. Before choosing a solution, it is first necessary to identify what is essential for business continuity in the event of an incident.<\/p>\n\n\n\n

Critical data versus recoverable data<\/h3>\n\n\n\n

The critical data<\/strong> are those whose loss would cause immediate and irreparable damage: customer databases, accounting data, contracts, business application configurations, production databases. Recoverable data \u2014 working documents, old emails, temporary files \u2014 may have a lower backup priority. This distinction allows bandwidth and storage budget to be allocated where the risk is highest.<\/p>\n\n\n\n

Don\u2019t forget the business applications<\/h3>\n\n\n\n

Many SMEs back up their office files but forget about their application databases. However, a customised web application<\/a><\/strong> or business software without its database is unusable. The data backup<\/strong> must cover the files and all the application environments that keep the business running.<\/p>\n\n\n\n

Apply the 3-2-1 rule<\/h2>\n\n\n\n

La rule 3-2-1<\/strong> is the gold standard for data backup: keep three copies of the data, on two different media, one of which is off-site. It\u2019s easy to remember and covers most data loss scenarios.<\/p>\n\n\n\n

Why a single backup isn\u2019t enough<\/h3>\n\n\n\n

A backup stored on the same server as the original data does not protect against a system failure or a cyberattack. A second copy stored on a separate medium provides protection against hardware failures. An off-site copy, in the cloud<\/strong>, protects against physical incidents: fire, flooding, theft.<\/p>\n\n\n\n

Automate to avoid relying on human memory<\/h3>\n\n\n\n

Manual backups are reliable until the day they aren\u2019t. Set up automatic back-ups<\/strong> with a frequency tailored to the criticality of the data \u2014 daily for production databases, weekly for archives \u2014 ensures that no human error creates a breach in the strategy.<\/p>\n\n\n\n

Test the restoration regularly<\/h2>\n\n\n\n

A backup that has never been tested offers no real guarantee. Corrupted files, a poorly documented restoration procedure or a format that is incompatible with the current version of the software can render a backup unusable precisely when you need it most.<\/p>\n\n\n\n

Simulate an incident before it happens<\/h3>\n\n\n\n

A regular restore test \u2014 at least once every three months \u2014 involves restoring the backed-up data to a test environment and checking its integrity. This is the only way to confirm that the backup is actually working.<\/p>\n\n\n\n

Document the return procedure<\/h3>\n\n\n\n

The recovery procedure must be documented and accessible even if the technical manager is absent. In the event of a crisis, every minute counts: clear documentation reduces recovery time and prevents errors under pressure.<\/p>\n\n\n\n

Protecting backups against cyberattacks<\/h2>\n\n\n\n

Modern ransomware also targets backups. A backup accessible from the same network as the infected systems can be encrypted in the same way as the original data. The backup security<\/strong> is therefore just as important as the security of the data itself.<\/p>\n\n\n\n

Isolate backups from the main network<\/h3>\n\n\n\n

Best practice recommends storing at least one backup copy on a storage medium air-gapped<\/strong> (offline) or in a cloud environment with multi-factor authentication and restricted access. This isolation prevents an attack on the main network from simultaneously compromising the backups. A technical and security audit<\/a><\/strong> enables you to assess the actual vulnerability of your backups and rectify any risky configurations.<\/p>\n\n\n\n

Encrypt the backed-up data<\/h3>\n\n\n\n

Data stored off-site must be encrypted to prevent a data breach or unauthorised access to cloud storage from exposing sensitive information. Encryption at source \u2014 before transfer \u2014 is the recommended practice for personal data subject to RGPD<\/strong>.<\/p>\n\n\n\n

Outsource hosting and backups to a reliable partner<\/h2>\n\n\n\n

For an SME without a dedicated IT team, managing its own backup infrastructure poses a significant risk and represents a considerable burden. Outsourcing this responsibility to a technical service provider allows the business to benefit from a professional infrastructure without having to maintain it in-house.<\/p>\n\n\n\n

What professional web hosting covers<\/h3>\n\n\n\n

A application hosting and maintenance<\/a><\/strong> A professional solution includes automatic backups, availability monitoring and disaster recovery plans. Its monthly cost is often less than the cost of a single day\u2019s business interruption.<\/p>\n\n\n\n

Check the service provider\u2019s contractual obligations<\/h3>\n\n\n\n

Before entrusting your data to a cloud or hosting provider, it is essential to check the contractual commitments: frequency of backups, retention period, guaranteed recovery time, and the geographical location of the data to ensure GDPR compliance. The website maintenance<\/a><\/strong> The solution proposed by iterates incorporates these safeguards from the outset. A Brussels grants<\/a><\/strong> may also cover part of these investments in cybersecurity and hosting.<\/p>\n\n\n\n
