Why is cloud backup essential in the face of cyberthreats?

Traditional IT infrastructures are showing their limits. A local backup (on a NAS or external hard drive) remains extremely vulnerable if it is connected to the same network as a compromised workstation.

The ANSSI recommends strictly applying the 3-2-1 rule: keep 3 copies of your data, on 2 different media, with at least 1 stored offsite. This is exactly what cloud backup makes possible. By creating a logical "air gap" (a sealed separation) between your production network and your archives, it ensures that ransomware encrypting your local servers cannot reach your remote backups.

Criteria for choosing a sovereign, expert solution

Not all providers are equal. Entrusting your digital assets requires strong security and compliance guarantees. To comply with the GDPR and protect its know-how, a French company should favor a sovereign infrastructure. That is the commitment made by KiwiBackup.

Here are the trust signals (E-E-A-T) to demand:

  • Certified hosting: Your data must reside in French datacenters holding ISO 27001 and HDS (Health Data Hosting) certifications.
  • End-to-end encryption: Data must be unreadable by third parties, encrypted at the source (256-bit AES) even before it is transferred.
  • Zero Trust architecture: Strong authentication must prevent any compromise of backups, even if administrator credentials are stolen.

FAQ

Cloud storage (such as Google Drive or OneDrive) is a collaboration tool that syncs files in real time. If a file is encrypted by a virus, the infected version is synced. Cloud backup is a vault: it freezes data at a given point in time (versioning) and lets you restore your system to its exact state before the attack.

Yes, provided you choose a professional solution. Solutions like KiwiBackup create an impenetrable barrier between your local infrastructure and the cloud. Even if your internal network is completely compromised, attackers can neither reach nor erase your offsite backups.

Yes, but the choice of provider is crucial. To ensure full GDPR compliance (and avoid extraterritorial laws such as the US Cloud Act), it is imperative to choose a cloud backup whose servers are located in France or in Europe, like KiwiBackup's ISO 27001-certified infrastructure.

Restore time (RTO) depends on your bandwidth and the volume of data. However, modern cloud backup solutions include deduplication and compression technologies that significantly speed up the process, enabling business recovery within a few hours, or even a few minutes for critical files.

Absolutely. Unlike a local backup, which requires being on the company network, cloud backup directly protects employees' computers, wherever they are. As soon as an Internet connection is available, data is backed up seamlessly and securely.
