💾 Protecting Your Data

The Complete Guide — 2025 Edition

Why you should back up your PC and emails, which solutions to use, and how to sleep soundly knowing your data is safe.


🛡️ Why Back Up?

Digital data is fragile. A hard drive can fail overnight, a virus can encrypt all your files, and a single wrong click can erase years of work.

The main risks

  • Hardware failure — drives have a limited lifespan
  • Ransomware — malware can lock your files in seconds
  • Human error — accidental deletion, wrong formatting
  • Physical disaster — fire, flooding, theft, lightning
  • Faulty update — a system that won't restart after an update

The reality

If your data only exists in one place, it is not safe.

A backup is not optional — it's insurance. And like all insurance, you only regret not having it when you need it most.


📐 The Golden Rule: 3-2-1

IT professionals rely on a proven rule to guarantee data resilience:

3

Copies of your data

Original + 2 separate backups

2

Different media

Local drive, NAS, cloud, USB stick…

1

Off-site copy

Stored elsewhere, disconnected from the network

📧 Backing Up Your Emails

Your inbox often contains contracts, invoices, professional exchanges and personal memories. Yet few people think to archive them offline.

A hacked account, a provider shutting down or an accidental deletion — and your entire email history is gone forever.

MailStore Home — Free and Essential

A free application that locally archives all your emails from Gmail, Outlook, Yahoo or any IMAP/POP3 server. You keep an offline copy that is independent of your email provider.

  • Completely free
  • Multi-account (Gmail, Outlook…)
  • Ultra-fast search
  • PDF and PST export
  • Works offline
  • English interface

Why archive your emails?


💾 Hardware: Drives and NAS

External USB Hard Drives

An affordable, simple and fast solution. For optimal security, use drive rotation:

  • Drive A — regular automatic backups
  • Drive B — kept up to date, disconnected, stored safely elsewhere
  • Swap them every week

In the event of fire or ransomware, the unplugged drive stays safe.

Our recommendation: LaCie 2 TB →

NAS — Network Storage

A NAS is a small server connected to your home or office network, centralising backups from multiple computers.

  • Synology — intuitive interface, ideal for beginners
  • QNAP — very powerful, aimed at professionals
  • Asustor — excellent value for money

A RAID NAS is not a backup — always replicate your data to an external drive or cloud as well.

Our recommendation: Synology 2-bay →


☁️ Online Backups (Cloud)

Cloud services add a layer of protection by storing your data on remote servers, safe from theft, fire and local disasters.

⚠️ Warning: synchronisation (OneDrive, Dropbox) is NOT a backup. If a file is deleted or encrypted on your PC, the change propagates to the cloud. Use a dedicated backup service with version history instead.


🎯 The Recommended Strategy

Here is a robust, accessible and affordable backup architecture for an individual or freelancer:

  1. Weekly disk image with Macrium Reflect to an external USB drive
  2. Drive rotation: one drive connected for automatic backups, one disconnected and stored safely, swapped every week
  3. Monthly email archive with MailStore Home
  4. NAS (optional but recommended) for intermediate backups and network access
  5. Cloud as a last resort in the event of a major on-site disaster
