1 Backup your data regularly

One of the most essential steps to prevent data loss is to backup your data regularly and store it in a safe location. A backup is a copy of your data that you can use to restore your OS in case of a failure or corruption. You can use various tools and methods to backup your data, such as external drives, cloud services, or network-attached storage. You should also follow the 3-2-1 rule, which means having three copies of your data, on two different media, and one offsite. This way, you can avoid losing your data if one of your backup devices fails or gets lost.

Une chose que je trouve utile à ajouter est l'analyse des journaux (logs). En Surveillant régulièrement les journaux système, il est possible de détecter des activités suspectes. Et cela peut aider à identifier les problèmes de sécurité potentiels avant qu'ils ne conduisent à une perte de données.

In my experience, to ensure good integrity and minimal data loss, a RAID configuration is a good place to start. Make sure you keep a sufficient stock of spare material to be able to replace all the disks. Set up staged backups, depending on company policy, local/in the cloud, on tapes, RDX or whatever secured medias. Periodically restore data to ensure your restore process will work the day you need it is another good practice.

A good practice is to separate the disk from the operating system, and keep an exclusive disk for data, but also: Protect your data with frequent backups – locally, in the cloud, or both. Patch the operating system and applications immediately to seal the cracks before attackers exploit them. Strengthen your system with robust antivirus and firewall, protecting against malware threats. Protect sensitive data with encryption, adding an extra layer of protection should breaches occur. Monitor hardware health and power stability, as hardware failures can also lead to data loss. Create a disaster recovery plan outlining the steps to take if data loss occurs unexpectedly. Encourage responsible user practices such as avoiding suspicious links.

2 Update your OS and applications

Another important step to prevent data loss is to update your OS and applications regularly. Updating your OS and applications can fix bugs, improve performance, and enhance security. This can prevent data loss caused by software glitches, compatibility issues, or malware attacks. You can use the built-in features of your OS to check for updates and install them automatically or manually. You can also use third-party tools to manage updates for multiple applications. You should also review your update settings and preferences to ensure that they don't interfere with your work or cause data loss.

3 Use antivirus and firewall software

A third step to prevent data loss is to use antivirus and firewall software to protect your OS from malicious threats. Antivirus software can scan your OS for viruses, worms, trojans, ransomware, and other malware that can damage, encrypt, or delete your data. Firewall software can monitor and control the network traffic to and from your OS, blocking unauthorized or suspicious connections that can compromise your data. You should install reputable antivirus and firewall software on your OS and keep them updated and active. You should also run regular scans and audits to detect and remove any malware.

4 Encrypt your data

A fourth step to prevent data loss is to encrypt your data to safeguard it from unauthorized access or theft. Encryption is a process of transforming your data into an unreadable format that can only be decrypted with a key or a password. Encryption can protect your data from being read, copied, or modified by anyone who doesn't have the key or the password. You can use various tools and methods to encrypt your data, such as built-in features of your OS, third-party software, or hardware devices. You should also choose strong and unique keys or passwords and store them securely.

5 Monitor your hardware and power supply

A fifth step to prevent data loss is to monitor your hardware and power supply to prevent physical damage or failure. Hardware and power supply problems can cause data loss by corrupting, overheating, or shutting down your OS. You should check your hardware components regularly for signs of wear and tear, such as noises, errors, or performance issues. You should also replace or repair any faulty or outdated hardware as soon as possible. You should also use a surge protector or an uninterruptible power supply (UPS) to protect your OS from power fluctuations or outages.

6 Test your data recovery plan

A final step to prevent data loss is to test your data recovery plan to ensure that you can restore your OS in case of a disaster. A data recovery plan is a set of procedures and tools that you can use to recover your data from a backup or a damaged device. You should test your data recovery plan periodically to verify that your backups are valid and accessible, that your recovery tools are working and compatible, and that your recovery time and objectives are realistic and achievable. You should also document and update your data recovery plan as needed.
