How to backup your data and protect it from ransomware

Secure your digital assets against ransomware with expert data backup strategies and robust protection tips.

In an age where data is as valuable as currency, protecting it from threats like ransomware is not just a luxury, but a necessity. Ransomware is a type of malware that encrypts a victim’s files, with the attacker then demanding a ransom from the victim to restore access to the data upon payment. This article will guide you through the critical steps of backing up your data and shielding it from ransomware attacks.

Understanding the Importance of Data Backup

Data backup is the process of copying or archiving files and folders for the purpose of being able to restore them in case of data loss. Data loss can be due to many reasons including hardware failure, natural disasters, or as often seen in recent times, ransomware attacks. Having a reliable backup solution ensures that you can quickly recover your data without succumbing to the demands of cybercriminals.

Choosing the Right Data Backup Solution

When it comes to backing up your data, there are multiple options available. The 3-2-1 backup rule is widely regarded as a best practice in this domain. This rule suggests having at least three total copies of your data, two of which are local but on different devices, and at least one copy offsite.

  • Local Backups: Local backups involve storing your data on physical devices like external hard drives or NAS (Network-Attached Storage). They are convenient for quick recovery but can be susceptible to physical damage or theft.
  • Cloud Backups: Cloud backup services provide remote storage that is maintained by a third party. This method protects your data from local threats and allows for easy access from any location with internet connectivity.

Implementing a Robust Backup Strategy

A well-structured backup strategy takes into account not just where the data is stored, but also how frequently the backups are performed.

  • Regular Backups: Schedule regular backups. Daily backups are ideal for ensuring that you lose no more than 24 hours of data.
  • Versioning: Utilize backup solutions that support versioning, which keeps multiple versions of your files as they are updated. This is crucial if you need to recover files that were encrypted by ransomware to a point before they were compromised.

Securing Your Backups

Securing your backups is as important as creating them. Follow these practices to ensure the security of your backups:

  • Encryption: Encrypt your backup data. Whether on a physical device or in the cloud, encryption will prevent unauthorized access.
  • Physical Security: If you’re using physical devices for backup, ensure they are stored in a secure location to prevent theft or damage.
  • Access Control: Limit the access to your backups. Only trusted individuals should have the ability to restore data from backups.

Ransomware Protection Techniques

While backups are your safety net, protecting your systems from ransomware in the first place is equally vital.

  • Antivirus Software: Ensure that you have reliable and updated antivirus software installed on all systems. This software can often detect and quarantine ransomware before it causes damage.
  • Software Updates: Keep your operating system and all applications updated. Many ransomware attacks exploit vulnerabilities in software that have already been patched by the manufacturer.
  • Email Vigilance: Be cautious with emails, especially those with attachments or links, as phishing is a common vector for ransomware attacks.

Restoring Your Data in the Event of a Ransomware Attack

If you find yourself the victim of a ransomware attack, the following steps should be taken to restore your data:

  • Isolate the Infected System: Prevent the ransomware from spreading by disconnecting the infected system from your network.
  • Analyze the Impact: Determine which files have been encrypted and identify the type of ransomware, if possible.
  • Wipe and Reinstall: In some cases, the best course of action may be to completely wipe the infected system and reinstall everything from scratch.
  • Restore from Backups: Once the system is clean, restore your data from the backups. If your backups are also infected, you may need to go back to an earlier version.


The safety of your data in the digital realm should be managed with the utmost care and attention. By employing a comprehensive backup and protection strategy, you can shield your assets from the dire consequences of ransomware attacks. Remember, the key is not just to back up your data but to also protect these backups with the same vigor as you would the original data.
