The Importance of Backing Up Your Data

A Cybersecurity Perspective


A Data Disaster That Could Have Been Prevented

Meet Sam, a small-town café owner whose life revolved around his laptop. One morning he flipped it open to find the infamous Blue Screen of Death. He clicked for the system to attempt an auto repair but it failed. His hard drive had failed. All of his recipes, customer orders, and tax documents had vanished. With no backup to fall back on, panic set in – and so did costly delays and frustration. (Spoiler: this could have been avoided.)

Just like you wouldn’t drive across town without a spare tire or lose sleep without house keys, you shouldn’t rely on a single copy of your data. In fact, backing up your information is crucial for one simple reason: peace of mind. World Backup Day reminds us that in today’s digital world, data underpins almost every part of our lives. If that latte recipe or crucial budget spreadsheet is lost in a crash, the trouble it causes can range from a headache to a full-blown crisis.

Why Data Loss Happens

Data can vanish in many ways, often when you least expect it. Here are some common culprits:

  • Hardware Failure: Hard drives and devices wear out. An old laptop or phone can suddenly die — hard drives typically only last 3–5 years.
  • Ransomware & Malware: Cyberattacks are on the rise. Nearly 60% of organizations were hit by ransomware last year, and some attackers now target backup data too.
  • Accidental Deletion or Software Glitches: It only takes one slip of the finger or a bad software update to lose important files.
  • Theft or Loss of Devices: Laptops, tablets and phones are easy to lose or steal. If your device vanishes and it’s your only copy of the data, it’s gone for good.
  • Natural Disasters: Fires, floods or even a spilled coffee can fry electronics and destroy data.

One survey found that 67.7% of businesses had experienced significant data loss. If it can happen to them, it can happen to you.

Your Backup Safety Net: The 3-2-1 Rule

Backup best practices can be summed up by the famous “3-2-1 rule.” It sounds like a lot, but it’s simple:

  • 3 copies of your data: Your original files + 2 separate backups.
  • 2 different storage types: For example, one on an external drive and one in the cloud.
  • 1 copy offsite: At least one backup should be stored in a separate location, like cloud storage or a physically different location.

Even Ontario Tech’s IT department backs this up: backups help ensure your data is always retrievable — and give you peace of mind.

Types of Backups and Best Practices

No single backup solution fits everyone. Here are common options:

  • Cloud Backup: iCloud, Google Drive, Dropbox, and others copy your files to the internet. Use a strong password and enable MFA.
  • External Drives (HDD/SSD): A fast and cost-effective way to keep backups offline and safe from online threats.
  • Network Attached Storage (NAS): A personal cloud option great for power users or home offices. Still combine it with offsite backups.
  • Other Devices: USB drives or even DVDs can work for smaller backups, but shouldn’t be your only method.
  • Hybrid Strategy: Combine two or more methods for best results — e.g., external drive + cloud backup.

Set backups to run automatically and test them periodically to make sure they work. An untested backup is as risky as no backup at all.

Taking Action: Secure Your Data Today

Try this 30-minute challenge to start securing your data:

  1. Inventory Your Data: What can’t you afford to lose?
  2. Check Current Backups: Are they recent and working?
  3. Choose a Backup Tool: Use built-in tools or sign up for a cloud backup service.
  4. Implement the 3-2-1 Rule: Make extra copies and store one offsite.
  5. Schedule and Encrypt: Automate it and protect with strong credentials.
  6. Test It: Restore a file and verify the backup is usable.

Most backups are “set-and-forget” once configured. Don’t let “I’ll do it later” become “I wish I had.”

Don’t Wait for Disaster

No one plans to lose data, but many treat backups like seat belts — easy to ignore until it’s too late. Fortunately, starting now is simple.

World Backup Day (March 31) is a great reminder to “sync before you sink.” Sign the pledge or set a calendar reminder to check your backups every quarter. That small step could save you a lot of trouble later.

Assess your backup strategy today: make a list, pick a tool, and put your backup plan into motion. Your future self will thank you.
