What is Data Backup? Why Backups Matter and How to Do Them Right?

4 min read

Imagine waking up one day, grabbing your phone or laptop, and finding all your photos, documents, and precious memories gone. Poof! Just like that. Scary, right? Well, that’s the reality of not having a solid data backup plan in place. But don’t worry, we’ve got you covered! Today, we’re diving into the world of data backup – what it is, why it’s crucial, and how you can easily keep your digital life safe and sound.

ExpressVPN’s survey on people’s backup habits reveals that most people don’t back up their data regularly, with 22% of all respondents not backing up their data at all. The survey also highlights significant differences in data backup habits across countries, with the UK’s concerning 29% of respondents never backing up their data—the highest figure among respondents. This points to an urgent need for better data preservation education in the UK.

What is a data backup?

Okay, so let’s start with the basics. What exactly is a data backup? Think of it as a safety net for all your digital stuff – your photos, videos, documents, everything. It’s like having a spare key to your house in case you lose the original. You make copies of your important files so that if something bad happens – like your computer crashes or you accidentally delete something. Cool, right?

Despite the critical role of backups in preventing data loss from threats like ransomware and hardware failures, many people are still losing important data due to not backing up.

The importance of backing up data

Now, why is backing up your data so darn important? Well, let me tell you a story. Once upon a time, there was a person who didn’t back up their stuff. One day, their computer got infected with nasty malware, and all their files were encrypted – basically held hostage – until they paid a hefty ransom. Yikes! But if they had backed up their data, they could have just shrugged it off and restored everything from their backup. Lesson learned: backups save the day! Data loss has substantial financial and emotional impacts, with some estimates putting the monetary cost at around 12 billion USD annually in the U.S. alone. The most common causes of data loss include system or hardware failures, followed by software corruption, malware, and human error.

How often should you back up your data?

Well, it depends. If you’re like me and mostly use your computer for browsing memes and watching cat videos, you might be okay with backing up once a week. But if you’re a super important business person or deal with top-secret stuff, you might wanna backup every day. According to experts, it’s better to be safe than sorry!

What data are people backing up?

Most folks are all about those memories – you know, photos, videos, the good stuff. But it’s not just selfies and vacation pics. People are also backing up important documents, like school assignments or work stuff. And hey, some even back up their secret recipe for grandma’s famous cookies! Can’t risk losing that, right?

The majority of people tend to prioritize pictures and photos for backup, followed by documents and reports, sensitive data, videos and films, and music and audio files.

Security concerns about data backups

Now, I know what you’re thinking – is it safe to back up your data online? Well, it’s a valid concern. You don’t want some hacker snooping around your private stuff. But here’s the deal: as long as you pick a trustworthy backup service and use strong passwords, you should be good to go. Plus, encrypting your data before backing it up adds an extra layer of security – like wrapping your files in a digital fortress!

You would be surprised to know that 77% of participants (from the survey referenced in the introduction) harbor anxieties regarding the security and privacy of their backup information. These concerns range widely, from significant for 18% of participants to moderate for 29% and to mild for 30%. Only 16% of respondents haven’t considered the risks, and 7% report no concerns about the security of the data they back up.

How to back up your data safely

Alright, it’s time to get down to business. How do you back up your data safely? First things first, pick a reliable backup service that works with your devices. Then, make sure to encrypt your data before sending it off to the cloud – it’s like putting your files in a secret code that only you can unlock. And don’t forget to set up regular backups, so you’re always covered in case of emergency. Easy peasy!

Best Practices for Data Backup

Consistency is Key

Just like watering your plants or walking your dog, backing up your data works best when done regularly. Set yourself a schedule – whether it’s once a week or once a month – and stick to it like glue. Consistent backups mean you’re always one step ahead of data disasters!

Embrace Redundancy

Ever heard the saying “don’t put all your eggs in one basket”? Well, the same goes for your data. Make multiple copies of your important files and store them in different places. That way, if one copy gets lost or corrupted, you’ve got backups on backup to save the day!

Automate, Automate, Automate

Life’s too short to spend time manually backing up your data. That’s where automation swoops in to save the day! Invest in backup software that lets you schedule automatic backups, so you can set it and forget it. Your data will thank you later!

Test, Test, Test

Picture this: you’re in the middle of a data crisis, and you reach for your backups – only to find out they’re as useful as a chocolate teapot. Yikes! Don’t let that happen to you. Regularly test your backups to make sure they’re in tip-top shape and ready to rescue your data in times of need.

Lock it Up Tight

Your data is precious cargo, so treat it like gold! Keep your backups safe and secure by using encryption to scramble your data into a secret code. Store your backups in a secure location – whether it’s a fireproof safe or a trusted cloud provider – and sleep easy knowing your data is under lock and key.


We covered a lot of ground today! From what data backup is to why it’s so important and how to do it safely, you’re now a certified backup expert. So, next time you’re tempted to skip that backup reminder, remember the golden rule: always back up your stuff! Because in the wild world of digital life, a little backup can go a long way. Stay safe out there, folks!
