In early 2024, a small marketing agency in Cape Town believed they had done everything right when it came to protecting their data.
They had signed up for a well-known cloud backup service, set it to automatically back up all their files, and felt confident they were safe from disasters.
Then one of their employees clicked on a phishing email. It looked like a harmless request to update a password, but it was actually a trap. The hackers got the login details for the company’s cloud account.
Within hours:
Every file in the cloud was deleted.
The “trash” or “recycle bin” folder was emptied.
No copies existed anywhere else.
The company lost years of client work. It took weeks to rebuild what they could, and several clients left because they couldn’t wait.
The big lesson? Cloud backups are useful, but they are not invincible. You need more than just the cloud to be truly safe.
What Exactly Is a Cloud Backup?
A cloud backup is simply a copy of your files stored on someone else’s computer — a secure server that belongs to a backup provider.
You send your data to their servers over the internet, and you can get it back whenever you need it.
Examples of cloud storage and backup services include:
General storage: Google Drive, Dropbox, Microsoft OneDrive.
You can usually set cloud backups to run automatically so you don’t have to remember to do it yourself.
Why Businesses Love Cloud Backups
Access from Anywhere – If you have internet, you can download your files from anywhere in the world.
Automatic Backups – Once it’s set up, backups can happen in the background without manual work.
Easy to Expand – If you need more space, you can upgrade without buying more physical equipment.
Safe from Local Disasters – If your office burns down or floods, your files are still safe in the cloud.
Where Cloud Backups Can Fall Short
While cloud backups solve many problems, they also have risks people often overlook:
They Can Be Hacked – If hackers steal your login details, they can delete your cloud files just like they’re on your own computer.
Ransomware Can Spread to the Cloud – If your cloud account is always connected to your computer, certain types of ransomware can encrypt your cloud files too.
Accidental Deletion – If someone in your company deletes a file in the cloud and you don’t notice in time, it might be permanently gone after the service’s retention period.
Limited Retention – Many cloud services only keep deleted files for 30–90 days before wiping them forever.
You Depend on the Internet – If your internet goes down, you can’t access or restore your files until it’s back.

Best Practices for Using Cloud Backups Safely
If you want to use the cloud for backups, you should follow some important safety steps:
Enable Multi-Factor Authentication (MFA) – Use a password plus a code sent to your phone or generated by an app. This makes it much harder for hackers to log in, even if they know your password.
Use Different Credentials – Don’t use the same login for your cloud backup as you do for your email or main systems.
Pair with Local Backups – Keep an extra copy of your files on a local device like an external hard drive or office server for quick recovery.
Add Immutable or Air-Gapped Copies – Have at least one copy that can’t be changed or deleted (immutable) or is kept completely offline (air-gapped).
Test Your Backups Regularly – Try restoring a few files every month to make sure your backups actually work.
The Cloud’s Role in the 3-2-1-1-0 Strategy
The 3-2-1-1-0 rule says you should have:
3 copies of your data.
2 different storage types.
1 copy off-site.
1 immutable or air-gapped copy.
0 errors after verification.
Cloud backups work perfectly for the “1 off-site copy” part of the rule — but you still need the other layers of protection to be truly secure.

Real Example
A retail chain in Dubai used Vembu’s hybrid backup method.
Every store kept a local copy for quick restores.
The head office kept immutable backups in the cloud.
When ransomware infected their office systems, the cloud backups remained untouched, and they restored everything in just a few hours — without paying a single dirham in ransom.
The Big Takeaway
Cloud backups are a powerful part of a data protection plan, but they are only one piece of the puzzle.
The safest approach is to combine cloud backups with local, immutable, or air-gapped copies — so no single attack or disaster can wipe out all your data.
If your only backup is in the cloud, you’re taking a big risk. Let’s create a hybrid backup plan with Vembu BDR Suite so your business can survive anything. [Book your free consultation today]
FAQ
1. What exactly is a cloud backup?
A cloud backup is simply a copy of your data stored on the internet instead of only on your own computer or office server.
Your files are sent over the internet to a secure data center owned by a backup provider.
That provider’s servers keep your files safe and ready for you to restore whenever you need them.
Think of it like renting a safe deposit box at a bank — you keep a copy of your important documents there so that even if your house is damaged, those documents are safe.
2. How is a cloud backup different from cloud storage?
Many people confuse the two:
Cloud storage (like Google Drive or Dropbox) is mainly for storing and sharing files you work with regularly.
Cloud backup is designed for complete protection — it automatically copies your files (and sometimes whole systems) to the cloud so you can recover them if something goes wrong.
Cloud backups often include features like version history, scheduled backups, and full system recovery — not just file storage.
3. Why do businesses like cloud backups?
Access from anywhere – As long as you have internet, you can get your files from anywhere in the world.
Automation – You can set it up once, and it will back up files regularly without you having to remember.
Scalability – If you need more storage space, you can just upgrade your plan — no need to buy new hardware.
Protection from local disasters – If your office burns down or is flooded, your cloud copy is safe in another location.
4. Are cloud backups completely safe?
No backup is 100% safe. Cloud backups are very secure, but they can still be hacked if someone steals your login details, or files can be deleted by mistake.
Also, if your internet goes down, you won’t be able to access your files until it’s restored.
5. How can hackers attack my cloud backups?
Hackers often use phishing emails to trick you into giving them your username and password.
Once they have those details, they can log into your cloud account and:
Delete files.
Encrypt them with ransomware.
Change settings to block recovery.
Some advanced ransomware can even target files in your connected cloud storage.
6. What are the risks of relying only on the cloud?
If you only use cloud backups, you are at risk of:
Hacking and ransomware attacks that can reach your cloud data.
Accidental deletions by employees.
Limited file recovery periods — some services permanently erase deleted files after 30–90 days.
Internet outages that prevent you from accessing your backups.
7. How can I make my cloud backups more secure?
Turn on Multi-Factor Authentication (MFA) – This adds an extra login step, like a text message code, to keep hackers out.
Use different passwords – Don’t reuse passwords from other accounts.
Combine with local backups – Keep an extra copy of your data in your office for faster restores.
Add immutable or air-gapped backups – So even if hackers get in, they can’t delete or change those copies.
Test your backups – Try restoring some files regularly to make sure everything works.
8. What does “immutable” mean in cloud backups?
Immutable backups are locked for a set period of time — no one (not even you) can delete or edit them until that time is over.
This makes them safe from ransomware, accidental deletions, and insider threats.
9. Can cloud backups get infected with ransomware?
Yes — if your cloud account is linked directly to your computer or server, ransomware could encrypt the files in the cloud too.
That’s why adding immutability or an offline copy is important.
10. Are cloud backups enough on their own?
No. Cloud backups are best when they are part of a bigger plan that also includes:
Local backups for quick recovery.
Immutable or air-gapped copies for disaster situations. This way, if one copy is lost, you still have others.
11. How does the 3-2-1-1-0 backup rule use the cloud?
In the 3-2-1-1-0 rule:
3 copies of your data.
2 different types of storage.
1 copy off-site (the cloud is perfect for this).
1 immutable or air-gapped copy.
0 errors after testing your backups.
The cloud fits the “off-site” part — but the other layers are just as important.
12. What’s the difference between cloud backup and hybrid backup?
Cloud backup stores your data only in the cloud.
Hybrid backup stores it both locally (for speed) and in the cloud (for safety). Hybrid backup gives you the best of both worlds — fast restores and disaster protection.
13. How does Vembu BDR Suite make cloud backups safer?
Encrypts files before sending them to the cloud.
Offers immutable backups so hackers can’t delete them.
Supports hybrid backup for both speed and safety.
Lets you set custom retention rules for deleted files.
Automatically checks backups for errors so you can trust them.
14. Does internet speed matter for cloud backups?
Yes. Faster internet means backups and restores will happen more quickly.
But even with slower internet, cloud backups are still valuable for long-term protection.
15. How do I get started with cloud backups?
Choose a reliable provider like Vembu.
Decide how often you need to back up (daily, hourly, or continuous).
Pair cloud backups with local and immutable/air-gapped copies for complete protection.
Test regularly so you’re sure you can recover your files when you need to.
