Everyone agrees backups matter — right up until they have to actually restore one and discover it doesn't work, or it's in the same building that just flooded. The question isn't just whether to back up, but how: in the cloud, on-site, or both? Here's a plain-language comparison to help you protect your data properly.
The two approaches
- On-site backup stores copies of your data on a device in your own location — an external drive, a NAS, or a local backup server. It's fast and fully under your control.
- Cloud backup stores copies in a secure, off-site data centre, accessed over the internet. It's off-premises and resilient to local disasters.
Each has real strengths — and real weaknesses on its own.
On-site backup: fast, but vulnerable
Strengths: Restoring from a local backup is fast — you're not limited by internet speed — and you keep full control of your data.
Weaknesses: It's in the same building as your live systems. A fire, flood, theft, or a ransomware attack that spreads across your network can take out your backup along with everything else. A backup that dies with your server isn't much of a safety net.
Cloud backup: resilient, but dependent on connection
Strengths: Because it's off-site, cloud backup survives local disasters — fire, flood, and ransomware that hits your network. It's typically automatic, encrypted, and easy to scale.
Weaknesses: Restoring large amounts of data depends on your internet connection, so a full recovery can take longer than from a local copy.
Why the best answer is usually both
This is where the well-known 3-2-1 rule comes in: keep 3 copies of your data, on 2 different types of media, with 1 copy off-site. In practice, for most Alberta businesses that means:
- Your live data (copy 1),
- An on-site backup for fast, everyday recovery (copy 2),
- A cloud backup for off-site protection against disaster and ransomware (copy 3, off-site).
Together they cover each other's weaknesses: fast local restores for the common stuff, and a resilient off-site copy for the worst case.
Don't forget your cloud apps
One common blind spot: your data in Microsoft 365 or Google Workspace also needs backing up. "It's in the cloud" is not the same as "it's backed up" — here's why.
The rule that matters most: test it
Whichever approach you use, an untested backup is just a hope. The only way to know a backup works is to actually perform a restore. Backups should be verified and tested regularly — because the worst time to discover a backup is broken is the moment you need it.
The bottom line
On-site backup is fast but vulnerable to local disasters; cloud backup is resilient but slower to fully restore. For most Alberta businesses, the right answer is both — following the 3-2-1 rule — with backups that are verified and tested so you can actually count on them.
