Best Cloud Backup Software for Small Business
Worth being direct about a common confusion: Google Drive, Dropbox, and OneDrive are file sync tools, not backup. If ransomware encrypts a synced file, that encrypted version syncs to the cloud too - sync propagates the problem instead of protecting against it. Real backup keeps independent historical versions you can restore to a point before the damage happened.

How we compare
The details that change the decision.
We focus on practical decisions: what the tool costs, what the free or entry plan really includes, where it fits, and which trade-offs are easy to miss. We cross-check vendor documentation and pricing information rather than repeating a feature list.
For a useful comparison, start with the job you need to complete, test the same workflow in each finalist, and check what happens when the free plan stops being enough. Then verify the current price and terms directly with the vendor before you commit.

Do this before paying
Run the same five-minute test on every finalist.
Feature lists are easy to compare and easy to overvalue. If the service offers a free plan or trial, use the same small real-world task in each finalist instead. Record what you can complete, where you hit a limit, and what requires an upgrade.

Detailed comparison
What to know before you choose.
01
Backblaze
Best for Straightforward, affordable unlimited backup with no complexity
Free option
No free tier - flat, low pricing per computer instead.
Trade-off
Genuinely simple, unlimited backup at one of the lowest flat prices in this category - install it and mostly forget about it. It's less full-featured than Acronis for businesses that specifically want backup and antivirus/ransomware protection combined in one product.
02
IDrive
Best for Budget-conscious teams needing to back up multiple devices under one plan
Free option
Small free tier available to try it.
Trade-off
One account can back up multiple computers and servers under a shared storage pool, which is genuinely cost-effective for a small team with several machines. The interface and restore process are less polished than Backblaze's.
03
Acronis Cyber Protect
Best for Businesses that want backup and cybersecurity (anti-ransomware, antivirus) combined
Free option
No free tier.
Trade-off
The integration of backup with active ransomware detection is a real differentiator - it can detect and block an attack in progress, not just help you recover after one. That combined scope comes at a higher price than a backup-only tool like Backblaze.
04
Carbonite (OpenText)
Best for Businesses wanting a long-established, well-known name with automated continuous backup
Free option
No free tier.
Trade-off
Unlimited storage with automatic backup of new and changed files as they're added, and a long track record in this specific category. Now owned by OpenText, and it's priced less competitively than Backblaze for straightforward unlimited backup.
StackPick verdict
The bottom line.
Want simple, affordable, unlimited backup and nothing more complicated? Backblaze. Multiple devices to back up under one account on a budget? IDrive. Want backup and active ransomware protection combined? Acronis Cyber Protect. Whatever you choose, remember: your Google Drive or Dropbox subscription is not backup on its own - pair it with one of these.
