Losing your business data — to a dead drive, ransomware, or a simple accidental delete — is one of the few disasters that can genuinely sink a small business. A good online backup service quietly prevents it, for a few dollars a month. But which one? Here are the best online backup picks for a small business in 2026, sorted by what you actually need. (If you want the full method rather than the tools, see our how to back up your business data guide.)

Quick answer: the best backup for most small businesses

• Best cloud (offsite) backup: IDrive — automatic, affordable, backs up all your computers.
• Best local (fast-restore) backup: EaseUS Todo Backup — full disk images to an external drive.
• Best setup overall: use both — that’s the 3-2-1 rule (more below), and it’s what actually protects you.

What to look for in a business backup service

• Automatic + scheduled — the best backup is the one that runs without anyone remembering.
• Offsite/cloud copy — so a fire, theft, or ransomware can’t take out every copy at once.
• Covers all your devices — computers, and ideally servers/NAS.
• Easy restore — getting data back should be simple and fast, not a project.
• Secure — encryption in transit and at rest, ideally with a private key.
• Fair price — backup should cost far less than the data is worth.

Best cloud backup: IDrive

For your all-important offsite copy, a dedicated cloud backup service is the move — and IDrive is a strong, affordable choice for small business. It backs up your computers (and external drives, and in higher tiers servers/NAS) automatically on a schedule, keeps versions of your files, and stores everything encrypted off-site. The standout for a small business is value: a single account can back up multiple devices, so it scales with a small team without costing a fortune. 

Why cloud matters: it’s the copy that survives if your office does not. Fire, flood, theft, or ransomware that encrypts your local machines — your off-site backup is untouched.

Best local backup: EaseUS Todo Backup

Cloud handles the disaster; a local backup handles the everyday “I need this back right now.” EaseUS Todo Backup makes full disk images and scheduled backups to an external drive or NAS — meaning you can restore not just files but an entire machine if it dies, and do it fast without waiting on a download. It’s a great companion to a cloud service, and pairing the two is exactly what the 3-2-1 rule asks for.

Why you want both (the 3-2-1 rule)

The backup standard the pros use is simple: 3 copies of your data, on 2 different types of storage, with 1 copy offsite. In practice that’s your working files + a local backup (EaseUS to a drive) + a cloud backup (IDrive off-site). No single failure — a dead drive, a theft, a ransomware hit — can wipe out all three. Cloud for the disaster, local for the fast restore. That’s the whole strategy.

Also worth knowing: cloud storage is not a backup. Microsoft 365, Google Drive, and Dropbox sync your files — if one is deleted or encrypted, that change syncs everywhere. A real backup keeps separate, recoverable copies. (More on that difference in our cloud storage guide.)

How to choose

• Want the simplest safety net? Start with a cloud backup (IDrive) — automatic and off-site.
• Need fast, full-machine restores? Add a local backup (EaseUS) to an external drive.
• Want it done right? Use both — cloud + local = the 3-2-1 rule, and it’s not expensive.
• Handling sensitive data? Prioritize strong encryption and keep at least one copy offline/off-site so ransomware can’t reach it.

Whichever you pick, the most important step is the one people skip: set it to run automatically, then test a restore every few months. A backup you’ve never tested is just a hope. Our backup how-to walks through the whole setup, and it fits into the wider basics in our cybersecurity checklist.

Frequently asked questions

What is the best online backup for a small business?

For most small businesses, a cloud backup service like IDrive is the best all-round choice — automatic, off-site, affordable, and able to back up multiple devices on one account. For fast full-machine restores, pair it with a local backup like EaseUS Todo Backup.

Is cloud backup better than local backup?

They solve different problems, so the best answer is to use both. Cloud backup is your off-site copy that survives a fire, theft, or ransomware; local backup gives you fast, full restores without a download. Together they satisfy the 3-2-1 backup rule.

Isn’t Microsoft 365 or Google Drive already a backup?

No — those are storage and sync services. If a file is deleted, corrupted, or hit by ransomware, that change syncs everywhere. A real backup keeps separate, recoverable copies you can roll back to. Use a dedicated backup service alongside your cloud storage.

How much does business backup cost?

Very little relative to the risk. A cloud backup service is typically a low yearly fee that covers multiple devices, and a local backup just needs an external drive plus free or low-cost software. For most small businesses it works out to a few dollars a month.
