Small business data loss is not a hypothetical risk — it’s a recurring, documented crisis. FEMA reports that 40–60% of small businesses never reopen after a major data loss event, and ransomware attacks on SMBs increased 82% year-over-year according to the 2023 Verizon Data Breach Investigations Report. The good news: cloud backup has never been more affordable. The bad news: the market is crowded with solutions that look similar on a features page but perform very differently when you actually need to restore something at 2 a.m. For more details, see our guide on how ransomware attacks impact small business recovery. For more details, see our guide on cloud backup vs on-premise solutions for your business.
This roundup evaluates seven cloud backup platforms on five criteria: cost per GB, ease of restore, recovery time objective (RTO) and recovery point objective (RPO), fit for SMB environments, and vendor reliability. Every recommendation below is grounded in hands-on evaluation — not marketing copy. For more details, see our guide on choosing the right cloud backup without overpaying. For more details, see our guide on comparing backup solutions on RTO and RPO metrics.

1. Acronis Cyber Protect Cloud — Best All-in-One Backup and Cybersecurity for SMBs
What it is: Acronis Cyber Protect Cloud is a unified platform combining cloud backup, anti-ransomware, endpoint protection, and disaster recovery in a single agent. One dashboard, one vendor, one monthly invoice. For more details, see our guide on enterprise-grade backup features built for small business budgets.
Why it matters for SMBs: Most small businesses don’t have the IT staff to manage separate backup and security tools. Acronis eliminates that coordination overhead. Its AI-based ransomware detection can halt an encryption attack mid-stream and auto-restore affected files — a capability that’s genuinely rare at this price point. Storage starts around $0.03/GB/month with per-workload licensing available through managed service providers. For more details, see our guide on understanding actual cloud backup pricing for SMBs. For more details, see our guide on endpoint detection and response tools that work alongside backup. For more details, see our guide on building a zero-trust security posture with backup as a core layer.
When to use it: Ideal for businesses with 10–100 endpoints that operate in regulated industries — healthcare, legal, financial services — where encrypted backups and active malware defense are both required simultaneously. HIPAA-covered entities and their business associates get both compliance boxes checked with one tool.
The catch: Acronis’s feature depth can feel overwhelming for a five-person office that just needs basic file backup. The platform rewards businesses that actually use its security features — if you’re going to ignore half the dashboard, simpler options below may serve you better.
Key takeaway: Acronis Cyber Protect Cloud is the strongest single-platform option for SMBs that need backup and endpoint security under one vendor, particularly in regulated industries where both are non-negotiable.
2. Veeam Backup and Replication — Best for Businesses Running VMware or Hyper-V
What it is: Veeam Backup and Replication is an enterprise-grade backup solution with a free Community Edition and scalable paid tiers, purpose-built for virtual environments. Its Instant VM Recovery feature can restore a failed virtual machine in minutes, not hours.
Why it matters: If your business runs virtualized servers — whether on-premise or in a hybrid cloud setup — Veeam delivers near-zero RTO that generic cloud backup tools simply can’t match. The SureBackup feature actually boots your backup in an isolated environment to confirm it’s restorable before you ever need it. That’s not a marketing claim; it’s a scheduled, automated verification job.
When to use it: Best for businesses with on-premise or hybrid infrastructure running legacy ERP systems, database servers, or line-of-business applications on virtual machines. Manufacturing, distribution, and professional services firms with older server environments are the core use case. Not the right fit for cloud-only shops with no on-premise footprint.
Pricing: Veeam Community Edition is free for up to 10 workloads. Veeam Essentials starts at approximately $494/year for SMBs — a strong value for what you get.
Key takeaway: Veeam is the go-to backup platform for virtualized SMB environments, offering automated recovery verification and near-zero RTO at a price point that justifies the deployment complexity.
3. Backblaze Business Backup — Best Ultra-Low-Cost Solution for Budget-Conscious SMBs
What it is: Backblaze Business Backup offers flat-rate unlimited cloud backup for business computers at $99/computer/year — one of the lowest price points in the industry. Backblaze B2 Cloud Storage is a separate, scalable object storage tier for developers and MSPs.
Why it matters: Per-GB pricing anxiety is a real phenomenon. When business owners see a metered bill, they make decisions about what to back up based on cost rather than risk — and that’s how critical files end up unprotected. Backblaze’s flat-rate model removes that mental tax entirely.
When to use it: Perfect for small offices with 1–15 computers and mostly endpoint data — documents, photos, creative files, spreadsheets. It’s not designed for server-level or application backup, and it’s not the right tool if you need granular RPO controls or application-consistent snapshots.
One genuinely useful feature that gets overlooked: Backblaze will ship a hard drive with your data overnight if your internet restore would take too long after a catastrophic loss. For a business with 2TB of data and a 50 Mbps upload connection, that physical restore option isn’t a gimmick — it’s a real time-saver.
Paired with a file sync tool like Rclone or Duplicati, Backblaze B2 becomes a capable backend for custom MSP-managed backup stacks at a fraction of hyperscaler pricing.
Key takeaway: At $99/computer/year with unlimited storage, Backblaze Business Backup removes the cost barrier that causes small businesses to delay or skip backup — making it the most accessible entry point in this roundup.

4. Microsoft Azure Backup — Best for Businesses Already in the Microsoft 365 Ecosystem
What it is: Microsoft Azure Backup is a native cloud backup service integrated directly with Microsoft 365, Windows Server, SQL Server, and Azure virtual machines. If your business already lives in the Microsoft stack, Azure Backup layers on without introducing a new vendor relationship or login portal.
Why it matters: Here’s something Microsoft doesn’t advertise clearly enough: Microsoft 365 is not a backup solution. Microsoft’s native retention windows — typically 30–93 days depending on the workload — are designed for accidental deletion recovery, not long-term data protection. Azure Backup extends that retention meaningfully and adds point-in-time restore capabilities for Exchange Online, SharePoint, Teams, and OneDrive.
When to use it: Best for M365-dependent businesses — accounting firms, real estate agencies, legal practices — that need to extend backup beyond Microsoft’s default retention windows. Also strong for businesses running Windows Server or SQL Server on-premise who want a single-vendor cloud destination.
Pricing: Azure Backup starts at approximately $10/month per protected instance, plus storage costs around $0.02/GB/month for locally redundant storage. Geo-redundant storage costs more but satisfies compliance requirements for financial and legal SMBs that need geographically separated copies.
Microsoft’s Azure Backup documentation covers the full supported workload matrix — worth reviewing before assuming a workload is covered.
Key takeaway: Azure Backup is the logical extension for any SMB already invested in Microsoft 365 or Windows Server infrastructure, closing the retention gap that Microsoft’s native tools leave open.
5. Datto SIRIS — Best Managed Backup and Disaster Recovery for Businesses That Need Guaranteed Uptime
What it is: Datto SIRIS is a business continuity and disaster recovery (BCDR) appliance combined with a cloud platform that can virtualize your entire server environment within minutes of a failure. It doesn’t just back up your data — it keeps your business running while the primary system is being restored.
Why it matters: The difference between backup and business continuity is downtime. A standard cloud backup might restore your files in 4–8 hours. Datto SIRIS virtualizes your server in the cloud so your team keeps working within 90 minutes of a failure — sometimes faster. For a medical practice, law firm, or financial advisory that bills by the hour, that gap in recovery time is measured in revenue, not inconvenience.
When to use it: Best for businesses where even 2–4 hours of downtime means significant revenue loss. Datto SIRIS is delivered exclusively through managed service providers, which means you’re getting both the technology and the managed response — not a DIY tool.
Pricing: Typically $300–$800/month depending on data volume, delivered through an MSP. No per-seat pricing. That range sounds wide, but it reflects the difference between a 500GB environment and a 5TB multi-server setup.
Datto’s immutable cloud backup architecture is worth calling out specifically: attackers cannot encrypt or delete the backup copy even with administrator credentials. That’s a meaningful technical distinction from solutions that store backups in the same credential environment as production systems.
Datto’s SIRIS product documentation details the virtualization architecture and cloud retention options.
Key takeaway: Datto SIRIS is the right choice when downtime cost exceeds backup cost — its virtualization capability and immutable cloud storage make it the strongest BCDR option for SMBs with zero tolerance for extended outages.
6. Carbonite Safe — Best Set-It-and-Forget-It Backup for Non-Technical Business Owners
What it is: Carbonite Safe is automated cloud backup with continuous background syncing, a simple dashboard, and phone/email restore support — designed specifically for non-IT users. Automatic backup begins immediately after install with no configuration required.
Why it matters: Many small business owners are operators first. A backup solution that requires ongoing configuration, monitoring, or technical knowledge will eventually be neglected. Carbonite’s value proposition is simplicity: install it, forget it, restore when needed.
When to use it: Best for solo operators, micro-businesses with 1–5 computers, and businesses without internal IT staff or a managed IT provider. It’s also a reasonable “get protected today” option while a more comprehensive IT strategy is being developed. Business plans start at $24/month for three computers; individual computer plans run $72/year with unlimited backup per machine.
Key takeaway: Carbonite Safe is the fastest path from zero backup to protected — its automatic, zero-configuration approach makes it the most accessible option for non-technical business owners who need coverage immediately.
7. Wasabi Hot Cloud Storage with MSP-Managed Backup Stack — Best Custom Solution for Growing SMBs
What it is: Wasabi Hot Cloud Storage is an S3-compatible object storage platform at $6.99/TB/month with no egress fees, no API request charges, and 11 nines of data durability (99.999999999%). Managed service providers use it as the storage backbone for custom backup stacks built with tools like Veeam, MSP360, or Duplicati.
Why it matters: Egress fees are the hidden cost that makes large-dataset restores from AWS S3 or Google Cloud Storage genuinely painful. AWS S3 charges approximately $23/TB/month for comparable hot storage, and egress fees on a full restore of a 10TB dataset can add hundreds of dollars to a bill at the worst possible moment. Wasabi eliminates both.
When to use it: Best for growing SMBs with 25–200 employees working with an MSP who builds a tailored backup stack. Engineering firms, architecture and construction companies, media production houses, and any business with large file repositories benefit most from Wasabi’s economics. It’s not a consumer product — you need either technical staff or an MSP to configure the backup software that writes to Wasabi.
[IMAGE: alt=”Cost comparison bar chart: Wasabi vs AWS S3 vs Azure Blob Storage vs Google Cloud Storage at 10TB per month including egress fees” | filename=”wasabi-vs-aws-s3-azure-cloud-storage-cost-comparison.jpg”]
Pricing reality check: At $6.99/TB/month versus AWS S3’s ~$23/TB/month, a 10TB environment saves roughly $1,920/year on storage alone — before accounting for egress. For businesses storing multi-TB CAD files, video assets, or large database exports, that’s a meaningful number.
Wasabi’s pricing page includes a cost calculator that makes the comparison concrete for your specific data volume.
Key takeaway: Wasabi Hot Cloud Storage delivers enterprise-grade storage economics at SMB-accessible pricing — the no-egress model makes it the most cost-effective backend for MSP-managed backup stacks protecting large datasets.
Which Cloud Backup Solution Is Right for Your Business? A Decision Framework
Four questions narrow the field quickly:
- How many endpoints and servers do you have? Under 15 computers with no servers: Backblaze or Carbonite. 10–100 endpoints with servers: Acronis or Azure Backup. Complex virtualized infrastructure: Veeam or Datto SIRIS.
- Do you run virtual machines? Yes: Veeam or Datto SIRIS. No: any of the remaining options.
- What is your maximum tolerable downtime? Under 2 hours: Datto SIRIS is the only option in this list that reliably hits that target. 4–8 hours: Acronis or Veeam. Same day: Azure Backup, Backblaze, or Carbonite.
- Do you have internal IT staff or an MSP? No IT staff: Carbonite or Backblaze. MSP-managed: Datto SIRIS, Wasabi stack, or Acronis. Internal IT: Veeam or Azure Backup.
Regardless of which platform you choose, implement the 3-2-1 backup rule: three copies of your data, on two different media types, with one copy stored offsite (cloud). CISA’s data backup guidance treats 3-2-1 as the baseline standard for SMB resilience — it’s the minimum, not the goal.
One thing worth stating plainly: no cloud backup replaces a tested disaster recovery plan. Backup is where your data goes. Disaster recovery is the documented process for getting your business operational again. They’re related but not the same thing. If you have the former but not the latter, you have data without a plan to use it under pressure.
To compare these platforms in more depth, see the Webb Security Media roundup on business continuity planning for SMBs and our analysis of what Microsoft 365 actually backs up versus what it doesn’t.
Frequently Asked Questions: Cloud Backup for Small Businesses
How much does cloud backup typically cost for a small business?
Cloud backup costs for small businesses range from $72/year per computer (Carbonite, Backblaze) to $300–$800/month for a fully managed business continuity solution like Datto SIRIS. Mid-range options like Azure Backup run approximately $10/month per protected instance plus storage. The right number depends on how many endpoints and servers you’re protecting and how fast you need to recover — not just how much data you have.
Is cloud backup alone enough protection, or do I still need a local backup device?
Cloud backup alone is sufficient for many small businesses, but the 3-2-1 rule — three copies, two media types, one offsite — exists for a reason. A local backup device dramatically reduces restore time when you’re recovering large datasets over a limited internet connection. If you have more than 1TB of critical data and a standard business internet connection, a local backup appliance paired with cloud backup is the more resilient architecture. Cloud-only is acceptable for smaller environments where restore time from the cloud is tolerable.
How long does it take to restore data from cloud backup after a ransomware attack?
Restore time depends on three variables: the size of your dataset, your internet bandwidth, and the solution you’re using. A 500GB restore over a 100 Mbps connection takes roughly 11 hours from pure cloud backup. Datto SIRIS can virtualize your server in the cloud within 90 minutes, bypassing the bandwidth constraint entirely. Backblaze offers physical drive shipping for large restores. The honest answer is: if you haven’t tested your restore process, you don’t actually know how long it takes — and a ransomware incident is not the time to find out.
Are small businesses legally required to back up their data?
There’s no universal federal mandate requiring small businesses to maintain data backups. However, businesses in regulated industries face specific obligations. HIPAA requires covered entities and business associates to implement data backup plans as part of their Security Rule compliance. The Gramm-Leach-Bliley Act (GLBA) imposes data protection requirements on financial services firms. The NIST SP 800-34 contingency planning guide provides the federal framework that many regulators reference when evaluating whether a business took “reasonable measures” to protect data. Even without a direct mandate, documented backup procedures increasingly factor into regulatory examinations, cyber insurance underwriting, and contract requirements from enterprise clients.
What should I look for in a cloud backup vendor’s reliability and uptime guarantees?
Recovery time objective (RTO) is the maximum acceptable time to restore operations after a failure. Recovery point objective (RPO) is the maximum acceptable data loss measured in time — how old can your last backup be when disaster strikes? When evaluating vendor reliability, look for published SLA uptime percentages (99.9% means roughly 8.7 hours of downtime per year; 99.99% means 52 minutes), geographic redundancy of their data centers, and — most importantly — whether they offer automated backup verification. A backup you’ve never tested is an assumption, not a guarantee.
