Most small business backup advice is either too vague to act on (“use the 3-2-1 rule!”) or too tied to a specific vendor to trust. This guide is neither. What follows is a shortlist of the backup platforms worth considering if you run a small business in 2026, organised by the situation each one actually fits — not by who has the biggest marketing budget.
A note before we start. This is an SMB-tier guide and some of the links in it are affiliate links — if you click through and buy, we may earn a commission. Our editorial standards explain the rules: no affiliate revenue on enterprise-tier comparisons, and on pages like this one, affiliate status never shapes which products we recommend.

What actually matters in 2026
The backup market changed more between 2023 and 2026 than it had for a decade before. Ransomware groups now deliberately target backups before encrypting production systems, because a business without restorable backups is a business that pays. That single behavioural shift has rewritten the buying criteria for small business backup.
Three things now matter more than anything else:
Immutability. Your backup data must be unchangeable for a defined retention period, even by an administrator with full credentials. This is the feature that breaks ransomware’s playbook. If an attacker steals your admin credentials, they can still delete or encrypt mutable backups. They cannot touch immutable ones. Most cyber insurance applications in 2026 ask directly whether you maintain immutable backups — and “no” increasingly means no coverage or a premium hike. We cover the insurance angle in more depth separately.
Server and workstation coverage in one platform. If you have one Windows Server, a NAS, or a couple of Linux machines alongside your laptops, you need a platform that covers all of it. Workstation-only backup with a different server-backup bolt-on is how inconsistent, untested backup strategies happen.
A restore you’ve actually tested. Backup software that hasn’t been tested end-to-end is a storage bill, not a recovery plan. Every platform on this list supports realistic restore testing. The question is whether you’ll actually run the tests.
Everything else — interface polish, storage quotas, specific integrations — is secondary. Get these three right and the rest sorts itself out.
The shortlist at a glance
| Platform | Best for | Starting price | Servers? | Native immutability? |
|---|---|---|---|---|
| iDrive Business | Most small businesses | ~$99.50/yr (unlimited devices, 250GB) | Yes | Via Object Lock |
| Acronis Cyber Protect | Businesses that want backup + security in one | ~$85/yr per workstation (Standard) | Yes | Yes (Advanced tier) |
| Veeam Data Platform Essentials | Server-heavy SMBs with IT staff | ~$500/yr for 5 workloads | Yes | Yes |
| Backblaze Computer Backup | Endpoint-only teams under 10 people | $99/yr per computer | No | B2 Object Lock (separate product) |
| MSP360 + Backblaze B2 | Technically capable teams wanting flexibility | $6/TB/month storage + software | Yes | Yes (Object Lock) |
| Datto SIRIS (via an MSP) | Businesses that buy through a managed service provider | MSP-priced | Yes | Yes |
The detailed notes below explain when each one makes sense and — just as importantly — when it doesn’t.
iDrive Business — the best fit for most small businesses
iDrive Business is the most-business-rounded option on this list, and for a fifteen-to-fifty person company with a mix of workstations, a server or two, and maybe a NAS, it is the default recommendation. Pricing starts around $99.50 per year for 250GB with unlimited devices and servers included, scaling with storage. A 25-person firm with five servers typically lands around $499 per year — roughly ten times cheaper than an equivalent Acronis deployment.
What you’re actually buying is coverage breadth. iDrive handles Windows Server, Linux, NAS devices, SQL, Exchange, Hyper-V and VMware, plus all your endpoints, on a single storage plan. The compliance footprint is unusually comprehensive for the price: SOC 2 Type 2, ISO 27001:2022, HIPAA with BAA, PCI DSS, GDPR. If a client or auditor asks whether your backup provider is certified, iDrive has real answers.
The weaknesses are real but mostly acceptable. The interface is less polished than Backblaze’s. Advanced disaster recovery orchestration — the kind Veeam offers — isn’t here. Once you exceed your storage quota, overages at $0.50/GB/month get expensive quickly, so size your plan with some headroom. And immutability is available via Object Lock on supported storage, but it’s not quite as turnkey as Acronis’s immutable storage tier.
For most small businesses, that combination — broad coverage, genuine compliance, honest pricing — is the right set of trade-offs. Start here unless you have a specific reason not to.
Acronis Cyber Protect — when backup and security need to be one product
Acronis is the right answer when you don’t have the headcount to run backup and endpoint security as two separate tools. The Standard tier runs around $85 per year per workstation and includes backup plus basic anti-malware. The Advanced tier at roughly $109 per year per workstation adds immutable backup storage, advanced anti-ransomware, vulnerability assessment, and patch management in the same agent.
That consolidation genuinely matters. Running backup and endpoint protection as separate agents creates conflicts, management overhead, and coverage gaps. Acronis’s single-agent approach is the strongest argument for the platform, and for small businesses that don’t want to learn two consoles and chase two renewals, it’s a compelling one.
The honest problems: Acronis’s pricing is notoriously complex. Reddit threads on MSP pricing for Acronis read like a warning label — opaque SKUs, surprise physical-server multipliers (reportedly around ten times the virtual-server rate), and per-GB charges that stack on top of per-workload fees if you’re not careful. Ask for the pricing calculator directly from the sales rep before committing. The breadth of features also means a steeper learning curve than iDrive or Backblaze.
Choose Acronis if security consolidation is a specific goal and you have the budget to support it. Don’t choose it if you just want straightforward backup — the feature set you’d be paying for would sit unused.
Veeam Data Platform Essentials — when servers are the centre of gravity
Veeam is the grown-up choice. For a business where virtual machines, Hyper-V or VMware hosts, and business-critical servers are the main concern — not laptops — Veeam’s Data Platform Essentials bundle starts at roughly $500 per year for five workloads. Larger SMBs scale from there.
What Veeam does better than anything else on this list is recovery. Instant VM recovery can have a virtualised server running in minutes directly from backup storage. Disaster recovery orchestration lets you define, document and test RTOs and RPOs with verified plans — the kind of thing a cyber insurer will actually credit in a renewal. Native immutability, air-gapped copies, and anomaly detection during backup are all standard.
The trade-off is operational. Veeam is not a set-and-forget product. It rewards IT staff who understand it and punishes organisations that deploy it without that capacity. If you have one IT generalist and ten staff, Veeam is overkill. If you have a 50-person business with a small IT team and servers you cannot afford to lose, Veeam is probably the right answer — and Microsoft 365 backup is a separate licence (around $2.60/user/month on the Foundation tier) that you’ll want to add.
Backblaze Computer Backup — the simplicity option, with known limits
Backblaze is the best answer for a narrow case: a team of ten or fewer people, all on Mac or Windows laptops, no servers, no NAS, no compliance complexity. At $99 per computer per year with unlimited storage, it is as close to set-and-forget as cloud backup gets. Install, walk away, and the first backup runs quietly in the background for as long as your upload connection holds.
The limits are explicit. Backblaze Computer Backup does not support Windows Server, Linux, databases, or virtual machines. At all. If you have even one server, you need a different product (or Backblaze’s separate B2 Cloud Storage product, paired with third-party software — more on that below). External drives must be reconnected at least every 30 days or Backblaze drops them from the backup set. Restore options are limited to file-level download or a mailed USB drive; there’s no bare-metal or instant-recovery capability.
Per-device pricing also scales poorly. At 25 computers you’re paying $2,475 per year — roughly three times what iDrive charges for equivalent endpoint coverage plus servers. Below ten endpoints with no server needs, Backblaze is genuinely the simplest good option. Above that, the maths tips decisively against it.
MSP360 + Backblaze B2 — the flexible, technical choice
This is the self-assembly option. Backblaze B2 Cloud Storage — a separate product from Backblaze Computer Backup — costs $6 per terabyte per month, with Object Lock for immutability and free egress up to three times your stored volume per month. On its own, B2 is just object storage. Pair it with backup software like MSP360 (formerly CloudBerry), Veeam Community Edition, or Arq, and you have a full backup stack at meaningfully lower storage cost than any of the integrated alternatives.
The appeal is flexibility and cost. At 10TB of backup data, you’re paying around $600 per year for storage versus thousands on workload-based pricing elsewhere. Object Lock gives you genuine immutability. And because B2 is S3-compatible, you can pair it with dozens of backup clients and change your mind later without moving the data.
The cost is complexity. You’re now managing two contracts, two interfaces, and the glue between them. Restores involve more steps. If your backup client and your storage provider disagree about something, you’re the one who resolves it. For a technically competent small business — or one with a capable MSP — this is a serious value option. For everyone else, the integrated platforms are worth the premium.
Datto SIRIS — the MSP-channel option
Datto is worth mentioning because if you buy IT services through a managed service provider, there’s a decent chance they’ll propose Datto SIRIS. It’s a hybrid appliance-plus-cloud backup platform built specifically for the MSP channel, with local instant virtualisation and cloud replication as standard. Recovery is genuinely strong; the platform has earned its reputation.
The editorial caveat is the Kaseya context. Datto was acquired by Kaseya for $6.2bn in 2022, and MSP feedback on that transition has been mixed. Multiple MSP-focused publications and community threads report that post-acquisition support quality has declined, contract terms have tightened, and renewal pricing has crept back up after initial reductions. The product is still capable. The vendor relationship is a known MSP grievance — and one worth raising with your MSP directly if they’re proposing Datto.
You’d buy Datto because your MSP runs it well, not because you went shopping for backup yourself. If you’re reading this as the business owner rather than the MSP, this one isn’t for you to pick — it’s for you to ask hard questions about.
How to actually decide
The decision tree is simpler than it looks.
Start with whether you have servers, NAS, or virtual machines to protect. If yes, eliminate Backblaze Computer Backup immediately. If no, all six options remain viable.
Next, look at your headcount. Under ten people, no servers — Backblaze is the easiest-to-live-with option, or iDrive if you want compliance certifications. Fifteen to fifty people with mixed infrastructure — iDrive is the default. Security consolidation a priority — Acronis. Server-heavy with IT staff — Veeam. Technically capable and cost-sensitive — MSP360 with B2.
Finally, check whether your cyber insurer (or a future one) will require immutable backups. If yes — and the answer in 2026 is increasingly yes — iDrive’s Object Lock, Acronis’s Advanced tier, Veeam’s native immutability, or B2 Object Lock are the paths forward. Backblaze Computer Backup alone will not satisfy that requirement.
One more rule: whatever you pick, test the restore within the first month. A backup you haven’t restored from is a theory, not a plan. Restore a single file. Restore a whole folder. If you have a server, spin up a recovery test on non-production hardware. The platforms above can all do this. Whether you actually do it is up to you.

Frequently asked questions
What does the 3-2-1 backup rule actually mean in 2026?
Three copies of your data, on two different media types, with one copy offsite. The 2026 update — sometimes called 3-2-1-1-0 — adds one immutable or air-gapped copy and zero errors on a tested restore. The point isn’t to memorise the numbers. It’s to make sure that no single failure (a drive, a site, a ransomware attack, a rogue administrator) can destroy every copy of your data.
Do I need immutable backups for cyber insurance?
Increasingly yes. Most cyber insurance applications in 2026 ask directly whether you maintain immutable backups. “No” doesn’t always mean declined coverage, but it typically means a higher premium and tighter exclusions. If your renewal is coming up, plan to have an immutable tier in place before you fill in the renewal questionnaire. iDrive Object Lock, Acronis Advanced, Veeam native immutability, and Backblaze B2 Object Lock all count.
How much should a small business budget for backup?
For a 15–25 person business with a mix of laptops and one or two servers, expect $500–$1,500 per year on a well-chosen platform. Under $500 suggests you’ve under-specified the plan; over $3,000 suggests you’re paying for features you won’t use — or that you’re running Acronis on physical servers, where the pricing tilts sharply.
Is Microsoft 365 backup a separate purchase?
Almost always, yes. Microsoft’s native retention (for Exchange Online, OneDrive, SharePoint, Teams) isn’t backup in the legal-and-recovery sense — it doesn’t protect against malicious deletion, ransomware of cloud-stored data, or long-horizon restore needs. iDrive, Acronis, Veeam, and several MSP-channel products offer dedicated Microsoft 365 backup. Budget separately: roughly $30–$50 per user per year at the Foundation tier.
Can I just use OneDrive, Google Drive or Dropbox as my backup?
No. Sync is not backup. If a file is corrupted, encrypted by ransomware, or maliciously deleted on your local machine, that change propagates to the cloud copy. Versioning gets you some retention but isn’t designed for ransomware recovery and isn’t immutable. Use sync for collaboration and backup software for backup — the two solve different problems.
What happens if my backup provider gets breached?
Depends on the provider’s architecture. Platforms with end-to-end encryption using customer-held keys — iDrive with private encryption key, Backblaze with a private key, Acronis with customer-managed encryption — mean the provider literally cannot read your data, so a breach of the provider is not a breach of your data. Platforms where the provider holds the keys are more exposed. For sensitive data, always enable private encryption keys during setup. On most platforms this can’t be added later.
Do I need a local backup as well as a cloud backup?
It depends on what you’re optimising for. Cloud-only is simpler and survives a site disaster. Local-plus-cloud restores faster for large datasets (no download bottleneck) and is closer to the 3-2-1 rule as traditionally practised. For most small businesses under 2TB of data, cloud-only with verified restore testing is enough. Above that, or where you have strict RTO requirements, add a local NAS or appliance.
