Best Cloud Backup for Small Business in 2026
Cloud backup can give a small business an off-site recovery copy of important data without requiring the company to maintain all of its backup storage locally. The harder part is choosing a service that protects the systems you actually use. IDrive Business, Backblaze Business Backup, CrashPlan and Carbonite approach small-business backup differently, especially when it comes to computers, servers, NAS devices, Microsoft 365, retention and restore workflows.
Cloud backup vs. online backup for small business: is there a difference?
For small-business buying purposes, cloud backup and online backup are commonly used to describe the same general idea: backup data is transmitted over the internet to storage operated by a service provider.
The terminology matters less than the actual protection model. When comparing online backup solutions for small business use, those protection and recovery details matter more than the terminology. A service marketed as cloud or online backup should still be evaluated for what it protects, how often data is backed up, how long previous versions remain available and how recovery works.
Cloud backup should also not be confused with ordinary cloud file storage or synchronization. Services such as OneDrive can provide valuable synchronization, versioning and recovery features, but synchronization and dedicated backup solve different problems.
What should a small business cloud backup protect?
Before comparing providers, make an inventory of the data that would actually hurt the business if it disappeared.
That may include:
- files stored on employee Windows and Mac computers;
- local databases and application data;
- Windows or Linux servers;
- network-attached storage, or NAS;
- shared departmental folders;
- Microsoft 365 email and cloud files;
- Google Workspace data;
- files created by accounting, design or other line-of-business applications.
A cloud backup product that is excellent for laptops may be the wrong product for a company whose critical data lives on a server or NAS. Workload coverage should therefore come before brand preference.
Cloud backup options at a glance
| Service | Useful to evaluate when... | Important distinction |
|---|---|---|
| IDrive Business | You need to evaluate computers together with server or NAS backup requirements. | Broader workload coverage than a computer-only backup service; verify the current plan and storage allowance for your environment. |
| Backblaze Business Backup | Your primary requirement is straightforward Windows and Mac computer backup. | Business Backup is centered on endpoint/computer protection rather than being an all-purpose server, NAS and SaaS backup platform. |
| CrashPlan | You want to compare endpoint-focused backup or need to evaluate separate server and SaaS options. | CrashPlan offers different products for endpoints, servers and supported SaaS workloads rather than treating them as one identical backup job. |
| Carbonite | You want to compare traditional small-business computer and server backup configurations. | Coverage differs across Carbonite business plans, so verify whether the plan includes the computers and servers you need to protect. |
This is not an overall ranking. These services use different product designs and pricing models, so the useful question is which one fits the systems and recovery requirements of your business.
IDrive Business
IDrive Business is worth evaluating when a company needs more than simple laptop backup. Its business offerings can cover multiple computers and can support additional workloads such as servers and NAS devices, depending on the service and configuration selected.
That broader coverage can be useful for a small office where data is spread across employee computers, a Windows server and network storage rather than living entirely on endpoints.
IDrive also offers separate cloud-to-cloud backup capabilities for SaaS environments such as Microsoft 365. Do not assume, however, that purchasing one backup product automatically means every workload is included. Confirm the exact service, storage allowance and supported systems before purchasing.
Another consideration is capacity-based planning. A business should estimate how much protected data it has today and how quickly that amount is growing rather than choosing a plan only from the introductory price.

Backblaze Business Backup
Backblaze Business Backup takes a more endpoint-centered approach. It is particularly relevant to businesses whose primary requirement is protecting Windows and Mac computers without designing a more complex server-backup environment.
Its current Business Backup offering uses unlimited backup capacity per protected computer and includes centralized administration for business accounts. Backblaze also provides version-history capabilities, with the included period and available extensions subject to the current service terms.
The important limitation is scope. A business should not assume that Backblaze Business Backup is the same thing as a server, NAS or Microsoft 365 backup platform simply because Backblaze also operates cloud-storage infrastructure and other services.
For a deeper look, see our Backblaze Business Backup review.
CrashPlan
CrashPlan is another service worth comparing, particularly for endpoint-focused environments. Its current small-business offerings distinguish among endpoint backup, server backup and supported SaaS backup services.
For endpoint protection, CrashPlan supports Windows, macOS and Linux environments and emphasizes continuous protection, version history and cloud-based recovery capabilities.
That product separation is important when comparing costs. A company that needs endpoint backup only should evaluate the endpoint product, while a company with servers or Microsoft 365 requirements should verify the corresponding service rather than assuming those workloads are automatically included.
Carbonite
Carbonite remains relevant for businesses comparing traditional computer and server backup approaches. Its professional lineup offers different configurations depending on whether the business needs computer backup, server protection or both.
That makes plan selection particularly important. The company should map each protected device and server to the capabilities of the current Carbonite plan rather than assuming every business tier provides identical coverage.
Carbonite also discusses backup as part of recovery from events such as malware and ransomware. As with any provider, the practical question is how your selected plan's versioning, retention and restore capabilities would work during the incident your business is trying to recover from.
Cloud backup comparison: start with workloads, not storage
Storage capacity is easy to compare because it produces a simple number. It is not always the most important number.
Consider a business with 1 TB of files spread across five laptops. Its backup requirements are very different from a business with the same 1 TB stored on a Windows server, NAS appliance and Microsoft 365 tenant.
Before comparing capacity, classify your data by location:
- Endpoints: desktops and laptops;
- Servers: file, application or database servers;
- NAS: shared network storage;
- SaaS: Microsoft 365, Google Workspace and other hosted applications;
- Cloud workloads: systems hosted with infrastructure or application providers.
Then confirm that the backup service actually supports each required category.
How much cloud backup storage does a small business need?
Start with the amount of data that needs protection rather than the total capacity of every disk in the company.
If five computers each have 1 TB drives but only 150 GB of business data on each machine, the protected dataset may be much smaller than 5 TB. Servers, NAS devices and shared data can change that estimate significantly.
Also leave room for growth and version history. Backup storage requirements can increase as files change and older versions are retained.
Capacity planning should therefore include:
- current protected data;
- expected data growth;
- version history and retention;
- new employees or devices;
- servers or NAS systems that may be added later;
- SaaS backup if it is priced or stored separately.
Version history and retention matter as much as backup frequency
A backup service can run frequently and still fail to meet your needs if older recovery points disappear before you discover a problem.
Imagine that an important spreadsheet was corrupted six weeks ago but nobody noticed until today. The useful question is not simply whether the file was backed up yesterday. It is whether the service still has a clean version from before the corruption occurred.
When comparing providers, check how long deleted files and previous versions are retained, whether retention can be extended and whether different workloads follow different policies.
For help determining backup frequency, see How Often Should a Small Business Back Up Its Data?.
What about ransomware?
Cloud backup can be an important recovery layer after ransomware or other destructive events, but having a backup subscription does not guarantee successful recovery.
The business should understand whether previous versions remain available after files are encrypted or overwritten, how administrative access to the backup system is protected, and how a large restore would be performed.
Evaluate questions such as:
- Can you recover files from before the incident?
- How far back can you go?
- Can compromised production credentials affect backup administration?
- Is multifactor authentication available for backup administrators?
- Can you restore many systems efficiently?
- Have you actually tested the recovery process?
Backup complements endpoint security, multifactor authentication, patching and incident response. It does not replace them.
Restore speed is part of the buying decision
A backup is useful only if the business can recover its information within an acceptable period.
Small restores may be easy over an internet connection. Recovering hundreds of gigabytes or several computers can be a different problem, especially when office internet bandwidth is limited.
Before selecting a provider, understand the available restore methods, whether large restores have alternative delivery options, and how much time your business could tolerate without the affected data.
Periodic restore testing is one of the best ways to discover incorrect exclusions, missing permissions or unrealistic recovery expectations before an actual incident.
Should you use both local and cloud backup?
For many businesses, local and cloud backup solve complementary problems.
A local backup can provide fast recovery when a computer or file fails. A cloud copy provides geographic separation if the office experiences theft, fire, hardware loss or another event that affects local equipment.
Using both can also reduce dependence on a single recovery path. Whether that additional complexity is justified depends on how important the data is and how quickly the company needs to recover.
See Local Backup vs. Cloud Backup for Small Business for the full comparison.
Does cloud backup protect Microsoft 365?
Not automatically.
A service that backs up a Windows or Mac computer does not necessarily protect Exchange Online mailboxes, OneDrive accounts or SharePoint sites as separate Microsoft 365 workloads.
This distinction is easy to miss because synchronized OneDrive files may exist on a protected computer. Backing up those local files is not the same thing as providing tenant-level Microsoft 365 backup and recovery.
If Microsoft 365 is important to your business, evaluate that workload separately with our Best Microsoft 365 Backup for Small Business guide.
Cloud backup pricing: watch the billing model
Do not compare backup services using only the promotional price shown on a landing page.
Common pricing approaches include:
- per computer;
- per user;
- by protected storage capacity;
- by server or workload;
- separate SaaS backup subscriptions;
- additional storage or retention charges.
A per-computer unlimited-storage service can be attractive for a few data-heavy endpoints. Capacity-based pricing can make more sense in a different environment. A company with servers, NAS storage and SaaS applications may need to combine multiple services or licenses.
Estimate the cost using your actual environment and expected renewal terms rather than choosing from the advertised starting price alone.
A five-person small-business example
Consider a five-person accounting firm with five Windows laptops, a small Windows file server and Microsoft 365.
If nearly all important files live on the five laptops, an endpoint-focused service may cover much of the requirement. If the file server contains critical shared data, the business must also verify server protection. And if Exchange Online, OneDrive or SharePoint data needs dedicated cloud-to-cloud backup, that becomes a separate workload to evaluate.
Now imagine another five-person company where each employee has a MacBook and all shared information lives in SaaS applications. The number of employees is identical, but the appropriate backup design may be completely different.
This is why "best cloud backup for five users" has no useful answer until the location of the data is known.
Questions to ask before choosing a cloud backup service
- What needs protection? Computers, servers, NAS, Microsoft 365, Google Workspace or something else?
- Which operating systems are supported?
- How often does backup run?
- How long are previous versions and deleted files retained?
- How does a large restore work?
- Can administrators use multifactor authentication?
- Can backup and restore activity be monitored or audited?
- How is the service priced?
- What happens when storage, device or user counts increase?
- Are servers and NAS devices included or separate?
- Is SaaS backup included or a different product?
- Can you test a real restore before depending on the service?
How these cloud backup services differ
The four services in this guide illustrate why a single ranking can be misleading.
IDrive Business is relevant when broader workload coverage and capacity-based planning are important. Backblaze Business Backup is centered more directly on computer backup. CrashPlan separates endpoint, server and SaaS offerings. Carbonite offers multiple business configurations with coverage that depends on the selected plan.
Those differences matter more than declaring one provider universally better.

Frequently asked questions
What is cloud backup for small business?
Cloud backup sends protected business data to remote storage operated by a backup provider so that information can be recovered after deletion, hardware failure, corruption or other data-loss events.
Is online backup the same as cloud backup?
The terms are often used interchangeably in small-business backup products. Instead of focusing on the label, compare workload support, retention, security, restore options and pricing.
Is cloud storage the same as cloud backup?
Not necessarily. Cloud storage and synchronization services are useful for access and collaboration, while dedicated backup products are designed around maintaining recovery copies and restoring data after loss or damage.
Do I still need cloud backup if I use OneDrive?
It depends on your recovery requirements. OneDrive includes valuable versioning and recovery capabilities, but a business may still choose dedicated backup when it needs different retention, administrative separation, broader workload protection or another recovery mechanism.
Does cloud backup protect against ransomware?
Backup can provide recovery points from before a ransomware incident, depending on the service's version history and retention. It should be part of a broader security and recovery plan rather than treated as ransomware prevention.
How much cloud backup storage do I need?
Estimate the amount of business data that actually needs protection, then allow for growth and retained versions. Do not simply add together the advertised capacity of every drive in the company.
Should small businesses keep a local backup too?
A local backup can provide faster recovery for some incidents, while cloud backup provides off-site separation. Businesses with important data may decide that using both gives them a more resilient recovery strategy.
How often should I test cloud backup restores?
Testing should be regular enough that the business is confident its recovery process, permissions and protected data still match expectations. The appropriate schedule depends on how critical the information is and how frequently the environment changes.
Bottom line
The best cloud backup design for a small business starts with the data rather than the provider. Identify whether important information lives on computers, servers, NAS devices or SaaS platforms, then compare services that actually protect those workloads.
IDrive Business, Backblaze Business Backup, CrashPlan and Carbonite each approach the market differently. Compare workload coverage, retention, version history, restore methods, administrative security and long-term pricing before deciding which architecture fits your business.
