A laptop dies without warning. Ransomware locks every file on the drive. A backup drive gets stolen along with the laptop sitting next to it. These situations are disruptive, but they do not have to result in permanent data loss. The difference usually comes down to where your backup lives, how often it runs, and whether you can actually restore your files when you need them.

That matters more as ransomware and other forms of data loss continue to affect businesses and individuals. Publicly disclosed ransomware victims climbed nearly 25 percent in the year ending March 2026, according to Black Kite’s latest tracking, marking the fourth consecutive year in which disclosures reached a new high. While a backup cannot prevent every incident, it can give you a reliable way to recover when a device is damaged, lost, stolen, or compromised.

A synced folder is useful for keeping files available across devices, but it is not necessarily a complete backup strategy. A dedicated cloud backup service is designed to keep separate copies of your data and provide recovery options when something goes wrong. The distinction becomes especially important when an incident affects the original files and the devices that contain them.

To make the choice easier, we compared leading cloud backup companies and providers based on factors that matter in real-world use, including pricing, storage limits, security, backup features, and how each service handles file recovery. This guide also looks at when general cloud storage may be enough, when dedicated backup is the safer choice, and which provider makes the most sense for different storage needs and situations.

Our top picks at a glance

Hard drives fail too. Backblaze’s own fleet data puts the annualized failure rate at 1.36 percent for 2025. Add ransomware and simple accidental deletion to the list, and it is clear why dedicated cloud backup beats basic cloud storage for anything you cannot afford to lose.

IDrive ranks as the best overall pick, offering multi-device protection with strong security at a reasonable price. Backblaze wins for unlimited storage without capacity limits, and Acronis leads when security is the priority.

Provider	Best For	Starting Price	Storage	Key Feature
IDrive	Overall value	$99.50/year (5TB)	5TB and up	Multi-device backup
Backblaze	Unlimited storage	$9/month or $99/year	Unlimited	Set-and-forget simplicity
Acronis Cyber Protect Home Office	Security	$49.99/year	Scales by tier	Ransomware protection
Carbonite Safe	Speed	$95.99/year	Unlimited (one device)	Fast, reliable transfers
SpiderOak ONE	Privacy	$6/month	150GB and up	Zero-knowledge encryption
Arq Premium	Budget users	$59.99/year (1TB bundled)	BYO storage or 1TB	Use existing cloud accounts

Best cloud backup service overall

IDrive backs up computers, phones, external drives, and NAS devices under a single account. What sets it apart is snapshot-based disaster recovery, which lets you restore your entire system to a specific point in time rather than grabbing individual files one by one.

The service also includes file syncing, so you get real-time access alongside the scheduled backups running in the background.

Pros

• Multi-device coverage. Unlimited devices, including mobile and NAS, under one subscription
• Hybrid backup. Combines cloud storage with local backup to an external drive
• File syncing included. Real-time sync runs alongside scheduled backups
• Competitive pricing. Lower cost per terabyte than most alternatives, especially at the 5TB tier

Cons

• Slow initial upload. The first backup can take several days with large data sets
• Dense interface. More settings and options than casual users might want
• First-year pricing resets. New signups often get a discount that expires at renewal, so budget for the full $99.50 annual rate going forward

Who this provider fits

IDrive works well if you want one subscription covering your laptop, phone, and external drives without paying separately for each device.

Best cloud backup for small business

Acronis Cyber Protect Home Office does two jobs at once. It backs up your files while actively scanning for ransomware and malware during the upload process. For businesses handling client data or working in regulated industries, this combination matters. IBM’s 2026 Cost of a Data Breach Report puts the global average breach cost at $4.99 million, a record, and up 12 percent from the year before.

Pricing starts around $34.99 a year for the entry Essentials tier, which covers local backup, disk cloning, and ransomware protection. Cloud storage is bundled into the higher Advanced and Premium tiers, which cost more but add off-site backup capacity that scales with the plan you choose.

Pros

• Integrated security. Backup and threat protection in one tool
• Compliance-ready. Supports GDPR and HIPAA requirements
• Centralized control. Manage multiple machines from a single dashboard

Cons

• Premium pricing on higher tiers. Cloud storage capacity comes bundled into the pricier plans, not the entry tier
• Steeper learning curve. The feature-rich interface takes time to navigate

Who this provider fits

Small teams that handle sensitive client information and want backup plus threat protection without juggling separate tools.

Best budget cloud backup solution

Arq flips the typical model. Rather than selling you storage outright, it lets you point your backups at cloud accounts you already pay for, such as Google Drive, Dropbox, or OneDrive, and treat that existing space as a backup destination. You still get proper backup software with versioning and client-side encryption.

Arq also sells its own bundled option, Arq Premium, at $59.99 a year for 1TB of storage shared across five devices. That price is rising to $69.99 on September 1, 2026, the first increase in more than a decade. If you would rather not pay for storage at all, Arq’s software supports Amazon S3, Backblaze B2, Wasabi, and several other destinations alongside the consumer cloud drives most people already have.

Pros

• Lower total cost. Point Arq at storage you already own instead of paying for a separate plan
• Flexible destinations. Works with Google Drive, Dropbox, OneDrive, S3-compatible storage, and more
• Client-side encryption. Files are encrypted before they leave your computer

Cons

• More setup required. Configuration takes longer than plug-and-play options
• Depends on third parties. Your backup relies on another provider’s uptime and storage limits

Who this provider fits

If you are comfortable with a bit of technical setup and already pay for cloud storage elsewhere, Arq lets you turn that existing space into a proper backup system instead of paying for a second subscription.

Best cloud backup for unlimited storage

Backblaze built its entire approach around simplicity. You pay a flat fee, install the software, and let it run. No storage caps, no overage charges, no decisions about what to include or exclude.

Pros

• No capacity limits. Back up as much data as you have on unlimited storage
• Flat-rate pricing. $9 a month, or $99 a year if you pay annually
• Hands-off operation. Continuous backup runs automatically in the background

Cons

• One computer per license. Each machine needs its own subscription
• 30-day version history by default. Older file versions expire unless you pay extra to extend retention
• Computers only. No mobile device backup

Who this provider fits

Video editors, photographers, and anyone with terabytes of data who wants simple, unlimited backup without worrying about hitting storage limits.

Best free cloud backup service

A handful of providers offer free tiers that cover light backup needs. IDrive’s free Basic plan includes 10GB of storage, though the company has signaled it may eventually shift new signups toward a 30-day trial instead, so confirm what is currently on offer before you commit. Other services, including Icedrive, have offered similar entry-level free storage. These free plans typically include versioning and scheduled automation, which puts them ahead of simply dragging files into a folder by hand.

Pros

• Zero cost. Test a provider before spending money
• Basic automation. Scheduled backups run without manual effort

Cons

• Storage caps. Usually limited to 5 to 10GB
• Throttled speeds. Free tiers often run slower than paid plans
• Fewer features. May lack versioning or mobile apps

Who this provider fits

Personal users with minimal data, or anyone who wants to try a service before committing to a paid plan.

Best online cloud backup for speed

Carbonite Safe delivers steady upload and download performance without demanding much attention. The software runs quietly in the background while it keeps your files protected. Personal plans start at $75.99 a year and include unlimited storage, though that coverage applies to a single device.

Pros

• Steady transfer speeds. Reliable performance during backup and restore
• Background operation. Runs without interrupting your work
• Simple interface. Easy to understand and configure

Cons

• Single-device pricing. Each personal plan covers one computer, plus an external drive on higher tiers
• Windows-focused. macOS support is more limited by comparison

Who this provider fits

Users who prioritize reliable, fast backup performance for everyday personal files on a single computer.

Best cloud backup for privacy and security

SpiderOak ONE uses zero-knowledge encryption, meaning the company cannot access your data even if legally compelled to. You hold the only decryption key, and SpiderOak never sees it.

Pros

• End-to-end encryption. Data is encrypted on your device before upload
• Zero-knowledge design. The provider cannot decrypt your files
• Minimal metadata. A no-logs policy limits what the company retains

Cons

• Higher price for the storage you get. $6 a month buys 150GB, less generous than some competitors
• Slower performance. Encryption processing adds overhead
• Less intuitive. The interface prioritizes security over ease of use

Who this provider fits

Journalists, legal professionals, and anyone handling sensitive data who wants maximum confidentiality with no provider access.

Best cloud storage for backup and which services actually qualify

Search results for “best cloud storage for backup” mix two different products together, and that mixing causes real problems. It helps to separate them before you pick anything.

Dedicated cloud backup services

IDrive, Backblaze, and Acronis are built specifically for backup. They run scheduled, automatic jobs in the background, keep multiple historical versions of every file, and can restore an entire system, not just individual documents, after a crash or ransomware attack. Versioning and disaster recovery are the whole point of the product, not a bonus feature bolted on afterward.

General cloud storage with backup capabilities

Services like pCloud and Dropbox are built primarily for file access and sharing, but both now offer backup-adjacent features. pCloud’s Backup tool lets you point a folder or an entire drive at your storage and keep up to a year of file history, and it can pull in files from other cloud accounts as well. Dropbox keeps file versions too, typically 30 days on base plans and considerably longer on higher tiers. Neither one performs full-system imaging or the kind of bare-metal disaster recovery that dedicated backup software handles.

That distinction matters because file sync and cloud storage are not the same job as computer backup. Sync mirrors changes across devices in real time, including deletions and file corruption, which means a ransomware attack or an accidental overwrite can spread to every synced copy before you notice.

Backup is designed to stop exactly that, by keeping independent historical versions you can roll back to. If you are shopping for the best backup cloud storage for a single laptop’s worth of documents, a general storage plan with strong versioning might be enough. If you are protecting a full system, multiple devices, or anything you cannot afford to reconstruct from scratch, a dedicated backup provider is the safer call.

If your files are already spread across several general storage accounts, cloud storage backup solutions like All Cloud Hub let you see everything from one dashboard, so you can spot what is actually protected and what is not before you decide whether dedicated backup is worth adding.

How to choose a cloud backup service

With the options laid out, here is how to figure out which one fits your situation.

1. Storage capacity and pricing

Some providers charge per terabyte, while others offer unlimited storage for a flat rate. IDrive typically delivers the best price per terabyte among the metered plans. Backblaze wins if you have a large amount of data and want a predictable flat cost regardless of how much you store.

2. Backup types and device support

Two backup approaches exist, and understanding the difference helps you pick the right provider.

• File-level backup. Protects the specific files and folders you choose
• Image-level backup. Creates a complete system snapshot for full disaster recovery

Look for providers that cover multiple computers, smartphones, and external drives under one account if you have several devices to protect.

3. Security and encryption standards

Strong cloud backup companies use AES-256 encryption for stored data and TLS 1.3 for data in transit. Zero-knowledge encryption goes further. Only you hold the decryption key, so even the provider cannot read your files.

What is cloud backup and how does it work

Cloud backup automatically copies your files to secure remote servers over the internet. You install software, select what to protect, and the service handles the rest. An initial full backup runs first, then incremental backups capture only what has changed going forward.

This differs from manually dragging files into Google Drive. Dedicated backup providers include versioning, scheduling, and disaster recovery features that basic cloud storage generally lacks.

Cloud backup vs cloud storage vs cloud sync

These three terms get mixed up constantly, but they serve different purposes.

Feature	Cloud Backup	Cloud Storage	Cloud Sync
Purpose	Disaster recovery	File access anywhere	Real-time mirroring
Versioning	Yes, multiple versions	Limited or none	Usually none
Automation	Fully automatic	Manual uploads	Automatic
Examples	IDrive, Backblaze	Google Drive, Dropbox	OneDrive sync

Cloud sync mirrors folders across devices in real time, including deletions and ransomware encryption. That is not true backup. If a file gets corrupted on one device, the corruption spreads everywhere it syncs.

Most users benefit from both, cloud storage for daily access and sharing, plus dedicated backup for protection and recovery.

The 3-2-1 backup rule explained

The 3-2-1 rule offers a simple framework for reliable data protection.

• 3 copies. Your original file plus two backups
• 2 media types. A local drive plus cloud storage
• 1 offsite. At least one copy stored in a different physical location

Cloud backup automatically satisfies the offsite requirement by storing a copy in a remote data center, far from your home or office.

Managing backups across multiple cloud services

Many users already have files scattered across Google Drive, Dropbox, and OneDrive. Managing backups gets complicated when you cannot see everything in one place. You might have important documents in three different accounts with no clear picture of what is actually protected.

Tools like All Cloud Hub let you search and view files across all your cloud accounts from a single dashboard. You can identify gaps in your backup coverage without moving files or switching providers. The connection uses OAuth 2.0, so you sign in directly through each cloud provider. All Cloud Hub never sees your passwords and never stores your files.

 

FAQs about cloud backup services

1. What is the difference between cloud backup and cloud storage services like Google Drive?

Cloud backup automatically protects files with versioning and disaster recovery. Cloud storage provides manual file hosting for access and sharing, but without automatic protection or multiple file versions.

2. How much does 1TB of cloud backup typically cost?

Pricing varies widely. Some providers charge $50 to $100 a year per terabyte, while others, such as Backblaze, offer unlimited storage on a single computer for about $9 a month regardless of how much you store.

3. Is a general cloud storage plan ever enough for backup?

Sometimes. If you only need to protect a modest set of documents and your storage plan keeps a long version history, that can cover you. Once you are trying to protect a full system, multiple devices, or large media libraries, a dedicated backup provider does a more complete job.

4. Can I access my backed-up files from any device?

Most cloud backup services offer web portals and mobile apps, so you can access backed-up files from anywhere with an internet connection.

5. How do I avoid paying for duplicate storage across multiple cloud services?

A multi-cloud manager helps you see all your files in one place. You can spot redundant copies before they inflate your storage costs across providers.
