Best Cloud Backup Services in 2026: 10 Plans Compared

Your photos, home videos, scanned documents and creative projects can disappear with a failed drive, a stolen laptop or one mistaken deletion. The best cloud backup services reduce that risk by copying selected files, folders or an entire computer to an off-site account and keeping recoverable versions when files change.

For most people, Backblaze is the best cloud backup service overall because it combines unlimited storage with automatic backup and simple pricing for one Windows PC or Mac. IDrive is the stronger choice for several computers and mobile devices, while Acronis True Image is better for people who want full-system images in both local and cloud storage.

This guide compares current personal cloud backup plans, storage and device limits, version retention, restore choices and important restrictions. It focuses on protecting personal files and media, not enterprise backup platforms. Prices were checked against provider information in August 2026, but promotions, taxes and regional pricing can change.

Cloud Backup Reviews

1. Backblaze: Best Cloud Backup Service Overall

Best for: People who want automatic, unlimited backup for one Windows PC or Mac.

Backblaze earns first place because it removes the two decisions that stop many home users from backing up properly: which folders to select and how much storage to buy. After installation, the app automatically backs up user-created files on one computer and connected external drives. Storage is unlimited, and there is no separate charge based on the number of photos or videos uploaded.

The service costs $9 per month, $99 per year or $189 for two years per computer. It starts with 30 days of version history, but account holders can enable one-year version history at no additional cost. Forever version history is optional and costs $0.006 per GB per month for versions and deleted files older than one year.

• Unlimited backup for one Windows or Mac computer
• Automatic and continuous file backup
• Connected external-drive backup
• Web downloads, mobile access and mailed-drive restore options
• 15-day free trial with no credit card required

Pros: Unlimited storage, minimal setup, transparent per-computer pricing and a useful mailed restore drive for very large recoveries. One-year version history is now free when enabled.

Cons: Every computer needs its own subscription. Personal Backup does not back up a NAS, and an external drive must be reconnected regularly so Backblaze knows it still belongs in the backup. It is a file backup service rather than a bootable full-system imaging tool.

Who should avoid it: Households that want one subscription for several computers, Linux users and anyone who needs direct NAS backup.

2. IDrive: Best for Multiple Computers and Devices

Best for: Families and individuals whose photos and files are spread across several computers, phones and external drives.

IDrive uses a shared storage allowance instead of charging for every computer. The Personal plan supports multiple computers for one user, plus iOS and Android devices. That makes it a better value than Backblaze when a desktop, laptop and external drive all need protection, provided the total data fits within the selected capacity.

The 5TB Personal plan costs $11.99 month to month. Annual billing is advertised at an introductory equivalent of $6.99 per month for the first year, with standard renewal pricing equivalent to $9.99 per month. IDrive clearly states that its annual discount applies to the first year, so compare the renewal total rather than choosing on the promotional number alone. A free 10GB plan is available for a small trial.

• 5TB, 10TB and larger Personal plans
• Backup for multiple Windows, Mac and Linux computers
• Mobile photo and video backup
• External-drive backup and disk-image options
• IDrive Express physical transfer for large backups or restores
• Up to 30 previous file versions

Pros: One allowance covers multiple computers, platform support is broad, and the combination of file backup, disk imaging, sync and physical transfer tools is unusually complete.

Cons: Storage is capped, the interface exposes more choices than Backblaze, and first-year annual pricing is lower than the standard renewal price. Monitor usage so old device backups do not consume the allowance unexpectedly.

Who should avoid it: Anyone with more than 5TB of data on one computer who values unlimited capacity and one-click simplicity more than multi-device coverage.

3. Acronis True Image: Best for Local and Cloud System Images

Best for: Users who want full-disk imaging, local backup, cloud backup and recovery tools in one application.

Acronis has renamed Acronis Cyber Protect Home Office back to Acronis True Image. It is the most complete system-backup product in this ranking because it can create full images, clone disks and back up individual files and folders. This is useful when the goal is not only to recover family photos, but also to rebuild a computer after a failed drive.

The plan distinction matters. Essentials starts at $49.99 per year but includes local storage only, so it is not the plan to compare with a cloud backup service. Advanced starts at $72.99 per year and includes 50GB of cloud storage, expandable to 500GB. Premium starts at $124.99 per year with 1TB included and higher storage options. Pricing varies with the number of protected computers.

• Full-image, file, folder, disk and partition backup
• Local and cloud destinations on Advanced and Premium
• Active disk cloning and recovery-media tools
• Windows, macOS and mobile-device support
• Integrated anti-ransomware and malware features

Pros: Excellent recovery flexibility, full-system images and a genuine local-plus-cloud workflow. It is a strong fit for a 3-2-1 plan when paired with an external drive.

Cons: Cloud storage is not included in Essentials, and Advanced starts with only 50GB. The product has more features, settings and plan choices than many home users need.

Who should avoid it: Anyone seeking the simplest unlimited photo and video backup. Backblaze is easier, while IDrive usually offers more cloud capacity for the money.

4. Arq Backup: Best for a Flexible 3-2-1 Backup Setup

Best for: Mac and Windows users who want encrypted backups across cloud storage, a NAS and local drives.

Arq takes a different approach from most online backup services. Arq 7 is a backup application that sends encrypted data to storage you control, including Backblaze B2, Amazon S3, Google Drive, Wasabi, SFTP servers and compatible NAS or local destinations. Arq Premium bundles the app, web access and 1TB of managed cloud storage for up to five computers.

Arq Premium costs $59.99 per year at the time of this update. Arq says that price will increase to $69.99 on September 1, 2026. Extra Premium storage costs $0.00599 per GB per month. The standalone Arq 7 license costs $49.99 per computer and will rise to $59.99 on the same date, but storage-provider charges are separate.

• Client-side encryption before data leaves the computer
• Multiple simultaneous backup destinations
• Point-in-time file and folder recovery
• Custom schedules, retention rules and bandwidth limits
• Documented backup format that reduces provider lock-in

Pros: Exceptional destination choice, strong privacy design and useful control over version retention. Premium offers good value for five computers, while Arq 7 lets experienced users shop separately for storage.

Cons: It needs more configuration than Backblaze. With Arq 7, the total price depends on storage and download charges from a separate provider. It does not create the same kind of full bootable system image as Acronis.

Who should avoid it: People who want one automatic default with no destination or retention decisions.

5. Carbonite Safe: Best for Simple Backup With Phone Support

Best for: Windows or Mac users who want unlimited storage for one computer and access to phone support.

Carbonite Safe is a straightforward alternative to Backblaze, with automatic file backup and unlimited cloud storage on every Personal plan. Its main advantage is the familiar set-it-and-forget-it design combined with phone, chat and email support. Its main disadvantage is plan gating: features that photographers and home-video owners may expect are not all included in Basic.

Standard prices are $95.99 per year for Basic, $131.99 for Plus and $161.99 for Prime. Basic covers one computer but does not include external-drive backup or automatic video backup. Plus adds one external drive and automatic video backup. Prime adds a courier recovery service. Promotions may reduce the initial price, but compare the undiscounted renewal cost before subscribing.

• Unlimited cloud storage for one Windows PC or Mac
• Automatic file and folder backup
• External-drive and automatic video backup on Plus and Prime
• Courier recovery on Prime
• Phone, chat and email assistance

Pros: Unlimited capacity, simple setup and accessible support. The feature ladder is easy to understand once you know which plan includes video and external drives.

Cons: One subscription protects one computer, and the lowest plan excludes two features that matter for large personal media collections. Plus and Prime cost more than Backblaze.

Who should avoid it: Users with several computers, anyone who needs NAS backup and people who want external-drive or video coverage at the entry price.

6. Jottacloud: Best Unlimited Plan for Personal Photos and Videos

Best for: Individuals who want unlimited personal storage across all their devices, or families that prefer a shared storage allowance.

Norway-based Jottacloud combines computer backup, mobile photo backup, file sync and photo browsing. The Personal plan is especially attractive for large non-commercial media collections because one user can back up all devices with unlimited storage. Families can instead choose a Home plan with five user accounts and a fixed shared allowance.

The unlimited Personal plan costs $12.99 per month. Jottacloud gradually reduces upload speed after 5TB, so unlimited does not mean unchanged performance at every usage level. Home costs $7.99 per month for 1TB or $15.99 per month for 5TB and includes five users without the same bandwidth limitation. A free 5GB plan is available.

• Unlimited Personal plan for one user and all devices
• Home plans for five users
• Computer backup and automatic mobile photo backup
• Photo browsing, sharing and file sync
• Data stored in Norway under European privacy law

Pros: Strong fit for personal photos and videos, generous multi-device rules and sensible household plans. It brings backup and photo access together without charging per computer.

Cons: Upload speed is progressively reduced after 5TB on the unlimited plan, and Personal is limited to personal, non-commercial files. Version history is less extensive than the long-retention choices from Arq or SpiderOakONE.

Who should avoid it: Professionals backing up paid client work on the Personal plan, privacy buyers who require zero-knowledge encryption and users who need extensive historical versions.

7. SpiderOakONE: Best for Zero-Knowledge Privacy

Best for: Privacy-focused users who need backup, sync and historical versions on Windows, macOS and Linux.

SpiderOakONE encrypts backup data on the device and says it cannot read file contents, filenames, metadata or passwords. All current plans include unlimited devices, backup, sync, sharing and historical versions. Point-in-time recovery lets users return selected files or folders to an earlier state after accidental changes, corruption or ransomware.

Plans cost $6 per month or $69 per year for 150GB, $11 per month or $115 per year for 400GB, $14 per month or $149 per year for 2TB, and $29 per month or $320 per year for 5TB. The 2TB plan is the most relevant comparison for a sizable photo library, but it is more expensive than capacity-first alternatives.

• Client-side end-to-end encryption
• Backup, sync and sharing on unlimited devices
• Windows, macOS and Linux support
• Historical versions and point-in-time recovery
• Folder selection instead of an automatic whole-computer default

Pros: Excellent privacy model, unlimited device count and strong version-based recovery. It supports Linux as well as Windows and macOS.

Cons: Storage is capped and relatively expensive. Zero-knowledge design makes password and recovery-key management critical because the provider cannot simply recover access to encrypted data for you.

Who should avoid it: Anyone likely to lose a password or recovery information, and households that mainly want the largest storage allowance at the lowest price.

8. ElephantDrive: Best for NAS and Multi-Device Households

Best for: Households that need computer, mobile and compatible NAS backup under one account.

ElephantDrive is one of the few consumer-facing choices in this comparison that specifically promotes NAS backup as well as desktop and mobile apps. Its Home offering includes 1TB, support for up to 10 devices and three subaccounts. Backup, sync and file sharing are combined in the same service, which can simplify a household setup.

The Solo plan costs $10 per month or $100 per year for 1TB. The Family plan costs $20 per month or $200 per year for 2TB and supports more subaccounts. Extra storage is available at an additional cost. Users should confirm compatibility with their exact NAS model before purchasing because integrations and app availability vary by device maker.

• Apps for Windows, macOS, Linux, iOS and Android
• Support for compatible NAS devices
• Automatic backup plus sync and sharing
• Multi-device and subaccount allowances
• Monthly and discounted annual billing

Pros: Broader device coverage than per-computer services and a useful NAS option for households that keep their photo library on network storage.

Cons: Storage is capped, the service costs more than IDrive for a similar capacity, and lower plans can impose maximum individual file-size limits. NAS support needs model-by-model verification.

Who should avoid it: People with one computer and a very large library, or anyone who does not need NAS and multi-user features.

9. pCloud: Best Lifetime Cloud Storage and Backup Hybrid

Best for: Users who want cloud storage, device access and selected-folder backup with a one-time payment option.

pCloud is primarily a cloud storage and sync service, not a full computer backup platform. Its desktop app can continuously protect selected folders, and its mobile app can upload photos and videos. This makes it convenient for people who want their media available across devices, but the behavior is closer to a synchronized cloud drive than an isolated archive.

Current lifetime offers list 500GB for $199, 2TB for $399 and 10TB for $1,190 as one-time payments. Those promotional prices can change. Paid plans include file recovery for up to 30 days, while Extended File History can extend recovery to 365 days for an additional charge. pCloud Encryption, its client-side zero-knowledge option, is also a separate add-on rather than a standard feature of every personal plan.

• Lifetime and subscription payment choices
• Selected-folder backup and automatic mobile uploads
• Sync, sharing and built-in media playback
• 30-day recovery on paid plans
• Optional 365-day history and client-side encryption add-ons

Pros: Strong media access, useful sharing tools and the possibility of avoiding a recurring storage subscription. It works well as a cloud copy of actively used folders.

Cons: It is not a full-system backup, standard recovery history is short, and important privacy or extended-history features cost extra. A lifetime plan is tied to the service and terms continuing, so it should not be your only copy.

Who should avoid it: Anyone who wants automatic whole-computer protection, long version retention by default or a true archival backup independent of synchronized deletions.

10. Internxt: Best Privacy-First Storage and Scheduled Backup Hybrid

Best for: Privacy-conscious users who want encrypted cloud storage with scheduled folder backups on several computers.

Internxt Drive is an open-source, zero-knowledge cloud storage service with a backup feature in its Windows, macOS and Linux desktop applications. Paid users can select folders and run backups manually or on a schedule such as every six hours, every 12 hours or daily. It is a useful privacy-first storage hybrid, but it ranks last because its recovery and versioning system is less mature than the dedicated backup products above.

Internxt offers 1TB, 3TB and 5TB annual and lifetime plans. Advertised introductory prices and lifetime offers change frequently, so check the full renewal or one-time total at checkout. On annual subscriptions, a first-month discount does not necessarily reduce every month of the one-year commitment.

• Zero-knowledge end-to-end encryption
• Open-source desktop and mobile applications
• Scheduled folder backup on Windows, macOS and Linux
• Storage, sync and sharing in the same account
• Limited document versioning on higher plans

Pros: Strong privacy positioning, multi-platform desktop support and a transparent open-source approach. It can provide an encrypted off-site copy of selected folders.

Cons: Backups require folder selection, version history is restricted by plan, file type, file size and time window, and the service is still primarily cloud storage. It is not a disk-imaging tool and should not replace a more complete local backup.

Who should avoid it: Anyone who needs automatic whole-computer coverage, deep version history or the simplest possible recovery workflow.

How We Ranked the Best Cloud Backup Services

Pixoneye ranked these services for personal photo, video and file protection. We did not run a controlled upload-speed or full-restore benchmark for this update. The comparison is based on current provider plan pages and documentation, with the most weight given to the following factors:

• Backup coverage: Whether the service protects one computer, several devices, external drives, mobile media or a NAS.
• Recovery: Version history, deleted-file retention, point-in-time restore and physical restore options.
• Capacity: Unlimited versus capped storage and any speed, file-size or fair-use restrictions.
• Cost: Standard prices, renewal pricing, plan gating and charges for storage or add-ons.
• Ease of use: How much configuration is required and whether automatic defaults protect the files most people care about.
• Privacy: Encryption design, optional private keys and the consequences of losing account credentials.
• Consumer availability: The product must have a current personal or individual purchase path, not only an enterprise sales form.

We excluded SOS Online Backup because we could not verify a current consumer offer, IBackup because its present positioning is business and server focused and overlaps with IDrive, and Zoolz BigMIND Home because the current public purchasing path is not clear enough for a consumer recommendation. CrashPlan Essential was also removed after CrashPlan classified it as a legacy plan that is no longer available for new purchase.

Cloud Backup vs Cloud Storage and Sync

Cloud backup and cloud storage are not interchangeable. A dedicated backup service watches selected folders or the computer, uploads changed data automatically and retains older versions according to a backup policy. It is designed to help restore files after failure, deletion or corruption.

A sync service keeps the current version of a folder available across devices. That is convenient, but a deletion or unwanted edit may synchronize everywhere. Trash and file history can help, yet their retention windows may be short. pCloud and Internxt appear in this guide because they include backup functions, but buyers should understand that they remain storage and sync hybrids rather than complete system-backup replacements.

Cloud backup also differs from data recovery software. Backup helps when a usable copy already exists elsewhere. Recovery software tries to retrieve files from a drive or card after deletion or damage. A verified backup is more dependable than attempting recovery after the loss.

How to Choose a Cloud Backup Service

Count Computers and Devices First

A $9 unlimited plan can be excellent for one computer and expensive for four. Backblaze and Carbonite charge per computer. IDrive shares a storage allowance across multiple computers, while Jottacloud covers all devices for one user or five people on Home plans. Decide whether your household needs capacity, device count or both.

Measure the Library You Actually Need to Protect

Check the size of photo, video, document and project folders, then add external drives that must be included. Leave room for growth and historical versions. A 1TB plan is not enough for 900GB of current files once versions and new media accumulate.

Check Version and Deleted-File Retention

Unlimited storage does not automatically mean unlimited history. A service may keep deleted files for only 30 days or limit older versions. Choose a retention window long enough to notice a missing folder, corrupted catalog or accidental overwrite. Enable Backblaze's free one-year history manually if you select it.

Confirm External-Drive and NAS Rules

Some plans exclude external drives, require them to reconnect on a schedule or do not support network storage. Carbonite requires Plus or Prime for an external drive. Backblaze supports connected drives but not a NAS in its Personal plan. Arq and ElephantDrive are better starting points for network storage, subject to destination and model compatibility.

Plan the Restore Before the Backup

Consider how long it would take to download several terabytes on your connection. Backblaze and IDrive offer physical transfer options that can help with very large recoveries. Whatever you choose, restore a test folder before trusting the service with the only off-site copy.

Understand Private-Key Responsibility

Zero-knowledge or user-held-key encryption can reduce provider access to your files, but it changes account recovery. If the service cannot access the key, support may be unable to recover encrypted files after you lose it. Keep recovery information in a secure place separate from the computer being backed up.

What Buyers Should Check Before Paying

• Renewal price: A low first-year rate may rise at renewal. IDrive labels its annual discount as a first-year offer.
• Included cloud storage: Acronis Essentials is local-only, so Advanced is the lowest relevant Acronis cloud plan.
• Video rules: Carbonite Basic does not include automatic video backup.
• Unlimited-plan restrictions: Jottacloud reduces upload speed after 5TB and limits Personal to non-commercial use.
• Add-on costs: pCloud charges separately for its zero-knowledge encryption and extended history features.
• Commitment language: Confirm whether an annual plan is paid up front or billed monthly under a one-year commitment.
• Restore cost and speed: Check download limits, mailed-drive fees, return deadlines and any storage-provider egress charges.

How to Build a Safer 3-2-1 Backup

Cloud backup is strongest as one part of a 3-2-1 strategy: keep three copies of important files, on at least two types of storage, with one copy off site. A practical home setup can be:

1. The working photo and video library on the computer or main drive.
2. An automatic local backup on an external drive or NAS.
3. An encrypted cloud backup stored away from the home.

Do not leave the only local backup permanently vulnerable to the same theft, power event or malware as the computer. Rotate or disconnect an additional drive when practical. A photo backup device can provide another portable copy, but it should not be the only backup of irreplaceable memories.

Turn on multi-factor authentication where supported, save recovery keys securely, review backup alerts and test a restore at least a few times per year. A backup job completing successfully is useful evidence, but a verified restore is what proves the files can come back.

Final Verdict

Backblaze is the best cloud backup service for most people with one Windows PC or Mac. It offers unlimited capacity, automatic coverage, external-drive support and clear pricing, and users can enable one-year version history for free. It is the easiest recommendation for a large personal photo or video library on one main computer.

Choose IDrive when several computers and mobile devices need one shared plan. Choose Acronis True Image when full-system imaging and local backup matter as much as the cloud. Choose Arq when you want to control destinations and retention, or SpiderOakONE when zero-knowledge privacy is the priority.

Frequently Asked Questions

What is the best cloud backup service?

Backblaze is the best cloud backup service for most people with one Windows or Mac computer because it combines unlimited storage, automatic backup and simple pricing. IDrive is better for several computers, while Acronis True Image is better for full-system images.

What is the best cloud backup for photos?

Backblaze is a strong choice for a large photo library on one computer. IDrive works well when photos are spread across computers, external drives and phones. Jottacloud is useful for unlimited personal media across all devices, subject to reduced upload speed after 5TB.

Is unlimited cloud backup really unlimited?

Capacity may be unlimited while device, use or speed rules still apply. Backblaze and Carbonite cover one computer per subscription. Jottacloud's unlimited Personal plan covers all devices for one user but gradually reduces upload speed after 5TB and is not licensed for commercial files.

Does cloud backup protect an external hard drive?

Some services do, but the rules vary. Backblaze backs up connected external drives that are reconnected regularly. IDrive supports external-drive backup. Carbonite requires Plus or Prime. Confirm the plan and reconnection policy before depending on external-drive coverage.

Can cloud backup replace an external drive?

It should not be the only backup. A local drive restores large libraries quickly, while an off-site cloud copy protects against theft, fire or simultaneous damage at home. Using both is safer than relying on either one alone.

How often should I test a cloud backup?

Restore a small test folder after setup and repeat the test several times per year. Also test after changing computers, drives, passwords, encryption settings or backup destinations.
