Losing important files can happen for many reasons. A hard drive can fail, a laptop can be stolen, malware can damage files, or an accidental deletion can remove something you still need.
A cloud backup service provides an additional copy of your data in an off-site location, helping reduce the risk of losing important files when something happens to your computer or local storage.
However, cloud backup is not the same as ordinary cloud storage. Services such as Google Drive, Dropbox, and OneDrive are often designed around file syncing and sharing, while dedicated backup services are built primarily to protect computers, devices, and larger sets of data.
In this guide, we compare some of the best cloud backup services in 2026, including IDrive, Backblaze, Carbonite, and Acronis, to help you find a solution that fits your devices, storage needs, budget, and recovery requirements.

What Is Cloud Backup?
Cloud backup is a service that automatically or manually copies your files and other data to remote servers operated by a cloud provider.
Instead of keeping your only copy on a laptop, desktop, external drive, or other local device, cloud backup gives you an additional copy stored away from the original device.
Depending on the service, you may be able to back up:
- Documents
- Photos
- Videos
- Music
- Projects
- Applications and system data
- External hard drives
- Mobile device data
- Servers
- Microsoft 365 data
- Google Workspace data
- NAS devices
The exact features depend on the provider and plan.
Cloud Backup vs. Cloud Storage
Cloud backup and cloud storage can look similar, but they serve different purposes.
Cloud storage is generally designed to store, sync, access, and share files across devices.
Cloud backup is primarily designed to create recoverable copies of data so you can restore files after deletion, hardware failure, malware, or another data-loss event.
For example, a cloud storage service may be useful when you want to access a document from your laptop and phone. A dedicated backup service is more appropriate when you want an automated copy of your computer that can be restored after a serious problem.
This distinction is important when choosing a service.
Best Cloud Backup Services in 2026
1. IDrive, Best for Multiple Devices
IDrive is one of the most flexible choices for users who need to back up multiple computers and devices from one account.
Its current plans support backup for PCs, Macs, Linux systems, iPhones, iPads, and Android devices, depending on the plan. IDrive also supports external drives, NAS devices, servers, and several business data sources.
Why IDrive Stands Out
IDrive is particularly useful when you do not want to manage separate backup subscriptions for every computer.

- Unlimited data backup
- Continuous automated backup
- Backup for computer data
- Connected external drive backup
- Web-based access
- File restoration
- Native Windows and Mac applications
- Two-factor authentication
- Optional private-key encryption
Backblaze also provides different restore options, including web-based restores and a mailed-drive restoration option.
What to Watch Out For
Backblaze Personal Backup is focused on computer backup rather than being an all-purpose multi-device backup platform.

3. Carbonite, Best for Automatic Unlimited Backup
Carbonite focuses on automatic cloud backup for individuals, families, and businesses.
Its current personal plans include Basic, Plus, and Prime. Carbonite lists unlimited cloud backup on these personal plans, while the number and type of devices or external drives covered vary by plan.
Why Carbonite Stands Out
Carbonite is designed around automatic backup rather than manual file management.
Depending on the plan, features include:
- Automatic cloud backup
- Unlimited backup
- Encrypted backup
- Document backup
- Photo and music backup
- File recovery
- Protection against certain malware-related data loss
- External hard drive backup on eligible plans
- 256-bit encryption
The current personal pricing shown by Carbonite starts at $95.99 per year before the displayed promotional discount for the Basic plan. Plus and Prime plans provide additional features and external-drive coverage.
What to Watch Out For
The differences between Carbonite plans matter.
For example, external hard drive coverage is included with Plus and Prime rather than the Basic plan shown on its current personal pricing page.
You should therefore compare the plans based on what you actually need to protect instead of choosing the cheapest option automatically.
Best for: Individuals and families looking for automatic cloud backup with unlimited backup on supported personal plans.

4. Acronis True Image, Best for Advanced Backup and Recovery
Acronis True Image is aimed at users who want more than straightforward file backup.
The current Acronis product line includes backup, disk imaging, cloning, recovery, cloud backup, and additional security features. Acronis True Image was formerly known as Acronis Cyber Protect Home Office.
Why Acronis Stands Out
Acronis provides several backup approaches, including:
- File and folder backup
- Full image backup
- Disk cloning
- Backup scheduling
- Backup versioning
- Cloud backup
- Local backup
- Microsoft 365 backup
- Mobile backups
- Recovery tools
- Anti-malware features on applicable plans
Acronis also offers a Survival Kit feature designed to help with recovery and disaster scenarios.
For individuals, Acronis currently lists Essentials, Advanced, and Premium plans. Its comparison page shows starting prices of $49.99, $72.99, and $124.99 per year respectively, although prices can vary by region, subscription, and promotion.
What to Watch Out For

How to Choose the Right Cloud Backup Service
Choosing a backup service becomes easier when you start with the data you need to protect.
1. How Many Devices Do You Need to Back Up?
Start by counting your computers and other devices.
If you only have one computer, a simple service such as Backblaze may be enough.
If you have several computers, smartphones, external drives, or NAS devices, look for a service that supports multiple device types under one account.
2. How Much Data Do You Have?
Storage capacity can have a major effect on the price.
Check the size of:
- Documents
- Photos
- Videos
- Work files
- External drives
- Projects
- Existing backups
Do not choose a plan based only on the amount of data you have today. Consider how quickly your data is likely to grow.
3. Do You Need Unlimited Backup?
Some services offer unlimited backup under specific plans, while others use fixed storage limits.
Unlimited plans can be convenient if you have large amounts of data, but they may come with restrictions regarding the number of devices or supported storage types.
Always check the details rather than assuming “unlimited” means unlimited everything.
4. Do You Need File Versioning?
File versioning allows you to recover an earlier version of a file.
This can be useful when a file is accidentally overwritten or becomes corrupted.
Check how many versions the service keeps and how long those versions remain available.
5. Do You Need Local and Cloud Backup?
Cloud backup does not necessarily replace local backup.
For important data, having more than one backup location can provide additional resilience.
Some services, including IDrive and Acronis, offer combinations of local and cloud backup capabilities.
6. How Easy Is Recovery?
Backup is only useful if you can recover your data when you need it.
Look at:
- Web restoration
- Desktop restoration
- Mobile access
- Full computer recovery
- Large-data recovery options
- Restore speed
- Version history
For large backups, the available recovery method can be just as important as the backup itself.
Is Cloud Backup Worth It?
For many users, cloud backup can be worthwhile because computers and local storage devices can fail.
A laptop can be damaged, a hard drive can stop working, or files can become inaccessible because of malware or accidental deletion.
A cloud backup provides an additional copy stored away from the original device.
However, cloud backup should not automatically be treated as a complete replacement for every other backup method.
A practical backup strategy may combine:
- Local backup
- Cloud backup
- An additional offline or separate copy for particularly important data
The right approach depends on the importance of your files, how quickly you need to recover them, and how much downtime you can tolerate.
Cloud Backup Security and Privacy
Security should be one of the first things you evaluate when choosing a cloud backup provider.
Look for features such as:
- Encryption during transfer
- Encryption while data is stored
- Two-factor authentication
- Private or user-controlled encryption options
- Secure account recovery
- Access controls
- Version history
- Ransomware-related recovery features
However, no backup service can eliminate every security risk.
Your account password, authentication settings, device security, and backup configuration also matter.
For sensitive business or personal information, review the provider’s current security documentation and privacy policies before uploading data.

Frequently Asked Questions
What Is the Best Cloud Backup Service in 2026?
There is no universal winner. IDrive is strong for multiple devices, Backblaze is focused on simple computer backup, Carbonite emphasizes automatic unlimited backup on supported plans, and Acronis provides more advanced backup and recovery features.
Is Cloud Backup the Same as Cloud Storage?
No. Cloud storage is generally focused on storing, syncing, accessing, and sharing files. Cloud backup is designed primarily to create recoverable copies of data.
Is Unlimited Cloud Backup Really Unlimited?
Not always in every sense. A provider may offer unlimited storage while still limiting the number of devices, supported data sources, or other features. Always check the specific plan terms.
How Often Should I Back Up My Computer?
For important files, automated and frequent backups are generally preferable to relying on occasional manual backups. The appropriate schedule depends on how often your data changes and how much data loss you could tolerate.
Can Cloud Backup Protect Against Ransomware?
Cloud backup can provide recoverable copies that may help with certain ransomware-related data-loss situations, but it should not be treated as a guarantee against ransomware. Security also depends on account protection, backup configuration, version history, and the provider’s recovery capabilities.
Should I Use Cloud Backup and an External Hard Drive?
Using both can provide additional protection. An external drive can provide a local copy for faster recovery, while cloud backup provides an off-site copy that is not stored in the same physical location as your computer.
How Much Cloud Backup Storage Do I Need?
Start by calculating the amount of data on the devices and drives you want to protect. Then consider future growth and whether you need multiple versions of files.
Is Cloud Backup Worth Paying For?
For important personal, business, or creative files, paying for automated backup can be worthwhile because recreating lost data can be much more expensive than the backup subscription itself.
Bottom Line
The best cloud backup service is not necessarily the one with the largest storage limit or the longest feature list.
Choose a service based on your devices, data volume, recovery needs, security requirements, budget, and long-term backup strategy.
A reliable backup plan gives you something more valuable than storage. It gives you another way to recover your important data when your original copy is no longer available.
