What is the best cloud backup service?

The best cloud backup service depends entirely on whether you want a cheap, automated "set-it-and-forget-it" system for a single PC, or a highly customizable platform that can back up every device in your household.

Industry experts at PCWorld and PCMag consistently rank iDrive and Backblaze as the top choices for personal use.

Comparison of the Top Cloud Backup Services

What Real Users Say

A consensus among long-time tech users emphasizes the simplicity and reliability of choosing a dedicated backup route:

“Been using Backblaze's Computer Backup AND B2 products for several years now. I rely on them totally for all my cloud backup needs. ZERO problems, ZERO concerns, excellent support. The Backblaze Computer backup app has limitations, mostly by design, but if...”

Cloud Backup vs. Cloud Storage: A Crucial Distinction

Many people confuse cloud storage (like Google Drive, OneDrive, or Dropbox) with cloud backup.

• Cloud Storage: Designed to sync a specific folder across devices for real-time collaboration. If you accidentally delete a file, it often deletes everywhere.
• Cloud Backup: Designed to mirror your entire hard drive continuously in the background, keeping historical versions of your files so you can recover from hardware failure or ransomware attacks.

To help me narrow down the absolute best match for you, could you tell me:

• How many devices do you need to back up?
• Are you using Windows, Mac, or a mix of both?
• Roughly how much data (in Gigabytes or Terabytes) do you need to secure?

If you mean personal computer backup, my top pick right now is IDrive overall, with Backblaze as the better choice if you want maximum simplicity.

• 🏆 Best overall: IDrive — Best if you have multiple computers/phones or want more control. It supports PC, Mac, Linux, iPhone/iPad, Android, external drives, NAS, versioning, and archiving. PCWorld currently ranks it its best cloud backup overall.
• 🥇 Best for simplicity: Backblaze — Excellent for one Windows or Mac computer. It automatically backs up your data with unlimited storage and file size, including directly connected external drives.
• 🔐 Best for power users/security: Acronis Cyber Protect Home Office — worth considering if you want backup plus broader security and system-imaging features.
• 💼 Best for business: CrashPlan — particularly suited to endpoint backup for organizations.

My recommendation

If you're backing up one PC/Mac with lots of photos, videos, or documents, I'd choose Backblaze. It's hard to beat the combination of automatic operation and unlimited backup.

If you have several devices, want NAS/mobile backup, or want true archiving rather than simply mirroring your computer, I'd choose IDrive.

One important distinction: Dropbox, Google Drive, OneDrive, and iCloud are primarily sync/storage services, not full computer-backup replacements.

If you tell me what you're backing up (Windows/Mac/iPhone, number of devices, and roughly how many TB), I can tell you which service is the best value for your particular setup.

If you mean true cloud backup—automatically protecting your computer files so you can restore them after a drive failure, theft, ransomware, etc.—my top pick is IDrive for most people.

My picks

• 🥇 Best overall: IDrive — Excellent balance of price, storage, and features. Its Personal plan supports multiple computers and devices, continuous backup, external drives/NAS, disk imaging, and mobile devices. Current pricing lists 5 TB at $9.99/month monthly or $6.99/month on annual billing (promotional pricing can be lower for new customers).
• 🥈 Best for simplicity: Backblaze — Particularly good if you want to install it and basically forget about it. It's focused on straightforward computer backup rather than lots of extra cloud-storage features.
• 🥉 Best for power users: CrashPlan — Strong backup capabilities and customization, particularly if you're backing up computers in a small-business/professional environment.

What I'd choose

One important distinction: Google Drive, OneDrive, Dropbox, and iCloud are primarily cloud storage/synchronization services. They aren't necessarily a substitute for a dedicated backup system—especially against accidental deletion, ransomware, or a failed computer.

If you tell me Windows or Mac, how much data you have (e.g. 500 GB/2 TB/10 TB), and whether you want to back up one computer or several, I can tell you which service I'd personally choose and what it would cost.

IDrive is the best overall cloud backup service for most users because it allows you to back up unlimited devices into a single account, supports multiple operating systems, and offers the best balance of features and price per terabyte.

  • Standout Features : Full disk image backups, integrated anti-ransomware defenses, and flexible cloud-to-local hybrid scheduling.

If you would like to narrow this down, please let me know how many devices you need to back up, your approximate data storage size , and whether you prefer an automated hands-off tool or advanced security customization.

The best overall cloud backup service for most users is IDrive due to its incredible value and device flexibility, closely followed by Backblaze for those who want effortless, unlimited storage.

When choosing a service, ensure you differentiate between a cloud backup (which automatically archives your entire hard drive for disaster recovery) and cloud storage (like Google Drive or Dropbox, which are meant for manual file syncing and productivity).

Summary Comparison

To help you narrow down the perfect service, what operating system do you use (Windows, Mac, or Linux), and are you backing up a single computer or multiple devices?

If you mean true cloud backup—automatically backing up your computer so you can recover files after a drive failure, theft, ransomware, etc.—my top pick for most people is backblaze.com.

My picks

Why Backblaze: It's unusually straightforward: its Personal Backup plan is $99/year for unlimited data, including data on connected external drives, with automated/continuous backup.

When I'd choose IDrive instead: If you have several computers, want mobile-device backups, or want a large amount of cloud storage alongside backup. IDrive Personal currently offers 5 TB, 10 TB, 20 TB, and larger tiers, and can back up multiple computers and mobile devices.

One important distinction: Google Drive, OneDrive, and Dropbox are primarily cloud storage/sync services, not replacements for a dedicated backup system. Sync can propagate accidental deletions or corrupted files, whereas a proper backup service is designed for recovery.

Bottom line:

• Set it and forget it → Backblaze
• Lots of devices / lots of data → IDrive
• Already paying for Microsoft 365 → OneDrive
• Already deep in Google → Google One

If you tell me Windows/Mac, how much data you have (e.g. 500 GB/5 TB), and how many computers, I can tell you which one is the best value for your specific setup.

My picks

🏆 Best overall: IDrive

IDrive is particularly compelling if you have more than one device. It can back up PCs, Macs, Linux machines, iPhones, iPads, Android devices, external drives, and supported NAS systems under one account. It also offers snapshots/versioning and full-machine backup.

Its biggest advantage over Backblaze is flexibility: you're not limited to backing up one computer. IDrive also supports up to 30 previous versions of files and offers a physical-drive recovery service for large restores.

🥈 Best for simplicity: Backblaze

If you have one Windows PC or Mac and just want everything backed up automatically, I'd actually choose Backblaze.

It automatically backs up your data and connected external drives, with unlimited backup capacity and file size. Current pricing is $99/year for Personal Backup.

The tradeoff is that Backblaze Personal Backup isn't intended as a general cloud-storage/sync service, and NAS/network drives aren't included.

My quick recommendation:

• One computer → Backblaze
• Multiple computers/phones/NAS → IDrive
• Need full system images + security features → Acronis
• Business computers → CrashPlan

If you tell me how many computers/devices you have and roughly how many TB of data, I can narrow it down to the best plan and price for you.

The best overall cloud backup service is IDrive , offering the absolute best balance of value, multiple-device support, and comprehensive features. [1][2]

While IDrive is the top choice for most users, the perfect service depends on your exact setup, budget, and hardware. Below is the breakdown of the top industry-tested options. [1]

📊 Top Cloud Backup Services Compared

🔍 Deep Dive: The Top 3 Recommendations

1. IDrive — Best Overall Service

• Device Flexibility: Unlike standard services, a single subscription lets you back up every computer, phone, tablet, and network-attached storage (NAS) drive in your house.
• Deep Versioning: It stores up to 30 historical versions of your files indefinitely, protecting you against accidental overwrites.
• The Catch: If you go over your data limit, the overage fees can accumulate quickly. [1][2]

2. Backblaze — Best for Pure Simplicity

• Set and Forget: It offers a streamlined app that sits in the background and automatically uploads everything on your machine to the cloud.
• True Unlimited: There are zero caps on file sizes or total data amounts.
• The Catch: Licenses are strictly locked to one computer. It does not back up mobile devices or network drives under personal accounts. [1][2][3]

3. Acronis True Image — Best for Full System Recovery

• Complete Cloning: Instead of just saving folders, it creates complete mirror images of your hard drive so you can restore your entire operating system if your hardware crashes.
• Built-in Security: Includes built-in AI malware blocks to prevent ransomware from encrypting your files.
• The Catch: The software is resource-heavy and carries a much higher annual price tag. [1][2][3]

💡 Backup vs. Storage: A Quick Warning

Do not confuse cloud backup with cloud storage (like Google Drive, OneDrive, or Dropbox). Cloud storage tools are designed to sync a single folder for daily access and collaboration. Dedicated cloud backup services run silently in the background to replicate your entire computer structure so you can recover everything after a total system failure. [1][2][3][4]

To narrow this down, let me know:

• How many devices (PCs, Macs, phones) do you need to protect?
• Roughly how much data (in gigabytes or terabytes) do you have?
• Do you prefer a set-and-forget setup or advanced imaging features?

The "best" cloud backup service depends on whether you are looking to back up an entire computer automatically, manage huge quantities of data, or use a hybrid sync-and-share tool.

Note: True automated backup services (which mirror and protect your entire drive over time) differ from cloud storage/sync services like Google Drive or Dropbox, which are designed for active file collaboration rather than disaster recovery.

The top-rated cloud backup services categorized by their strengths include:

• IDrive Personal (Best Overall)
  • Pros: Allows unlimited devices (PCs, Macs, iPhones, Androids) under a single account, supports external hard drive backups, and keeps historical versioning of files indefinitely (until you run an archive cleanup).
  • Cons: Uses a tiered storage quota (e.g., 5TB or 10TB plans) rather than being completely unlimited.
  • Best for: Households or individuals with multiple gadgets, phones, and computers.
• Backblaze (Best for Unlimited Storage / Hands-Off Simplicity)
  • Pros: Offers truly unlimited data storage for a single computer at a flat yearly rate. It runs quietly in the background and doesn't make you calculate gigabytes or terabytes.
  • Cons: Restricted to one computer per license, doesn't back up mobile devices, and only retains deleted files for 30 days.
  • Best for: Power users with massive media libraries or heavy hard drives on one primary machine.
• pCloud (Best Hybrid / Lifetime Option)
  • Pros: Blends file syncing with robust backup features, fast upload speeds, and a rare lifetime subscription model so you can avoid recurring annual fees.
  • Cons: Zero-knowledge privacy encryption (pCloud Crypto) costs extra.
  • Best for: People who hate monthly/yearly subscriptions and want a virtual drive that works seamlessly across devices.
• Acronis Cyber Protect Home Office (Best for Power Users & Local/Cloud Hybrid)
  • Pros: Offers complete disk-image cloning, active ransomware defense, and flexible choices between local local-drive backups and cloud backups.
  • Cons: Can be pricey and has a steeper learning curve if you just want simple file archiving.
  • Best for: Tech enthusiasts and professionals who want absolute control over full system recovery.

If you can tell me how much data you need to back up and how many devices you want to protect, I can help you pick the most cost-effective service for your setup.

For most people, Backblaze is the best cloud backup service right now.

My picks

• 🥇 Best overall: Backblaze — Simple, automatic computer backup with unlimited data for $99/year. It backs up user-generated data, including connected external drives, without file-size restrictions.
• 🥈 Best for multiple devices: IDrive — Better if you want to back up several PCs/Macs plus phones and other devices from one account. Its Personal plan currently offers 5 TB, with promotional pricing of $6.99/month for the first year when billed annually.
• Best if you want a huge amount of data: Backblaze, because its personal computer backup is unlimited.

Which I'd choose

If your goal is simply “I want my computer automatically backed up so I don't lose my photos/documents if my hard drive dies,” choose Backblaze.

If you want backup + syncing across multiple computers/phones, I'd choose IDrive.

One important distinction: services like Google Drive, OneDrive, and Dropbox are primarily cloud storage/sync, whereas Backblaze and IDrive are designed specifically for backup. For protecting irreplaceable files, dedicated backup is generally what I'd recommend.

If you tell me what devices you want to back up (Windows/Mac/iPhone/Android), roughly how many TB you have, and whether you want to back up external drives, I can tell you which one is the best fit and cheapest for you.
