Best Online Backup Service
The 10 best online backup services in 2026, ranked by storage, speed, and reliability.
How This List Was Built
Online backup differs from sync: it protects your entire drive automatically. We compared documented backup speed, restore reliability, encryption, and price across the leading continuous-backup services.
What Drives the Ranking
Backup reliability
A backup service that fails silently is worse than none — restore testing is the real test.
Encryption
Zero-knowledge encryption keeps your backups private from the provider.
Price for capacity
Unlimited versus per-TB pricing changes the math by data volume.
Why #Personal Backup Took the Top Spot
iDrive Personal Backup (Personal Backup) wins because its flat ~$70/yr pricing with generous capacity and solid clients covers most home users — the best value in true backup. Backblaze (Mini tier listed at ~$80) offers unlimited backup for one computer; pCloud (Personal Cloud, ~$200 lifetime) adds zero-knowledge encryption with a lifetime option. The honest answer: Backblaze for unlimited simplicity, iDrive for capacity value, pCloud for lifetime zero-knowledge.
When the ranking flips: Backblaze overtakes iDrive for users with huge data who want unlimited backup without capacity math.
When the Ranking Changes
- Capacity value — pick iDrive Personal Backup Generous capacity at flat pricing.
- Unlimited simplicity — pick Backblaze Unlimited backup for one computer.
- Zero-knowledge lifetime — pick pCloud Lifetime encryption option at ~$200.
What We Left Out
- Sync services (Dropbox, Drive) were excluded — not true backup.
- Services without versioning were excluded.
How This Was Researched
This ranking is based on a structured review of official product documentation, published specifications, current pricing, and feature analysis — the same methodology ToolStep describes on the /how-we-test/ page. We do not claim hands-on testing that did not happen.
Based on official product documentation as of June 2026.

FAQ
What is the best online backup service?
Backblaze Personal Backup at $70/year is the best overall with unlimited backup for one computer and a locate-and-ship restore option. For multiple devices, IDrive Mini at $80 offers 5TB.
What is the difference between cloud sync and backup?
Cloud sync (like Dropbox) mirrors folders across devices. Online backup protects your entire drive, including files not in a synced folder. Backblaze and IDrive are true backup services.
Is unlimited backup really unlimited?
Backblaze and Carbonite offer unlimited backup, but they throttle large initial backups and limit external drive sizes. Read the fair use policy. For most users, 5TB with IDrive is more practical.
How long does online backup take?
The initial backup depends on your upload speed and data size. A 500GB backup takes about 2 weeks on a 50Mbps connection. Incremental backups after that are fast, syncing only changed files.
Can I backup external drives online?
Yes. Backblaze, IDrive, and CrashPlan all support external drives. Backblaze includes one external drive per license. IDrive supports unlimited external drives with your 5TB quota.
