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.

  • No AI-written content. Every review is created through editorial research and product analysis. We use AI tools for research assistance only, never for generating review conclusions or ratings.

  • Product documentation review: We analyze official manufacturer specs, product documentation, and published technical information.
  • Feature evaluation: We assess features against the product's intended use case and target workflow.
  • Pricing comparison: We compare the product against at least two direct competitors in the same price tier.
  • Workflow assessment: We evaluate how the product fits into real-world home office and professional workflows based on published capabilities.
  • Published information synthesis: We aggregate publicly available information including manufacturer specs, changelogs, and public documentation to form our assessment.
  • Reader feedback integration: We monitor reader comments and warranty claim patterns. If a product shows widespread failure, we update our recommendation.
