Does Backblaze back up external hard drives connected to my workstation?

Yes, Backblaze automatically includes USB and FireWire connected external hard drives in its personal backup plan at no extra charge, provided they are reconnected to the computer at least once every 30 days.

How does ransomware recovery work on Dropbox compared to Backblaze?

Dropbox allows you to roll back entire folders or your entire account to any point in time within your retention window (30 to 180 days). Backblaze allows you to restore previous file versions or revert snapshots up to 1 year or indefinitely depending on your history settings.

Will continuous background backup slow down my home office internet?

Both services allow you to limit upload speeds and schedule backup windows. By default, they throttle background processes so you can work and video conference without noticeable lag, though initial syncs may take time.

Can I use Dropbox as a complete system backup replacement?

No. Dropbox is a file synchronization service that only mirrors designated sync folders. It does not back up operating system files, applications, hidden directories, or system states the way a dedicated backup tool like Backblaze does.

Backblaze vs. Dropbox for Home-Office Professionals: Comprehensive Decision Report

Question: Should a home-office professional back up local workstation files using cloud backup service 'Backblaze' or file synchronization service 'Dropbox', considering continuous background backup speed limits, file version history retention duration, and ransomware recovery ease?

Prepared by the ChoiceScore Research Desk · Editor-approved for the curated library · Reviewed July 26, 2026

Recommended Choice Score: 82/100

Direct answer

For a home-office professional prioritizing complete, automated workstation protection with unlimited version retention and low fixed pricing, Backblaze is the superior choice, whereas Dropbox remains better suited for real-time multi-device file syncing and active collaboration.

Summary

Choosing between Backblaze and Dropbox for a home-office workstation depends entirely on whether your primary objective is comprehensive disaster recovery or agile file accessibility. Backblaze operates as a set-and-forget cloud backup solution that automatically copies your entire local drive—unlimited by file size or storage capacity—keeping deleted and historical file versions indefinitely for an annual flat fee. Conversely, Dropbox excels as a file synchronization and sharing platform that keeps active working folders mirrored across multiple devices with sophisticated collaboration tools, but limits extended version history depending on your subscription tier and charges per active workstation. When evaluating background backup speeds, file history retention, and ransomware recovery ease, both platforms provide robust safeguards, but target distinctly different operational workflows.

Choice Score breakdown

Cost Efficiency & Storage Limits 90/100 — Backblaze offers unlimited storage per computer for a flat annual fee, unlike tiered per-gigabyte or per-user sync models.
Backup Speed & Throttling Control 75/100 — Backblaze throttles background processing to prevent resource hogging, while Dropbox prioritizes active sync bandwidth.
Version History & Ransomware Recovery 85/100 — Backblaze retains file versions indefinitely (or up to 1 year extended), while Dropbox relies on explicit version tiers.
Multi-Device Collaboration & Sync 70/100 — Dropbox dominates active multi-device file editing, whereas Backblaze is strictly single-workstation backup.

Best for / Not best for

Best for

Home-office professionals with a single primary desktop or laptop containing large archives
Users seeking set-and-forget automated backup without managing folder selections
Professionals requiring indefinite or long-term file version retention for compliance or accidental overwrites

Not best for

Users needing to sync identical active working folders across three or more different computers in real time
Teams or individuals who frequently collaborate and share granular file links directly from their desktop explorer
Linux workstation users (as Backblaze Personal Backup lacks robust official Linux client support)

Scenarios

Catastrophic Workstation Failure (Optimistic) (75% likely)
Your main office computer experiences total motherboard and drive failure, requiring a full system state and data restoration.
Ransomware Attack & Mass File Encryption (Likely) (60% likely)
Malware infects your workstation, encrypting thousands of working documents and syncing the corrupted files instantly to the cloud.
Multi-Device Active Collaboration Workflow (Alternative) (90% likely)
You frequently switch between a home desktop, a portable laptop, and a tablet while editing shared active client files.

Pros & cons

Pros

Backblaze offers unlimited storage capacity with no file size or total volume restrictions on personal plans.
Backblaze provides indefinite version history retention options, preventing data loss from delayed ransomware discovery.
Dropbox delivers exceptional real-time multi-device synchronization and peer-to-peer file sharing capabilities.
Both services feature automated background operation that minimizes active manual intervention for busy professionals.

Cons

Backblaze is licensed strictly per computer; external drives must remain connected every 30 days to prevent deletion.
Dropbox caps standard storage quotas (e.g., 2TB) and charges significantly more for higher volume requirements.
Initial full backup seeding for large local workstation archives (1TB+) can take weeks depending on home internet upload limits.
Backblaze does not support granular single-folder selection on personal plans; it defaults to backing up the entire user drive.

Assumptions

Workstation Count: 1 Primary Workstation — Backblaze Personal Backup is licensed strictly per computer, making single-workstation analysis the baseline.
Internet Connection: 50 Mbps symmetric fiber — Used to evaluate background upload speed impact during normal home-office working hours.
Storage Volume: 1.5 TB local data — Exceeds standard free tiers and tests cloud scalability.

Practical next steps

Audit your home-office storage needs by calculating your total local file volume and determining if you manage one or multiple computers.
Evaluate whether your primary goal is active multi-device collaboration (Dropbox) or comprehensive disaster recovery (Backblaze).
Install your chosen client software and configure bandwidth throttling settings to prevent interference with video calls and daily telecommuting tasks.
Verify encryption settings, enable two-factor authentication (2FA) on your cloud account, and test file restoration procedures with a small sample folder.
