What Backblaze Is and What It Replaces
Backblaze is a cloud backup service designed as a simpler, privacy-focused alternative to Carbonite. Both are managed services that automatically back up your files from Windows or macOS computers. However, while Carbonite has long been known for its feature-rich but complex pricing and unclear data practices, Backblaze offers an easier-to-understand model with stronger emphasis on user control and privacy.
The Privacy Model
Backblaze protects your data through optional private encryption key support. With this option enabled, you generate and manage your own encryption key — meaning only you can decrypt the files stored in Backblaze’s cloud. This is a form of zero-knowledge privacy: even if someone accessed the service's servers, they would not be able to read your data without your key.
Carbonite does offer encryption, but it typically uses server-side encryption where the company may retain access keys or fail to allow users full control over their own decryption process. Backblaze also operates in a jurisdiction (the United States) that is part of international privacy agreements, though its transparency and long-standing history make it more trusted by many users.
Neither service uses ad-tracking on the user's device — both are focused purely on backup functionality.
What You Actually Get / Key Features
- Unlimited backups per computer: One flat price covers all your data, with no file limits or storage caps.
- Optional private encryption key: Users can choose to encrypt their backups using a personal key they control — ensuring zero-knowledge privacy.
- Restore options: Files can be restored via download from the web interface, or for large amounts of data, Backblaze will mail you a physical drive with your backup.
- Native apps: Full support for Windows and macOS with no need to install third-party tools or use command-line interfaces.
- Long-established company: Backblaze has been in operation since 2007, known for transparency about its operations and pricing.
Cost vs Carbonite
Backblaze charges a flat rate of approximately $9 per month per computer. This is typically simpler and more affordable than Carbonite’s tiered plans, which can vary in price depending on the number of devices or features included (such as file versioning). With Backblaze, you pay one predictable amount for unlimited storage and automatic backups — no hidden fees or data limits.
Who It's For and Who Should Not Switch
Backblaze is ideal for:
- Users who want a simple, transparent pricing model with no file or storage limits.
- Those who value strong privacy options like private encryption key support.
- People looking to simplify their backup without managing servers or complex software.
Backblaze may not be the best choice for:
- Users who require advanced features such as real-time collaboration, shared backups, or cloud storage beyond just backup functionality (e.g., file syncing).
- Those needing self-hosted solutions — Backblaze is a fully managed service and cannot be run on your own infrastructure.
How to Get Started
To begin using Backblaze, visit the official site at Backblaze.com. Sign up for an account and download the native macOS or Windows app. The initial backup will start automatically — you can also choose to enable private encryption key support during setup if desired.
Once your data is backed up, you’ll have full access through the web interface or via file restore options. Switching from Carbonite involves deactivating that service and using Backblaze as your new primary backup destination.
