What Is Backblaze Personal Backup? Complete Review & Guide (2026)

What Is Backblaze Personal Backup?

Backblaze Personal Backup is a consumer-focused cloud backup service that provides unlimited storage for Mac and PC computers at a flat rate of $9 per month. The service runs continuously in the background, automatically backing up files from personal computers without user intervention. Unlike many competitors that impose storage caps or charge per gigabyte, Backblaze Personal Backup truly offers unlimited storage for a single computer.

The service targets individual users and families who want comprehensive backup protection without the complexity of configuring storage quotas or worrying about usage limits. Backblaze has been operating since 2007 and positions this service as their entry-level offering alongside their B2 cloud storage platform for developers and businesses.

Key Features and Specs

Backblaze Personal Backup delivers several core capabilities that distinguish it from other backup solutions:

Unlimited Storage: The service backs up all data on a single computer with no storage limits, file size restrictions, or bandwidth throttling. Users can backup terabytes of data for the same monthly fee.

Continuous Backup: The client software monitors file changes and uploads new or modified files automatically. This happens in the background without requiring scheduled backup windows or manual initiation.

Cross-Platform Support: Native clients are available for both macOS and Windows, supporting all recent operating system versions.

File Versioning: Backblaze retains previous versions of files for 30 days by default. Users can access and restore earlier versions of documents that have been modified or corrupted.

Military-Grade Encryption: Data is encrypted both in transit and at rest using AES-256 encryption. Users can optionally set a private encryption key for additional security, though this prevents Backblaze support from assisting with password recovery.

Mobile Access: iOS and Android apps allow users to browse and download backed-up files remotely, though mobile devices themselves are not backed up.

Restore Options: Users can restore files through the web interface, mobile apps, or by requesting physical drive shipment for large data recoveries.

Backblaze Personal Backup Pricing

Backblaze Personal Backup uses straightforward pricing with no hidden fees or usage tiers:

• Monthly: $9 per month per computer
• Annual: $99 per year per computer (saves $9 annually)
• Two-year: $189 per two years per computer (saves $27 over monthly)

Each license covers one computer only. Households with multiple computers need separate licenses for each device. The service includes unlimited storage, bandwidth, and file transfers at these prices.

For large data recoveries, Backblaze offers optional services:

• USB Drive Restore: $99 for up to 256GB delivered on USB drive
• Hard Drive Restore: $189 for up to 8TB delivered on external hard drive

These physical restore options can be returned within 30 days for a refund, effectively making them free data recovery services.

Performance and Locations

Backblaze operates data centers primarily in the United States and has expanded internationally with facilities in Europe. The company does not publish specific data center locations for security reasons, but users can expect their data to be stored in facilities geographically close to their region.

Upload speeds depend largely on the user's internet connection and Backblaze's bandwidth allocation algorithms. The service prioritizes continuous operation without impacting computer performance, so initial backups of large datasets can take several days or weeks to complete. Subsequent backups of changed files typically complete within hours.

The service is optimized for personal computer backup rather than low-latency access or high-throughput applications. File downloads through the web interface are suitable for occasional file recovery but not intended for frequent access patterns.

Backblaze does not publish specific uptime SLAs for Personal Backup, though the company reports high availability across their infrastructure. Users should expect occasional maintenance windows and service interruptions typical of consumer backup services.

Who Is Backblaze Personal Backup Best For?

Backblaze Personal Backup serves specific use cases particularly well:

Individual Users with Large Data Collections: Photographers, videographers, and content creators who generate terabytes of data benefit most from the unlimited storage model. The flat monthly fee makes it economical for users with extensive media libraries.

Home Users Seeking Simplicity: The service works well for non-technical users who want comprehensive backup protection without configuring complex retention policies or storage quotas.

Mac and PC Owners: The service specifically targets personal computer backup, making it ideal for traditional desktop and laptop users rather than mobile-first users.

Budget-Conscious Users: At $9 per month, Backblaze Personal Backup offers one of the lowest per-month costs for unlimited cloud backup among major providers.

The service is less suitable for:

• Server administrators needing enterprise backup features
• Users requiring frequent file access or sync functionality
• Mobile-first users who primarily work from tablets and smartphones
• Organizations needing compliance features or extended retention policies

Pros and Cons of Backblaze Personal Backup

Pros:

• True Unlimited Storage: No hidden caps or fair use policies restrict backup size
• Simple Pricing: Flat monthly fee with no overage charges or complex tiers
• Set-and-Forget Operation: Continuous background backup requires minimal user interaction
• No File Size Limits: Can backup individual files of any size, including large video projects
• Physical Restore Options: USB and hard drive shipping provides fast recovery for large datasets
• Strong Encryption: AES-256 encryption with optional private key management

Cons:

• Personal Computers Only: Cannot backup servers, NAS devices, or business infrastructure
• Limited Version History: 30-day retention for file versions may be insufficient for some users

• Limited Business Features: No team management, compliance reporting, or enterprise integrations

Backblaze Personal Backup Alternatives

Carbonite Safe: Offers unlimited personal backup starting at $6 per month but includes more restrictive bandwidth limitations and excludes certain file types by default. Carbonite provides broader device support including external drives.

IDrive Personal: Provides 5TB of storage for $79.50 per year with support for multiple devices and platforms. While not unlimited, IDrive includes file sync capabilities and broader device compatibility including mobile backup.

Crash Plan for Small Business: Targets small businesses and power users with unlimited backup for $10 per month per device. Offers more advanced features like extended version history and administrative controls, though at a slightly higher price point.

Final Verdict

Backblaze Personal Backup delivers on its core promise of unlimited computer backup at a competitive price point. The service excels for users who prioritize simplicity and have large amounts of data to protect. The $9 monthly fee represents excellent value for users with terabytes of files, particularly creative professionals with extensive media libraries.

However, the service's focus on personal computer backup limits its applicability. Users managing multiple devices, requiring file sync functionality, or needing business-grade features should consider alternatives. The 30-day version history may also be restrictive for users who need longer-term file recovery capabilities.

For individual Mac and PC users seeking reliable, unlimited backup protection without complexity, Backblaze Personal Backup provides a solid solution that has proven reliable over many years of operation.
