Backblaze Personal Backup

Description

Assessment Status: Research-Based Assessment

Quick Editorial Summary

Backblaze Personal Backup is an unlimited cloud backup service for a single Mac or PC, built around a simple idea: install it once, and it quietly backs up every file in the background without asking you to pick folders or worry about storage caps. It’s aimed at people who want a “set it and forget it” safety net against hard drive failure, accidental deletion, theft, or disaster, rather than a full file-sync or sharing tool.

What Backblaze Personal Backup Does

Once installed, Backblaze automatically finds and continuously backs up the files on a computer’s internal drives (and attached external drives) to Backblaze’s own data centers, with no cap on how much data can be stored. Backups run in the background as files change, and users can restore individual files, whole folders, or an entire computer through a web browser, the Backblaze mobile app, or by having Backblaze mail a physical USB drive containing the data.

Who It May Suit

This plan tends to suit individuals and households who want a low-effort backup for one computer at a time, people who have been burned before by a drive failure or accidental deletion and want a passive safety net, and anyone who would rather pay a flat monthly rate for unlimited storage than track how many gigabytes they’re using.

How It Works

After creating an account and installing the desktop app, Backblaze begins backing up data automatically using default settings, with no need to manually select files or folders. Files are encrypted before they leave the computer and remain encrypted in Backblaze’s data centers. Users can optionally set a private encryption key that only they know, which Backblaze says makes it impossible for even Backblaze staff to access the backed-up files. Restores can be performed by downloading files through a browser, using the mobile app, or requesting a mailed hard drive, which can be returned within 30 days for a refund of the drive fee.

Key Features

• Unlimited backup storage for one computer, with no file-size or file-type restrictions
• Automatic, continuous backup that runs in the background
• Optional private encryption key for extra control over data access
• Two-factor verification (SMS and time-based one-time codes)
• Restore options: web-based download, mobile app, or mailed USB/hard drive
• Locate a lost or stolen computer through Backblaze’s tools
• Ability to share individual backed-up files with others
• Native Mac and Windows applications

Important Limitations

Backblaze Personal Backup covers one computer per license, so protecting multiple devices means paying for multiple subscriptions. It is a backup tool rather than a real-time file-sync or collaboration service, and by default it does not offer unlimited free web restores of very large amounts of data in a single request. There is no permanent free tier, only a 15-day trial, so ongoing protection requires a paid plan. As with any cloud backup service, the safety of a private encryption key is the user’s own responsibility; losing it can mean losing access to backed-up files.

Privacy and Security Considerations

Backblaze states that files are encrypted before leaving a user’s computer and remain encrypted at rest in its data centers, and that data centers use physical security measures such as staffed monitoring and biometric access controls. The optional private encryption key adds a layer where, according to Backblaze, even its own staff cannot decrypt a customer’s files without that key. Two-factor authentication is available to help protect the account itself. As with any backup or cloud storage provider, no service can promise complete protection against every possible failure, and Backblaze does not claim to prevent all forms of data loss on the user’s own device before it’s backed up.

Supported Platforms and Devices

According to Backblaze, Personal Backup offers native applications for Mac and Windows computers, along with web-based and mobile access for managing and restoring backups.

Pricing and Plan Notes

Backblaze lists Personal Backup at a monthly rate, with lower effective monthly rates available when paying annually or biennially. Because pricing, promotional terms, and billing cycles can change, readers should confirm the current rate directly on Backblaze’s official pricing page before subscribing. A 15-day free trial is available and does not require a credit card.

Free or Lower-Cost Alternatives

Backblaze does not offer a permanent free backup tier, so people who only need to protect a small amount of data may find free-tier allowances from general-purpose cloud storage services (used manually rather than as automatic full-system backup) sufficient for lighter needs. Those specifically wanting unlimited, automatic single-computer backup, however, will generally need to compare Backblaze’s paid plan against similarly priced competitors.

Who It Is Not Ideal For

Backblaze Personal Backup may not be the best fit for people who need to back up many computers under one simple plan, since pricing is per computer, or for users who want real-time file syncing and collaborative sharing across devices rather than a backup-and-restore model. It’s also a lower priority for anyone unwilling to pay an ongoing subscription for storage, since there is no free long-term plan.

Our Editorial View

Backblaze Personal Backup’s appeal is its simplicity: unlimited storage for one computer at a predictable price, with backups that run automatically once installed. Because Nesswick has not independently tested Backblaze hands-on, this assessment reflects Backblaze’s own published claims rather than firsthand restore-speed or support experience, and readers should verify current features and pricing directly with Backblaze before subscribing.
