Backblaze is a cloud backup service used by individuals, home-office users, and creative professionals around the world on Windows and Mac. It provides unlimited automatic backup for a single computer, external drive support, version history management, web-based file recovery, and a physical drive delivery option for large-scale restores, all within a minimal interface designed for straightforward, continuous data protection. This review takes a neutral and practical look at what the software does well, where it performs consistently, and who is most likely to find it useful.

Backblaze Personal Backup is one of the most recognized names in consumer cloud backup, built around a clear and simple proposition: unlimited storage for one computer at a flat monthly or annual rate. There are no file type restrictions, no size caps, and no decisions to make about what gets backed up — the software backs up the entire computer by default, with options to exclude specific folders if desired.

This approach removes one of the most common failure points in backup strategies: users forgetting to include important folders, or avoiding backup altogether because they are unsure how to configure it. For everyday computer users who want comprehensive protection without complexity, the unlimited and automatic model is directly suited to that need.

This review examines how Backblaze performs across its core functions, what its pricing structure looks like, and which users are best positioned to benefit from it.

What Is Backblaze

Backblaze Personal Backup is a cloud backup application for Windows and Mac that automatically backs up the entire contents of a computer — including documents, photos, videos, music, and desktop files — to Backblaze’s cloud infrastructure in the background. The service operates on an unlimited storage model, meaning there are no caps on how much data can be backed up per license regardless of file size or total volume. Each license covers one computer.

The software installs as a background service and begins backing up immediately after setup. By default, it backs up all files on the computer except for operating system files, applications, and a small number of excluded file types, which can be adjusted through the settings. Files attached to the computer via external USB drives are also included in the backup by default, extending coverage to external storage without additional configuration.

Version history is maintained for backed-up files, allowing users to retrieve earlier states of documents or recover deleted files within the retention window. The standard retention period is one year, with an extended version history option available for users who need longer coverage. Recovery options include downloading individual files or folders through a web browser, generating a zip file of selected content, or requesting a physical drive to be shipped containing the backed-up data — a practical option for users who need to restore a large volume of files without waiting for a full download.

Key Features

Unlimited Storage per Computer: Backblaze backs up the entire computer without storage limits, file size restrictions, or file type exclusions beyond a small default list. In tested scenarios, large video files, RAW photo archives, and mixed-content folders were all backed up without hitting limits or requiring manual inclusion. This removes the need to decide what is worth backing up based on size or quota.

Automatic Background Backup: The service monitors the computer for new and changed files continuously and uploads them to Backblaze’s cloud infrastructure without requiring user action. In tested scenarios, file changes were captured and queued for upload promptly, and the background process ran without noticeable impact on system performance during standard computing tasks.

External Drive Backup: USB-connected external drives are included in the backup scope by default. In tested scenarios, files on connected external drives were backed up alongside the main computer’s content without requiring separate configuration. Drives that are not connected for an extended period are flagged in the interface, and their backed-up data is retained for 30 days after the last connection before being removed from the backup set.

Version History and Deleted File Recovery: Backblaze retains previous versions of files and deleted items for one year by default, with an extended history option available. In tested scenarios, locating and downloading previous versions of specific files through the web restore interface was straightforward, and the process did not require technical knowledge to complete.

Web-Based and Physical Restore Options: Files can be restored by downloading them individually or as a zip file through the Backblaze web interface. For users who need to restore a very large volume of data, Backblaze offers a physical drive delivery service — a USB drive or hard drive containing the backed-up data is shipped to the user, which can then be returned to Backblaze for a refund of the shipping cost.

Encryption: Data is encrypted in transit using TLS and at rest on Backblaze’s servers. Users can optionally configure a personal encryption key for an additional layer of privacy, which prevents Backblaze from being able to access the stored data. In tested scenarios, configuring a personal key was available during setup and applied to all subsequently backed-up data.

Performance Review

Backup Speed and Consistency In tested scenarios, Backblaze’s background backup ran consistently without requiring manual activation. File changes were captured and uploaded reliably throughout the day, and the process did not produce noticeable slowdowns during standard computer use including document editing, web browsing, and media playback. Upload speed was naturally subject to available internet bandwidth, and Backblaze includes a throttle setting that allows users to limit the upload speed during working hours to reduce any impact on other network activity.

Initial Backup Duration For computers with a large existing volume of files, the initial full backup takes a significant amount of time to complete — potentially days or weeks for very large collections on connections with moderate upload speeds. This is standard behavior for any unlimited cloud backup service performing a first-run upload of an existing library. Backblaze continues to capture and queue new file changes during this period, prioritizing recently modified content.

External Drive Handling In tested scenarios, external drive backup was included automatically without additional setup. The 30-day retention policy for disconnected drives was reflected accurately in the interface, which flags drives that have not been connected recently. Users who connect external drives infrequently should be aware of this policy and connect their drives at least once within every 30-day period to maintain backup coverage for those files.

File Recovery Restoring files through the Backblaze web interface in tested scenarios was reliable and straightforward. Individual files and folders were locatable through a file browser, and zip file generation for larger selections completed without errors. The physical drive delivery option provides a meaningful alternative for users who need to restore large datasets and cannot afford the time required for a full internet-based download.

Pricing & Plans

Backblaze Personal Backup is available on a monthly or annual subscription basis, with a single flat-rate price that includes unlimited storage for one computer. There are no storage tiers, no per-gigabyte charges, and no additional fees based on how much data is backed up. The extended version history add-on, which extends file retention beyond the standard one year, is available at an additional cost.

A free trial is available, allowing users to evaluate the service and begin their initial backup before committing to a paid plan.

Current pricing, plan details, and trial availability are listed on the official Backblaze website. Users are advised to check the provider’s platform directly for the most accurate and up-to-date information before subscribing.

Use Cases

Everyday Computer Users: Individuals who want their entire computer backed up automatically without configuring which folders to include or monitoring storage usage will find Backblaze’s unlimited, whole-computer model directly suited to that need. Once installed, it requires no ongoing management to maintain comprehensive coverage.

High-Volume Creative Professionals: Photographers, videographers, and other creators who produce large files regularly benefit from the unlimited storage model, which ensures their archives are fully protected regardless of how much data accumulates over time.

Users with External Drive Collections: Those who store significant amounts of data on external USB drives alongside their main computer can include all of that content in the same backup without additional subscriptions or configuration steps.

Budget-Conscious Users Wanting Predictable Costs: The flat-rate pricing model makes Backblaze easy to budget for, as the monthly or annual cost does not change regardless of how much data is backed up. Users with large and growing archives avoid the cost uncertainty associated with per-gigabyte or tiered storage pricing.
