Backblaze
Backblaze provides unlimited cloud backup for personal computers and scalable, low-cost object storage (B2 Cloud Storage) for developers and businesses. It is recognized for its straightforward approach, reliability, and competitive pricing.
Our take: Backblaze runs two complementary services: Personal Backup (unlimited Mac/Windows backup at a flat rate) and B2 Cloud Storage (pay-as-you-go object storage at roughly one-quarter of AWS S3 pricing).
The go-to for affordable unlimited PC backup and cost-conscious developers who need S3-compatible storage without the AWS price tag.

Our takeBackblaze runs two complementary services: Personal Backup (unlimited Mac/Windows backup at a flat rate) and B2 Cloud Storage (pay-as-you-go object storage at roughly one-quarter of AWS S3 pricing).
Why we rate itBackblaze is one of the few services that genuinely delivers on 'unlimited' backup without throttling, and B2's CDN egress partnerships make it a compelling alternative to AWS S3 for media-heavy workloads.
The catchPersonal Backup covers only one computer per subscription (external drives attached to that machine are included) and has no file-sync or sharing features.
Best / not good for
- Individuals needing unlimited, low-maintenance PC backup
- Developers and media teams seeking cheap, S3-compatible object storage
- Small businesses archiving large volumes of files without AWS-level budgets
- Teams needing file sync, sharing, or collaborative cloud drives
- Enterprises requiring SLA-backed support and compliance certifications out of the box
- Workloads that demand multi-region replication with a single-vendor native solution
Friction report
Trade-offs to know before signing up.
- Time to valueFast: Personal Backup installs in minutes and begins backing up automatically; B2 bucket creation takes under 5 minutes via web UI or API.
- Scale breakpointB2 egress costs climb if you exceed 3x monthly storage outside CDN-partner networks; Personal Backup is per-computer so multi-machine households pay per seat.
- Walled gardenLow: B2 is S3-compatible so data is portable via standard tools (rclone, AWS CLI); Personal Backup exports are available as zip downloads or physical drive restores.
