Backblaze has stopped backing up OneDrive and Dropbox folders and maybe others

📝 Discussion Summary (Click to expand)

1. Silent exclusions break trust in “unlimited” backups

Backblaze quietly drops whole directory classes (e.g., .git, cloud‑synced folders) without clear notice, turning the promised “back‑up everything” into a source of surprise data loss.

“I feel that’s a systemic problem with all consumer online‑backup software: they often use the barest excuse to not back things up… at worst it’s to quietly renege on the ‘unlimited’ capacity they promised.” — Terr_ ## 2. Users demand full control and transparency
Many commenters switched to tools that let them see and configure every detail—no hidden daemons, no opaque lock‑in, and no surprise exclusions.

“With restic I don’t need some kind of special server daemon… I like having the sense of options and avoiding lock‑in.” — Terr_

3. “Unlimited” is a marketing loophole, not a guarantee

The community repeatedly points out that any service advertising “unlimited” storage is inherently vulnerable to hidden caps, exclusions, or price hikes once the model becomes unprofitable.

“ANY company, and I do mean any, that offers ‘unlimited’ anything is 100 % a scam.” — massysett

4. Proper backups require clear definitions and regular restore testing

HN members stress that a true backup is simply a separate copy of data; versions, retention policies, and occasional restore drills are essential to avoid hidden corruption or loss.

“definition of the term backup by most sources is one the line of: a copy of information held on a computer that is stored separately from the computer.” — dathinab


These four themes capture the dominant concerns: loss of confidence in Backblaze’s opaque exclusions, the drive for transparent, user‑controlled backup tools, skepticism toward “unlimited” promises, and the necessity of concrete backup semantics and testing.

Backup Rule Transparency Dashboard

Summary

  • Provides a visual audit of all file exclusion and inclusion rules for popular cloud backup services (Backblaze, OneDrive, Dropbox).
  • Detects hidden or undocumented exclusions (e.g., .git, cloud sync folders) and flags recent changes.

Details

Key Value
Target Audience Power users, sysadmins, and developers who rely on automated backups.
Core Feature Real‑time rule inspector that lists every excluded path, its source, and recent modifications.
Tech Stack Electron front‑end, Node.js backend, APIs from Backblaze, OneDrive, Dropbox; stored locally SQLite.
Difficulty Medium
Monetization Revenue-ready: $6/mo per user (team plans available).

Notes

  • HN commenters repeatedly stress the need to “see what’s actually backed up” – this tool directly addresses that.
  • Could integrate with existing backup clients to auto‑adjust exclusions based on user preference.
  • Potential partnership with backup service providers for a white‑label version.

Automated Backup Rule Enforcement CLI

Summary

  • CLI tool that scans a user's backup configuration and automatically generates safe exclusion/include lists.
  • Enforces best‑practice rules (e.g., never silently drop .git folders) and offers one‑click remediation.

Details

Key Value
Target Audience Linux/macOS power users, DevOps engineers.
Core Feature Parses backup client config files, validates against a rule set, suggests or applies fixes.
Tech Stack Go (CLI), YAML/JSON config parsing, integrates with Restic, Borg, and native backup tools.
Difficulty Low
Monetization Hobby

Notes

  • Users complained about “silent changes” breaking restores; this tool makes those changes explicit.
  • Could be packaged as a GitHub Action for CI pipelines to verify backup configs on push.

Cross‑Cloud Backup Integrity Monitor

Summary

  • SaaS that periodically restores random snapshots from multiple cloud backends and records success/failure metrics.
  • Sends alerts when any backend (Backblaze B2, Wasabi, S3) exhibits missing or corrupted restores.

Details

Key Value
Target Audience Small‑to‑medium businesses, data‑critical professionals.
Core Feature Scheduled restore drills, checksum verification, unified dashboard.
Tech Stack Python backend, Celery workers, React front‑end, stores reports in PostgreSQL.
Difficulty High
Monetization Revenue-ready: $12/mo per monitored TB.

Notes

  • Discussion highlighted restored file corruption and missing history; this service directly mitigates those risks.
  • Aligns with the “test restores regularly” advice from seasoned users on HN.

Transparent Cloud Exclusion Negotiator (Web App)

Summary

  • Web platform where users can upload their backup client config files and receive a plain‑language summary of what will be backed up.
  • Offers a marketplace of community‑contributed exclusion rules and a forum for sharing fixes.

Details

Key Value
Target Audience Non‑technical users who rely on GUI backup apps but want clarity.
Core Feature Config parser that outputs a readable report, highlights risky exclusions (e.g., .git), suggests alternatives.
Tech Stack Full‑stack TypeScript (Next.js), serverless functions, Markdown documentation generator.
Difficulty Medium
Monetization Revenue-ready: $4/mo per active user (free tier for ≤5GB).

Notes

  • HN participants repeatedly asked for better communication and transparency from providers; this tool delivers that.
  • Could integrate with existing backup services via API to auto‑apply recommended exclusions.
