Backblaze silently redefines 'unlimited' backups and users discover it's not backing up Dropbox and OneDrive — as firm leans heavier into AI storage services, changes could signal shift away from home backups

Backblaze quietly changed its unlimited-backup policy and terms, making heavy users subject to throttling or account termination.

It also began excluding files synced from services like Dropbox, OneDrive, Google Drive, and Box from backups.

The changes were easy to miss, leaving some users to discover missing backups only when they needed to recover data.

That has raised concerns that Backblaze’s promise of unlimited, reliable backup is being weakened.
