Backblaze has stopped backing up OneDrive and Dropbox folders

In Backblaze Personal backup, the .git, Dropbox, and OneDrive folders are no longer backed up, and there is no way for users to re-include them in settings.

The change was quietly noted only under the "Improvements" section of the release notes, with no email or notification. The official reasons given are performance issues, preventing unnecessary uploads, and avoiding excessive data usage, but it is being perceived as a feature reduction that actually narrows backup coverage.

At the core is damage to trust. Backblaze has long touted its promise to "back up all your data" and its unlimited personal backup as key strengths, but this change effectively excludes cloud sync folders and VCS directories.

The author emphasizes that sync and backup are different.

• OneDrive and Dropbox have short deletion retention periods.
• If an account is suspended, deleted, or a sync error occurs, they cannot serve as a long-term recovery method.
• So removing cloud folders from backup significantly lowers data safety.

Ultimately, the piece criticizes Backblaze for quietly changing the essence of what a backup service users had come to expect, not merely adjusting a policy. It raises the concern that a product once seen as "a service you can trust with all your files" no longer guarantees that premise.
