Backup Client Release Notes (Mac)

Release Version 9.2.1.852

Improvements

• The Computer Backup Installer now includes several enhancements to two-factor authentication, such as improved error handling, localized error messages, and SMS fallback detection.
• Vulnerable third-party library dependencies were upgraded.
• The Computer Backup Installer now supports reinstalling the application on systems where a previous backup was removed via self-destruct.
• The Computer Backup Installer now explicitly closes Backblaze B2 sessions when completed to reduce unnecessary open sessions.
• The Full Disk Access tutorial in the Computer Backup Installer was updated to reflect the latest macOS requirements and provide clearer guidance.
• The Backup Client now detects bzdone lines containing multiple HGUIDs. It identifies affected FGUIDs, determines which files are still present on disk, and re-uploads them with a new, valid FGUID. For files that are no longer present, the Backup Client generates new x lines to mark them as expunged. This enhancement improves backup accuracy and ensures un-restorable files are correctly marked.

Bug Fixes

• An issue was resolved that caused the spacebar to become unresponsive in the password field.
• An issue was resolved where modifying settings in the Exclusions tab caused the Backup Client to freeze.
• A Safety Freeze alert was implemented for Backup Clients without a private encryption key (PEK) set, ensuring that users are notified of prolonged backup issues.
• A privilege escalation vulnerability was resolved. Safer file handling was also implemented to mitigate time of check to time of use (TOCTOU) conditions.
• Logging was optimized to prevent excessive log file growth during attempts to back up unreadable cloud-based files.
• The Backup Client was updated to avoid backing up Backblaze B2 mounts for improved efficiency.
• Excessive and incorrect logging was resolved, reducing log file bloat and improving performance.
• An issue was resolved in which users upgrading to version 9.2.0.836 via auto-update encountered unexpected warnings related to bzfileids.dat. Some users also received messages indicating their Backup Client had not backed up in several days, despite being active.
• An issue was resolved where the silent upgrade option did not produce any log file output.
• Password generation was improved in the command-line installer to align with updated security best practices.
• An issue was resolved that allowed the removal of default folder exclusions in the Backup Client. This behavior was corrected to prevent modification of default exclusions.

• An issue was resolved that caused an “invalid login” error for users with weak account passwords.
