Restore App Release Notes (Mac)

Release Version 9.2.2.878

Improvements

• The Computer Backup Restore App now supports email-based MFA, ensuring users can authenticate successfully when Email MFA is required.
• An improvement was made to the Computer Backup Restore App’s chunk handling to reduce disk space usage during restores. Chunks are now downloaded and assembled in a more efficient order, with used chunks deleted immediately to prevent excessive temporary storage and avoid restore failures.

Bug Fixes

• A fix was implemented to allow the Computer Backup Restore App to handle large file restores with default settings. Temporary files are now stored in a hidden directory within the restore destination, and chunk-ordering improvements reduce disk usage during restore, preventing failures on systems with limited boot drive space.
• An issue was resolved in the Computer Backup Restore App where region-specific date formatting (e.g., 12-hour time with AM/PM in European locales) caused incorrectly formatted timestamps to be sent to the server. This led to a server-side error and prevented the directory tree from loading during restore. The app now properly formats dates to avoid this failure.
• The Computer Backup Restore App no longer displays the “Send SMS Fallback Code” link for 2FV/TOTP users who do not have SMS fallback enabled. This prevents confusion by ensuring the link appears only when the feature is actually available.
• The Computer Backup Restore App now correctly displays only the selected backup in the file tree. Previously, selecting both Mac and Windows backups could cause drives from both systems to appear simultaneously, creating confusion during restore navigation.

Release Version 9.2.1.860

Improvements

• Files larger than 1 TB can now be successfully backed up and restored using the Backup Client. This ensures reliable handling of large individual files in backup and recovery workflows.

Bug Fixes

• Resolved an issue that prevented users with Microsoft single sign-on (SSO) and multi-factor authentication (MFA) enabled from creating restores using the Computer Backup Restore App. Previously, attempts to authenticate would fail with a 404 error. The Computer Backup Restore App now correctly supports Microsoft SSO authentication flows.

Release Version 9.2.1.852

Bug Fixes

• An issue was resolved where the Computer Backup Restore App displayed the message "There were #### files that could not be written" without sufficient context.
• An issue was resolved that caused an “invalid login” error for users with weak account passwords.
• The Computer Backup Restore App now correctly isolates restore data per user session to prevent restores from appearing in the list when a different user signs in.

Release Version 9.2.0.836

Bug Fix

• A Computer Backup Restore App Installer issue was resolved to ensure a smooth setup and update process.

Release Version 9.1.0.832

Bug Fix

• An issue in the Computer Backup Restore App was resolved where the list of backups would fail to display if an error occurred with the first (pre-selected) backup.

Release Version 9.1.0.818

Improvements

• Updates were made to the Computer Backup Restore App distribution files, improving performance, compatibility, and reliability.
• A redundant View Summary link was removed from the restore progress dialog.

Bug Fix

Release Version 9.0.1.778

Improvements

• In the Backblaze Help menu, an option to submit user feedback or report an issue was added.
• The Restore App was improved to remove binary dependencies during the SSO call to the Backup Client app.
• The app now provides an available disk space value.
• The app now supports unicode strings, filesystem locations, and mount points. 
• Temporary file paths were shortened making it less likely for users to exceed character limits.
• When a change is made to the account email address, the password field clears automatically.

Bug Fixes

• Private encryption keys no longer appear in the local restore app user log.
• Sorting a file list by name now matches the directory in Mac Finder.
• The two-factor verification/time-based one-time password fallback code now sends a new code when requested.
• The View Skipped Files log is now in standard time instead of military time, and a “Detailed Info” link is displayed.
• The timestamp on the “Restore Progress” window is now in standard time instead of military time.
• After a restore is complete, the Pause button now changes to “Show in Finder.”
• An attempt to restore a backup with zero files in it now returns a “No Files Found” message.
• The default network settings were adjusted.
• The warning text that is displayed at the bottom of the Select Files window was updated.
• When the server crosses a specific threshold when a file is not sent, an error message is now displayed that indicates a problem.
• The progress message for a large restore now appears within the first minute to indicate that the app is not frozen.
• For a newly created backup, the “Failed to load directory tree” message now provides actions, such as selecting a different backup.
