O&O AutoBackup 8 – What’s new?

8.2.1014 – released on October 21, 2026

Added:

• Per mirror and sync set: send replaced and deleted files to the Recycle Bin or delete them permanently
• Quiet list per set: known problem files are still retried but no longer reported
• Excluded folders can be entered as a path or as a pattern using * and ?
• Clicking notifications in the system tray opens the corresponding page
• “Backup drive is full” notification indicating the required space
• “Waiting for a quiet moment” status when a scheduled run is waiting for the computer to become idle

Changed:

• An unreachable source is treated as a warning instead of an error; the remaining sources are backed up
• Advanced settings of a set can now be changed later in the pair details
• Exiting during a backup stops the operation cleanly after confirmation
• Cleanup of old versions now displays progress and is logged
• WebDAV checks each destination folder only once instead of before every file
• Notifications for automatic and manual runs have been standardized
• Consistent colored icons throughout the application
• Rounded ends for progress bars without a known remaining amount

Fixed:

• Older program versions could reset the configuration
• Encryption could be switched while an operation was running
• Files created or modified during a run could remain permanently missing from the destination or the other side
• Individual files selected as sources were not backed up
• Default exclusions incorrectly restricted explicitly selected folders (e.g., Outlook .ost files)
• Shortcuts (.lnk) were missing from backups
• Files renamed and modified simultaneously arrived at the destination with outdated content
• Online destinations: modified files of the same size were not backed up
• S3: modified files larger than 5 GB were not backed up
• WebDAV: names containing spaces, umlauts, “#”, or “%” appeared empty
• WebDAV and S3: large uploads failed on slow connections
• Subfolders deleted from the source and files deleted during a run remained in the mirror
• Minimum and maximum file size limits were not applied
• “Continuously”: changes made during a run are now backed up immediately afterward
• Fallback copies created when the Recycle Bin is unavailable are now reported and cleaned up
• “Delete permanently”: files that cannot be deleted are now reported and retried
• After cancellation, files already transferred are no longer transferred again
• A missing destination or all missing sources are reported as a failure; the command line returns error codes
• An unreadable source is reported instead of being considered “everything in sync”
• If preparation of a run fails, the card displays “Failed”
• Locked files no longer trigger an error notification in the system tray
• WebDAV and S3: full quotas, unreadable folders, and unresponsive servers are now reported
• Encrypted copies now report the actual reason for a failure
• The same pair can no longer run twice, even after waking from sleep
• Scheduled backups involving multiple pairs resume after sleep
• The first backup started from the wizard now respects sleep, drive removal, and battery operation
• Cancel and Skip now also work for scheduled backups that have never completed
• Deleted or disabled pairs no longer execute from an active queue
• A missing source drive no longer interrupts a run when another device is connected
• Canceling the settings dialog no longer discards the result of an ongoing backup
• Errors saving the configuration after scheduled runs are now displayed
• The license is recognized when another user launches the application for the first time
• The configuration remains removed after uninstalling the application along with its settings
• Smart App Control no longer blocks synchronization
• Restarting after a language change failed when the installation path contained spaces
• The command line now rejects ambiguous pair names (exit code 4)
• Tiles once again exclude NTUSER.DAT and the Outlook OST cache
• Backups can now be created using only additional folders
• Excluded folders: editing, duplicate detection, and labeling corrected
• Progress page: information about the current file and transferred amount corrected
• A missing source file is now reported as “A file is missing”
• The restore log now correctly counts failed files
• Clicking older notifications in the Action Center now opens the correct pair
• Confirmation dialogs from the system tray now appear centered on the screen

Info:

• Compatible with Windows 11 and Windows 10; x86, x64, and ARM architectures
• Available in German, English, French, Italian, Spanish, Russian, and Simplified Chinese

8.1.1011 – released on September 7, 2026

Added:

• Destination folder templates for backup, synchronization, and restore, including placeholders, nested folders, preview, and an option to disable them
• Destination path can be changed in the wizard for an individual run
• Warning when backing up or synchronizing directly to the root directory of a drive or network share
• NAS and network shares as a dedicated destination type with stored credentials and automatic reconnection
• “Open folder” for source and destination in pair details; multiple sources offer a selection
• Option to request confirmation before deleting destination files during a manually started mirror or two-way synchronization
• “Continue in background” on every progress page: the operation continues while the display returns to the home page

Changed:

• Clicking the card of a running operation opens its progress page
• Edit, Restore, and Cancel are no longer available on the card of a running operation; cancellation takes place on the progress page
• Card statistics are refreshed when an operation finishes, even if the home page remained visible during the run
• Deletion confirmation counts only items actually removed, not replaced files
• The “Add destination” tile remains visible in long destination lists; newly added destinations are automatically brought into view

Fixed:

• Synchronization uses the selected destination folder and no longer creates a hidden “Sync” subfolder
• Expired trial versions remain available without an internet connection and start in the intended overdue state
• Missing folders on network shares are created and available space is detected correctly
• Backup pairs with multiple sources receive unique names based on the number of source folders
• A damaged working directory under %TEMP% is automatically repaired at startup
• Update checks and dialogs start only once; the dialog appears centered when the main window is hidden
• Previously detected updates remain available after skipped or failed checks
• The first backup starts only after the setup question has been answered, rather than running in the background while the dialog is open
• Runs deferred to the next full hour are scheduled at least five minutes ahead; otherwise, the following hour is used

Info:

• Compatible with Windows 11 and Windows 10; x86, x64, and ARM architectures
• Available in German, English, French, Italian, Spanish, Russian, and Simplified Chinese
