0.1.4-beta

Prerelease for Windows 10/11 x64.

• own-backup-install.exe — setup wizard in English and Russian: installs the program for all users and starts its backup service; needs administrator rights. It installs over an earlier version, keeping settings and jobs.

Changed

• New VHDX and qcow2 disk chains reserve metadata space for all addressable source blocks, so filling a disk does not prematurely start another full backup. OBK increments reserve their own metadata space as needed.

Fixed

• A disk backup job follows partitions that Windows Update shrank, moved or recreated, such as the recovery partition. Before each run the job is matched against the disk as it is now and updated; the next copy is a full one, and the result says why. Such jobs used to fail with "file not found". A data partition that disappeared is never replaced by a guess.
• An incremental disk copy is never written over a parent copy with a different partition layout, which would have restored data into the wrong places.
• A copy that had to become a full one is named and recorded as a full copy, not with the name of the planned increment.
• Stopping an iSCSI target on Windows checks cancellation during socket waits, so an idle session no longer keeps the image open until its read timeout.
• Encrypted jobs can regain automatic access after their locally stored authorization is damaged, using the recovery key.
• Completed OBK images are published only after their data is durable; a restart removes unfinished images without exposing them as restore points.
• A backup that could not remove every excluded file reports the incomplete result instead of silently claiming full exclusion.
• Scheduled verification and the recovery of interrupted backup operations have been tightened.

Settings and jobs are kept in C:\ProgramData\OwnBackup, the service log in the Logs folder next to the program. The window needs the Microsoft Edge WebView2 Runtime: Windows 11 has it, and the installer says so if a Windows 10 does not.
