Restore Finishes but Deletes itself

Have you guys seen this issue before where the backup finishes successfully but the restored folder appears to have been deleted by Duplicati. Is there a way of getting it back or should I do the restore again? What causes it so I can avoid it when I do the restore again?
shows no code capable of that. Not total proof, but I don’t recall hearing of this. Feel free to search…

How was deletion traced? One Windows way is Sysinternals Process Monitor on a small file deletion.
On Linux, strace can do that, and Linux is also more likely to delete files that have been idle too long.

Are you restoring to original source file location, custom location, temporary file folder, network, what?
