Alex is basically correct.
The backup location that the original frames are saved to is in a hidden folder called .resolve_backups and this folder will be placed in the root path of the volume that the DPX source files reside on.
It seems unlikely that Undo would fail, because it won't do the fix unless it can make a backup of the original frame first.
You do need to be on the exact frame the fix was done on, for Undo to work.
