auto-backup constantly deleted

My auto-backup deleted as soon as it is created. I tried to have the auto-backup folder open next to CorelDraw, and I can see the backup file appear at the frequence I set in the Options/Workspace/Save dialog, but it only stays for a fraction of a second and then disappears.

Can anyone help fix this behavior so I can recover after a crash (which happens every time I try to print on our HP Color LaserJet 4700, but that is another story...)?
