Does anyone know what would cause a database to suddenly have deleted records return. I have to two databases one “backlog” and the other “donelog”. When an item in the backlog is completed I give it an invoice number and then it is moved to the donelog (deleted from the backlog). Twice in the last two years those records reappeared in the backlog. There are no scripts and too many for this to be human error. Could a power failure cause this to happen? Has something like this happened to anyone else?
