Does a data processor need to be informed when a data controller deletes data?
A Data Processor only needs to be informed if the Data Controller is in need of support, in regard to undertaking the right to be forgotten. Although, it is important for a data controller to define the relationship with the data processor, in order to understand the dynamics between the two. It is also seen as good practice to allow the controller to gain access to deleted records through a Subject Access Request that the controller has obtained. If a Data Processor retains copy records as well as back up records, they must be deleted if requested by the Controller.
The deletion process can be difficult to carry out efficiently, although it is an essential process, according to GDPR, all the subject’s data must be deleted and backed up again, which is a lengthy but essential process.
