Retention and deletion controls
Retention and deletion controls turn a retention policy into something that actually happens: schedules per data category, the technical means to delete or anonymize data when its period ends, the handling of legal holds, backups and vendor copies, and the evidence that deletion occurred. They are needed when the organization keeps everything because nobody owns deletion, when a regulation or contract limits how long data may be kept, when a deletion request cannot be honored across all systems, or when an incident exposed data that should have been gone years earlier. The controls produce a retention schedule tied to the data inventory, implementation of deletion in each system where feasible, procedures for holds and exceptions, and the records that demonstrate the schedule is applied.

Questions
Asked before engaging.
What about data in backups?
Backups are addressed by retention of the backups themselves and by procedures that prevent restored data from outliving its period. Deleting from every backup is rarely feasible and rarely required.
Can deletion be automated?
In many systems, yes. Where it cannot, a scheduled procedure with records is the alternative. The implementation plan says which applies where.
How does this interact with litigation holds?
The hold procedure suspends deletion for the data in scope and records it, so deletion can resume correctly when the hold lifts.
