What is a data retention policy and how do you create one?

Building an effective data retention policy

A data retention policy defines how long different categories of data are kept, how they are archived, who can access them, and how they are safely disposed of. It ensures consistent handling of records and helps meet legal, regulatory, and business needs.

Key steps to create a policy:

• Inventory: List the types of data your organization holds and where it lives.
• Classify: Group data by sensitivity, legal requirements, business value, and access patterns.
• Define retention: Assign retention periods to each class, citing legal or business rationale.
• Specify controls: Outline storage locations, encryption, access restrictions, and archival format.
• Describe disposal: Set secure deletion and destruction procedures after retention expires.
• Assign roles: Designate owners responsible for enforcing the policy and handling exceptions.

A practical policy also includes processes for legal holds, audits, and periodic reviews. Automate enforcement through archiving tools and lifecycle management to reduce manual errors. Finally, communicate the policy across the organization and provide training so teams understand the retention obligations and how to tag or classify records correctly.
