A data retention policy should help the organisation keep information for a defined purpose and dispose of it when the purpose, requirement, or approved period ends. Keeping everything forever creates security, privacy, cost, and discovery risk; deleting data without understanding obligations can also create risk.
Short answer: build a data retention policy around data categories, purpose, owner, system, retention trigger, approved period, legal or contractual requirements, access, disposal method, exceptions, and review evidence. The policy should set direction while a retention schedule records the changing details.
This is general governance guidance, not legal advice. Retention requirements depend on the organisation, jurisdiction, data type, contract, litigation or investigation status, and business purpose.
Define the purpose of retention
For each data category, state why it is kept. Possible purposes include:
- Operating the service.
- Supporting customer or supplier obligations.
- Security monitoring and incident investigation.
- Financial, employment, or regulatory records.
- Backup and recovery.
- Legal claims, disputes, or an approved legal hold.
Do not retain data solely because storage is available. The purpose should justify the period and access model.
Create a retention schedule
The policy can define the principles while a schedule captures the details.
| Data category | System or owner | Retention trigger | Period decision | Disposal or review |
|---|---|---|---|---|
| Security logs | Security or platform owner | Event date or collection date | Risk, investigation, and requirement | Secure deletion or overwrite |
| Customer records | Service or data owner | Relationship or transaction end | Contract, service, and applicable requirements | Approved deletion or anonymisation |
| Incident evidence | Incident or security owner | Incident closure or legal hold release | Investigation, review, and obligation | Restricted archive and controlled disposal |
| Backups | Infrastructure owner | Backup creation and recovery cycle | Recovery objective and storage risk | Expiry and secure destruction |
Avoid one retention period for all data. Record the decision, owner, scope, source, and review date.
Define access and protection during retention
Retained data remains a security responsibility. Address:
- Who can access each category.
- How access is approved and reviewed.
- Encryption and key management where appropriate.
- Separation of production, archive, backup, and investigation access.
- Protection from alteration or unauthorised deletion.
- Handling of personal, customer, sensitive, or forensic material.
- Supplier and cloud-storage responsibilities.
Retention should not become a reason for broad access. Keep information only as accessible as the purpose requires.
Define secure disposal
State how information is deleted, overwritten, anonymised, destroyed, or removed from active and backup systems when the approved period ends.
Define what happens when immediate deletion is not technically possible. The organisation may need a controlled deletion queue, documented backup expiry, or restricted archive until the data can be removed. Record the limitation and owner rather than claiming deletion happened earlier.
Handle legal holds and investigations
The policy should provide a route to pause ordinary disposal when a legal hold, investigation, incident review, or other approved preservation need applies.
Record:
- Who can issue and release the hold.
- What data and systems are covered.
- The reason and start date.
- Access and preservation controls.
- Review and release conditions.
- How the normal retention schedule resumes.
Do not let an informal request suspend disposal indefinitely. Escalate unclear or conflicting obligations to the appropriate legal, privacy, security, or governance role.
Separate policy from the retention schedule
The policy should define purpose, ownership, principles, access, exceptions, and review. The schedule can hold data-specific periods, triggers, systems, and disposal details.
This separation makes it easier to update a period when a system or requirement changes without rewriting the entire policy. Link the schedule to data classification, supplier, backup, logging, and incident-response records.
Review retention after changes
Review the policy and schedule after:
- A new data type, product, region, or supplier.
- A new collection purpose or use of data.
- A security incident or investigation.
- A change in backup, logging, or storage architecture.
- A legal, contractual, or customer requirement.
- A failed disposal test or expired legal hold.
The policy review cadence guide explains how to combine regular review with material-change triggers.
Where Framework Pro fits
Framework Pro can help draft a tailored data-retention policy and supporting documents from business context and selected controls. The organisation remains responsible for the actual retention decisions, data inventory, legal and privacy review, implementation, evidence, and disposal operations.
Frequently asked questions
What should a data retention policy cover?
It should cover purpose, data categories, owners, systems, retention triggers and periods, access, protection, disposal, backups, legal holds, exceptions, evidence, and review.
Should all company data have the same retention period?
No. Retention should reflect purpose, risk, data type, operational need, legal or contractual requirements, and disposal capability.
Can a legal hold pause normal deletion?
It may, when issued and managed by the authorised role. Record the scope, reason, owner, access, review, and release conditions.
Does keeping data longer improve security?
Not automatically. Older data increases access, storage, privacy, and breach exposure unless there is a clear purpose and appropriate protection.
How does the policy relate to backups?
Backup retention should be defined consistently with recovery needs, security, disposal, legal holds, and the ability to restore or remove data as required.
