Determining archive retention timelines
Retention length varies by industry, regulation, and business needs. There is no single correct duration, but most businesses use a mix of legal requirements, operational value, and cost to set retention schedules.
Typical retention ranges by use case:
- Financial and tax records: 6–10 years (varies by jurisdiction).
- Contracts and legal documents: 7–10 years or the term plus a statutory period.
- Employment records: several years after termination, often 3–7 years.
- Product and project archives: kept indefinitely or until obsolete.
- System logs: weeks to several years depending on compliance and forensic needs.
To create a practical retention policy, follow these steps:
- Inventory data types and map applicable legal/regulatory requirements.
- Classify records by business value and access frequency.
- Assign minimum retention periods and review cycles.
- Implement automated enforcement and secure disposal procedures.
Keep in mind that longer retention increases storage and governance overhead. Leverage tiered storage and policies like legal holds to balance cost and compliance. Regularly review retention rules as regulations and business needs change.
