The term "retention policies" refers to defined rules and procedures that determine how digital information and documents are stored, protected, and - once retention periods expire - either deleted or archived in a tamper-proof manner. The objective is to comply with legal and internal requirements, reduce risk, control storage and system costs, and ensure traceability and compliance (e.g., for audits). Retention policies are commonly implemented in document management, archiving, email, and enterprise content management systems.
Rule-based retention periods: Defining retention times by document type, content, business process, or classification (e.g., invoice, contract, HR record).
Automatic classification & metadata-driven control: Assigning retention rules based on metadata, tags, document properties, or templates.
Event-based retention start: Starting retention based on defined events (e.g., contract termination, project completion, employee exit) rather than creation date alone.
Tamper-proof archiving (WORM/immutable storage): Preventing subsequent manipulation through immutable storage and logging.
Legal hold: Temporarily suspending deletion or destruction processes due to litigation, audits, or investigations.
Automated deletion & disposition workflows: Policy-compliant deletion or controlled disposal after expiry, including approval or sign-off processes.
Versioning & retention of changes: Managing document versions and defining which versions must be retained for how long.
Audit trail & evidence logging: Logging access, changes, retention actions, holds, and deletions to support auditability.
Role and permission management: Controlling who can define or change policies and approve deletions.
Reporting, monitoring & compliance dashboards: Insights into retention periods, deletion runs, exceptions (e.g., legal holds), and policy violations.
Invoices and accounting records are archived for a defined period and then automatically queued for deletion.
Contracts are retained for a defined period starting from contract end; the retention clock begins with the “contract terminated” event.
Business-relevant emails are retained for different lengths of time depending on category or sender group.
HR documents are retained for a specified period after an employee leaves and then securely disposed of.
When an audit is announced, a legal hold is applied so that relevant documents are not deleted regardless of retention periods.
