Read-Only Archive

An archive of a retired application's data that users can search and report on but cannot change, preserving it as an immutable record.

What Is a Read-Only Archive?

A read-only archive holds the data of a retired application in a form users can search, view, and report on but cannot create, edit, or delete. It replaces the application’s role as a place to look things up, without the application, its infrastructure, or its license.

Read-only is the point. Once a system is retired, its records are historical evidence. Allowing edits would undermine their value as a record of what happened. Access controls, audit logging, and tamper-resistant storage make the archive defensible when an auditor, regulator, or court asks whether the data has been altered.

Read-only does not mean permanent. Retention schedules still apply, and when a retention period ends, disposal should be a controlled, logged event driven by policy, not a user action. Some regulations go further and specify how electronic records must be preserved. SEC Rule 17a-4 for broker-dealers is a well-known example.

Key Points

Accessible, not frozen out. Users search and report against the archive, so the business does not lose visibility when the application goes dark.
Structure is preserved. Relationships between records and the way a business object such as an invoice hangs together, should survive, so records stay readable.
Controls make it defensible. Role-based access, audit trails, and tamper-resistant storage show that the record is what it claims to be.
Disposal follows policy. Deletion at the end of retention is a governed process with evidence, not an administrator’s judgment call.
It replaces the application’s user interface, not its business logic. The archive answers “what did we record?” It does not process new transactions.

Common Use Cases

Audit and regulatory lookups

An examiner asks for a specific transaction and its supporting detail from a retired system. The archive returns it with the surrounding records in seconds instead of weeks.

HR and payroll inquiries

A former employee requests earnings history from a system retired years ago. Staff retrieve it from the archive without restoring the old payroll application.

Legal discovery

Counsel needs records from an application that no longer exists. The archive supports search, export, and legal hold without touching production systems.
