A data archive is a stored collection of older records kept for retention, audit, or recovery rather than for everyday working use.
The live system stays small and fast, while the archive holds claims, invoices, or messages that the law or the business still needs.
How it works
An insurer moves closed claim files to an archive after the case ends, and investigators can still retrieve a file years later.
Staff do not edit those files in the daily claims tool, which reduces the chance of an accidental change.
If the archive is poorly protected, old identity numbers and medical notes remain a target long after the customer forgot the policy.
If it cannot be read, the insurer may fail an audit or be unable to answer a dispute about a past payout.
Concrete examples
- A bank keeps seven years of account statements in an archive that tellers cannot change.
- A hospital stores discharged patient scans on archive media that a researcher can request through a recorded approval.
- A shop retains old order invoices in an archive so a chargeback from last year can still be documented.
Protective measures
- Limit who can read the archive and record each retrieval of a closed claim.
- Test once a year that a sample of archived files still opens, including the index you would use in an audit.
- Keep the archive on separate credentials from the daily claims desk so a stolen teller password does not open every old file.
- Apply the same retention end date you promised customers, and delete or further restrict files when that date passes.
