HC Deb 16 October 1996 vol 282 c1030W
Mr. Redmond

To ask the Secretary of State for Social Security on how many occasions in the last 10 years national insurance records have been mislaid; what back-up system was available in each case; and how secure is the current computer system. [40842]

Mr. Burt

There have been no instances of loss of registered national insurance records within the last 10 years. The back-up system consists of holding two copies of records within the computer installation and one copy remotely for added security. The computer system is regarded as very secure in protecting records and has a sophisticated series of computer program checks to detect corruption and loss of personal data.
