Retention Bloat

I. Formal Definition

The accumulated cost of data retained beyond any documented business or regulatory need, particularly in observability, log, and backup systems. Retention bloat is the structural counterpart to log retention waste: it captures the long-term accretion of data whose retention purpose has lapsed. The federation requires every data store with material retention to have a published retention policy linked to a regulatory, business, or analytical basis. Data without a linked basis is reclassified as bloat and pruned on a quarterly cycle under UFMS-001:2.4(e).

II. Etymology

A combination of retention and bloat, an Old English term for swelling; the cloud cost sense stabilised with the rise of long-tail observability bills.

III. Federation Usage

Federation members publish retention policies tied to documented bases. Untied retention is pruned quarterly and reported under MEV-Annex:3.2. Retention bloat is a recurring item in the FinOps inform report and a quarterly metric in the IFO4 Score calculation.
