IFO4
Loading...A storage snapshot whose underlying source has been deleted, whose retention period has elapsed, or whose intended purpose has been superseded, but which remains in the snapshot store accruing charges. Stale snapshots are the second most common source of orphan storage waste after detached volumes. The federation requires snapshot retention policies to be explicit, automated, and audited, with stale snapshot detection running on every weekly cycle. UFMS-001:2.4(c) governs the retention SLA and the documentation required for compliance-held snapshots.
A compound of stale, of food gone bad in fourteenth century English, and snapshot, the photographic term applied to disk imaging in the 1990s.
Federation members run stale snapshot detection weekly. Snapshots older than the documented retention SLA are auto-deleted unless tagged for compliance retention with a documented basis under MEV-Annex:3.2. Snapshot bills are reconciled to the snapshot register monthly.
