The Write Once, Read Many (WORM) snapshots feature is now in Preview.
WORM snapshots represent backups of specific Snowflake tables, schemas, or databases. These backups are immutable: they can’t be changed after being created. Snowflake manages all the snapshots of a specific object within a single container object, the snapshot set. You can establish snapshot policies that determine how often to automatically take new snapshots, when to automatically delete old snapshots, and when to prevent important snapshots from being deleted, even by privileged users.
For more information, see: Snapshots for backups and immutable storage.
