Cloning operations can be used generate snapshots of tables at specified times. The snapshot objects can be stored in a first-tier storage with the table, where the cloned versions of the tables and the table may share files, such as micro-partition files, to conserve storage resources. After a first expiration time, snapshot objects can be transferred from the first-tier storage to a second-tier storage to further save on storage costs. After a second expiration time (e.g., full retention period), the snapshot objects can be deleted from the second-tier storage as well.
