 ### Check strategy
 The `check` strategy is useful for tables which do not have a reliable `updated_at` column. This strategy works by comparing a list of columns between their current and historical values. If any of these columns have changed, then dbt will invalidate the old record and record the new one. If the column values are identical, then dbt will not take any action.

 #### Ensure your unique key is really unique
 The unique key is used by dbt to match rows up, so it's extremely important to make sure this key is actually unique! If you're snapshotting a source, I'd recommend adding a uniqueness test to your source ([example](https://github.com/dbt-labs/jaffle_shop/blob/8e7c853c858018180bef1756ec93e193d9958c5b/models/staging/schema.yml#L26)).

 #### Use a `target_schema` that is separate to your analytics schema
 Snapshots cannot be rebuilt. As such, it's a good idea to put snapshots in a separate schema so end users know they are special. From there, you may want to set different privileges on your snapshots compared to your models, and even run them as a different user (or role, depending on your warehouse) to make it very difficult to drop a snapshot unless you really want to.

 In comparison, models build into a separate schema for each user — this helps maintain separate development and production environments.
