Snowflake’s continuous data protection feature set:

Time Travel

  • Available for permanent and transient tables
  • Can be accessed and queried manually by the users
  • Available for a maximum of 90 days* under an Enterprise license
    • Only up to 1 day for transient tables

Fail-Safe

  • Managed by Snowflake
  • Only available for permanent tables
  • Intended as a last resort
  • Recovered through support ticket
  • Non-configurable 7-day period

Note: While both provide powerful data protection, they can significantly increase storage costs depending on data change patterns. Frequent updates or deletes can multiply storage usage and it's recommended to monitor storage consumption regularly, especially for large and frequently changing tables.
