Answer: 0 days

According to Snowflake documentation, transient and temporary tables do not have a Fail-safe period. Fail-safe is a feature that provides additional data protection for permanent tables after the Time Travel retention period ends, but transient tables only have Time Travel (0-1 day) and temporary tables have no data protection features. The community discussion with 100% consensus and upvotes confirms that the correct answer is 0 days, as referenced in the official Snowflake documentation link provided.
