Time Travel vs Fail-safe recovery window

A permanent table was dropped 5 days ago in an account where the table's DATA_RETENTION_TIME_IN_DAYS was 3. The team now needs to recover the data. What is the current state?

  1. A.The data can be recovered by running UNDROP TABLE immediately.
  2. B.The data is in Fail-safe and is only recoverable through a Snowflake Support request.
  3. C.The data is permanently gone — both Time Travel and Fail-safe have expired.
  4. D.The data is available via SELECT ... AT (TIMESTAMP => ...) for up to 90 days back.
Show answer and explanation

Correct answer: B. The data is in Fail-safe and is only recoverable through a Snowflake Support request.

Why: The 3-day Time Travel window expired 2 days ago, so UNDROP no longer works. Permanent tables get 7 additional days of Fail-safe after Time Travel ends (day 3 → day 10), so the data still exists but is not user-accessible — Fail-safe recovery requires opening a support ticket with Snowflake. If this were day 11+, the data would be gone for good.
