The Snowflake features that provide continuous data protection automatically are Time Travel and Fail-safe. Time Travel allows you to access historical data at any point within a defined period, ensuring that you can recover from accidental data changes or deletions. Fail-safe provides a seven-day period during which Snowflake can recover historical data for operational or legal reasons after the Time Travel retention period has ended. Incremental backups is not a feature in Snowflake, and internal stages and zero-copy clones do not specifically provide continuous data protection as they serve different purposes.
