What type of data retention does Snowflake storage support?

1. Permanent storage only

2. Data retention for Time Travel and failsafe

3. Only real-time data retention

4. Temporary staging data retention

The correct answer is: Data retention for Time Travel and failsafe

Snowflake storage supports data retention mechanisms that include Time Travel and failsafe features, which are critical for ensuring data accessibility and recovery in various scenarios. Time Travel allows users to access historical data, enabling them to query and retrieve data as it existed at a specific point in the past. This capability is particularly useful for recovering from accidental data modifications or deletions, as it provides a way to view or revert changes without the need for separate backup solutions. Failsafe is an additional layer of protection that kicks in after the Time Travel retention period expires. It provides a means to recover data that may have been lost or deleted, ensuring that users can retrieve data even in catastrophic scenarios. This feature is particularly appealing for compliance and audit purposes, as it helps organizations maintain data integrity over time. The other options mention either permanent storage, real-time data, or temporary staging data retention, which do not accurately reflect the specific features offered by Snowflake regarding data management and retention strategies. Snowflake’s design emphasizes its capabilities in temporal data management and resilience, making Time Travel and failsafe the primary mechanisms it uses to manage data retention.
