Clones in Snowflake have the advantage of being created almost instantly and saving space by not duplicating storage. This is due to Snowflake's zero-copy cloning feature, which allows for the creation of object clones without the additional storage costs typically associated with data duplication23. Clones are independent of the original table and do not stay in sync with it, nor do they inherently have better query performance. However, they do inherit the time travel history from the original table at the time of cloning

Explanation
Time travel and fail safe are the two continuous data protection features support the recovery of data automatically.
Snowflake provides powerful CDP features for ensuring the maintenance and availability of your historical data (i.e. data that has been changed or deleted):
* Querying, cloning, and restoring historical data in tables, schemas, and databases for up to 90 days through Snowflake Time Travel.
* Disaster recovery of historical data (by Snowflake) through Snowflake Fail-safe.
