Conclusion


You've learned how to take a snapshot of your data. Snapshots can be used effectively for different purposes in development, testing, and production. You can use historical data to summarize and analyze data from specific time frames. You've also seen how to audit changes to your data and how to restore individual records using audited data. By saving historical data and auditing changes to your database, you can ensure the integrity of your data by being able to back out individual changes without having to restore the entire database.
