RDS for MySQL on AWS allows you to restore to any point in time for your backup retention period, minus the last 5 minutes or so. Restoration creates a new instance, it does not overwrite whatever instance you’re restoring. AWS’s use of the word restore is a bit confusing because restore often means “take your production database server and overwrite it with data from a backup”. As far as I can tell, Amazon never means this. When you restore, AWS creates another database server and writes all the data to the new instance, both when you’re using restoring to a point-in-time or from a DB snapshot. If you needed to switch servers, you’d have to point your database to the new instance.
