What is the best practice for keeping an Amazon RDS UAT database refreshed weekly from a Production version of that database? We were thinking of mirroring the production RDS, but we don't want any changes in UAT to be reflected in Production. So the thought of taking a weekly backup of production and restoring it to the UAT, but this is time consuming. Can we apply a snapshot of Production onto UAT if UAT is initially a restore of some point in time from Production?
回答1:
RDS offers two mechanisms for database backup/recovery. You can utilize the automated backups to allow point in time database recovery/creation. Alternately you can utilize database snapshots to make manual or automated snapshots that you can use to create new RDS instances.
