You can name this rule with intuitive name like `Database retention rule`Ĭreate a new IAM user.

This will keep you backup for extra 1 day after it marked as expired.

Standard has 99.99% availability, but Standard – IA has only 99.9% with lower cost. I suggest using either Standard or Standard – IA. AWS S3 has 4 storage classes: Standard, Standard – Infrequent Access (IA), Reduced Redundancy Storage (RRS), and Glacier. Just in case a failure in primary database region, you still have cold backups in another region.

UPDATE (2): As per bluetreble’s comment below, the backup retention will be done by AWS S3 Lifecycle management and remove IAM user privilege to delete objects in S3 bucket. The compression is slightly bigger than gzip, but the compressing takes lower CPU usage. wal-e can perform continuous archiving PostgreSQL WAL files and base backups. You can backup it weekly, daily or hourly, it depends on your RPO/Recovery Point Objective. So in this incident, you can restore your data. To mitigate this issue, we can set up a backup (i.e snapshot) of your database. The drop query is going to be replicated across all hot standby databases. Why should I have a cold database backup? Imagine someone accidentally delete your table (let’s say DROP TABLE users ). In case your primary (master) server failed, you still have another server that is ready to be a new master. You can make your slave servers as read-replica to reduce master server load. It is good to have hot standby database server.
