No need to access potentially large SQL archive files that may be located on a remote backup server, find a suitable server to restore them to and wait for the process to finish – for a large database this can be a number of hours. However, with the out-of-the-box PITR solution that comes with AWS RDS, we are able to easily fire up a separate copy of the database at any recent point in time. And it is not as easy to keep always-up-to-the-minute copies of production data.

We have often opted for a simpler model that utilises full-database backup on an automated regular schedule – stored as an SQL archive on an external file system, which is then pushed to tape backup.ĭue to the way that full SQL dump's work, we incur higher storage costs holding numerous copies of the full database at particular points in time.
This can add a complexity overhead to the system management. An example request from the application team to a DBA might be: “Please restore a copy of database CRM_SYSTEM to its state on Tue, Jan 5th at 03:03am so that we can investigate a data issue.” So, What's the Difference?Ĭatalyst has set up PostgreSQL with full PITR support on a range of platforms in traditional bare-metal hosting environments. In AWS-speak, this functionality is called “ Automated Backups” and needs to be enabled on a per-database level – either via the AWS console or using API calls.Īs any Oracle DBA will tell you, true PITR is the ability to restore a database to an exact point in time within the defined retention window. We recently started taking more advantage of the Point-In-Time-Recovery (PITR) capabilities available for our RDS databases to satisfy our database backup and data retention requirements. Initially using the MySQL engine, and more recently moving to the PostgreSQL offering.Īpplying RDS in our cloud architecture stacks has allowed us to focus our engineering skills on application improvements and optimisation, without having to be distracted with the 24x7 overhead of managing a highly-available PostgreSQL instance with automated failover. Since 2012, Catalyst have been working with the Amazon Web Services (AWS) database-as-a-service offering – Relational Database Service (RDS). We are proud of the experience and capability we have developed in database provisioning, configuration, optimisation and ongoing ownership strategy (meaning full management responsibilities).īeing able to efficiently manage and support a mission-critical application database 24x7 is a core component in Enterprise service delivery.
Catalyst has been working with the great open source Relational Database Management Solutions (RDMS) MySQL and PostgreSQL for well over a decade.
