It is important (understatement) that you take regularly scheduled backups of your PostgreSQL system as well as manage how many backups you have, which is known as "backup retention." These best practices ensure that you always have a recent backup of your database system to recover from in the event of a disaster (or use to clone a new copy of your database ) and that you don't run out of storage on your backup device or blow up your object storage bill (true story from a previous life, I ha...

One of the great things about PostgreSQL is its reliability: it is very stable and typically “just works.” However, there are certain things that can happen in the environment that PostgreSQL is deployed in that can affect its uptime, such as: • The database storage disk fails or some other hardware failure occurs • The network on which the database resides becomes unreachable • The host operating system becomes unstable and crashes • A key database file becomes corrupted • A data center is lost...

The Crunchy PostgreSQL Operator supports various forms of storage for provisioning PostgreSQL clusters in a Kubernetes environment. One such provider is Rook , which provides an abstract layer around multiple storage systems available in Kubernetes, which makes it even more convenient to choose between multiple storage engines. One storage engine that Rook supports is Ceph , which provides several types of distributed storage platforms including block-level storage, which is very helpful f...

Kubernetes is a very popular container orchestration framework. I’ll show you how to get Symmetric-DS working on a single Kubernetes instance. I had previously explored how to build an active-active PostgreSQL cluster using Symmetric-DS. The steps are essentially the same on Kubernetes: 1. Start 2 PostgreSQL pods 2. Create a user and a database on each pod/instance 3. Start the primary symmetric-ds pod 4. Add the symmetric-ds triggers and routes 5. Open registration 6. Start the secondary s...
