Sample Go application with database backend

Yes, this is one more sample app as there are probably thousands already on the internet. We have tons of sample apps from different vendors with various types of licenses available on different repositories. Nevertheless sometimes I struggle to find exactly what I need – a simple app with a database backend which can work with Oracle Autonomous databases and optionally with Postgres backend. In my everyday life I primarily use Go as a programming language and I would like to have such an app written using that language. So, eventually I gave up and created my own application with a simple frontend and two (as for now) options for backend databases – Oracle and Postgres.

AlloyDB backups management

The post is about backup management for AlloyDB. It might be useful for the time when it is written but, probably, will be obsolete very soon when tools and API for the service will mature.
A couple of words about AlloyDB backups and how they are created. The backups are quite different from the default backups for Cloud SQL for example. As we know in Cloud SQL all the backups are bound to the instance. What it means is when the instance is deleted then all the backups disappear along with the instance. It makes sense if the backups behind the scenes are storage snapshots from the databases. But in AlloyDB all the backups are decoupled from the cluster and exist by themselves. If you delete a cluster the backups stay. I think it is a way better approach because it provides a better way to protect from some mistakes when an instance is deleted before making a clone or exporting the data. As for now you can see all the backups for existing and deleted instances using the “backups” tab in the console, gcloud utility or listing using GCP REST API.

Google Cloud SQL Custom Backups

In one of my previous posts I’ve noted that the GCP Cloud SQL for SQL Server doesn’t have point of time recovery as of March 2022. As result the default out of box backups can only provide RPO as 24 hours or more. The exact RPO might vary from day to day since you can only specify a window for backup but not exact time. So far it seems like the only reasonable approach to reduce the RPO is to schedule on-demand backups, and in this post I am going to show how you can do that using a couple of different approaches.
