Introduction Just like any other setup, the data in a Kubernetes cluster can be at risk of getting lost. To prevent serious issues, it’s essential to have a data recovery plan at hand. A simple and effective way to do this is by making backups, ensuring that your data is safe in case of any unexpected events. Backups can be run one-off or scheduled. It’s a good idea to have scheduled backups to ensure you have a recent backup to…

Introduction MySQL replication reliably mirrors the data and operations from one database to another. Conventional replication involves a primary server configured to accept database write operations with secondary servers that copy and apply actions from the primary server’s log to their own data sets. These secondary servers can be used for reads, but are usually unable to execute data writes. Group replication is a way of implementing a more flexible, fault-tolerant replication mechanism. This process involves establishing a pool of…

Introduction Backups are very important for cloud servers. Whether you are running a single project with all of its data stored on a single server, or deploying directly from Git to VMs that are spun up and torn down while retaining a minimum set of logs, you should always plan for a failure scenario. This can mean many different things depending on what applications you are using, how important it is to have immediate failover, and what kind of problems…

Introduction Importing and exporting databases is a common task in software development. You can use data dumps to back up and restore your information. You can also use them to migrate data to a new server or development environment. In this tutorial, you will work with database dumps in MySQL or MariaDB (the commands are interchangeable). Specifically, you will export a database and then import that database from the dump file. 1-Click deploy a database using DigitalOcean Managed Databases. Let…
