Flushing logs is optional here but will add it to our post- backup rule for completeness.Ĭreate this rule in the PX-Backup interface. This may be required if users need a clear distinction between logs before and after a backup occurs. It also may be a good idea to FLUSH LOGS, which “ Closes and reopens any log file to which the server is writing ” and updates the sequence number of the log. MySQL documentation tells us that this is because global locks are not implicitly unlocked after the FLUSH TABLES WITH READ LOCK operation. Since we made sure to flush and lock data from MySQL before our backup, we must make sure to UNLOCK the database from the global read lock. The above command can be added to the “Action*” text box in the PX-Backup interface. ( Running Portworx ) KBVER=$(kubectl version -short | awk -Fv '/Server Version: / ' You can easily copy the command to add stork to your cluster. > Refer to the Add Cluster screen within the backup UI. If your backup icon is not green, double check that you are running Stork 2.4+ in the cluster you added. There should be a green backup icon in the cluster tile that will bring you to the backup view for the cluster. Once you have done this, you should see your cluster added to the main screen. Also, if you do not have access to the Portworx cluster details or are not using Portworx for volumes, you can leave that section blank. If you only have access to one namespace, you will only be able to set up backup and restore for that namespace. Keep in mind that the Kubeconfig is what controls the type of access you have to the cluster, and the same is true within PX-Backup. Then you will need to provide a cluster name and a Kubeconfig for the Kubernetes cluster you are using as well as the Portworx details if you have access to them. Within the PX-Backup interface, select Add Cluster from the navigation. > Note, this blog does not go into installing PX-Backup for this, please reference our documentation. Performing backup and restore for MySQLīefore we can backup MySQL, we must first configure PX-Backup with the access to the cluster which it is running in. We’ll walk through and explain these critical steps for backing up MySQL in production in more detail as well as provide examples and screenshots below. Make sure any application-aware hooks are in place so your backups are app-consistent.Plan out what type of schedule and retention plan your backups need.Make sure you know where your backup targets will be located.Know what level of RPO (recovery point objective) you require.Understand WHO will be responsible for creating backups.Given this, it’s best to understand the essential steps for creating a backup and restore plan in production. In production, we typically need the best level of protection that fits our business needs as well as those of our customers. When you are creating a backup and restore strategy, it is important to remember that not every data service needs the same level of protection. The essential steps to backup MySQL on Kubernetes
#MYSQL ENTERPRISE BACKUP RESTORE SINGLE DATABASE HOW TO#
This blog post will aim to answer most of the questions you may be asking and provide a clear guide on how to backup MySQL on Kubernetes in production. Can I restore to another Kubernetes cluster?.How long do my backups remain available?.How can I backup my PersistentVolumes (PVs)?.What Kubernetes objects do I need to backup?.Here are some of the things you need to ask yourself when protecting MySQL with backup and restore on Kubernetes in production: We have covered how to run a highly-available MySQL service on Kubernetes in production already, and now we are going to focus on the best way to protect your data services in production with backup and restore. Running applications-especially stateful applications in production-requires care and planning. Kubernetes runs mission critical applications in production that is a fact.
