What is Percona XtraDB Backup?
But the problem is traditional backup and restore solutions were not designed for Kubernetes. If you want to copy a Kubernetes cluster over platforms, you have to face so many difficulties during the process. And when the application grows in size, you need to create a lot of new custom scripts to take snapshots of your pods, services, volumes, configmaps, secrets, and have to continuously maintain those scripts. Stash is a complete Kubernetes native disaster recovery solution for backup and restore Kubernetes workloads, volumes and databases on various public and private clouds.
As we already know, traditional tools are too complex to setup and maintain in a dynamic compute environment like Kubernetes. Stash is a Kubernetes operator that uses restic or Kubernetes CSI Driver VolumeSnapshotter functionality to address these issues. Using Stash, you can backup Kubernetes volumes mounted in workloads, stand-alone volumes and databases. Users may even extend Stash via addons for any custom workload.

Backup Percona XtraDB in 4 steps
Install Stash
Deploy Stash operator via Helm into your Kubernetes cluster.
helm install stashDefine Backup Policy
Create a BackupConfiguration CRD pointing at your Percona XtraDB instance.
kind: BackupConfigurationAutomated Backups
Stash schedules encrypted, deduplicated snapshots to your storage backend.
✓ Backup verifiedOne-Click Restore
Restore to any point in time with a single RestoreSession manifest.
kind: RestoreSessionBuilt for production reliability
Logical Backup
A logical backup contains copies of database information (such as tables, schemas, and procedures) and is often exported as a binary file utilizing EXPORT/IMPORT tools. Logical backups are useful if you need to restore or relocate a copy of the database to another environment. Stash offers Logical Backup for Percona XtraDB databases on Kubernetes.
Backup & Restore Percona XtraDB Databases
Backup your Percona XtraDB databases deployed in Kubernetes. You can also restore your Percona XtraDB databases using Stash. Stash simplifies the whole process of Backup & Restore your Percona XtraDB databases on Kubernetes.
Declarative API
Backup your data in Kubernetes native way. Stash uses Custom Resource Definition (CRD) to specify targets and behaviors of the backup and restore process. Schedule a backup for your workloads in the same way you deployed them into Kubernetes.
Deduplication
Stash will upload only the diff since the last backup. It splits the targeted files into smaller blobs using Content Defined Chunking (CDC) and uploads only the modified blobs.
Data Encryption
To provide data security, your data needs to be encrypted during the whole process. Stash keeps all the backed up data encrypted using AES-256. So, your data is protected even if it leaks from the backend. And it will not make any sense until they are decrypted.
Monitoring
Stash comes with native support for monitoring via Prometheus. You can use builtin Prometheus scrapper or CoreOS Prometheus Operator to monitor your database in Kubernetes. You can use the Grafana to view key operational metrics, including compute/memory/storage capacity utilization, I/O activity, and instance connections.
Policy Based Backup
Define a common template to backup all similar types of workloads. Then, just add some annotations to your targeted workload to enable backup for it. You can use a single template to backup all the Deployments, StatefulSets, DaemonSets, ReplicationControllers and ReplicaSets of your entire cluster
Multiple Storage Support
You can store your backed up data into various storage services. Stash supports AWS S3, Minio, Rook, Google Cloud Storage, Azure Blob Storage, OpenStack Swift, DigitalOcean Spaces, Blackbaze B2 and REST server as backend. You can also use Kubernetes persistent volumes as backend.
