Backup Kubernetes Resources

Kubernetes is becoming a vital aspect of enterprise IT environments as businesses increasingly rely on containerized applications. And a large amount of data is generated by business applications and microservices everyday, which must be protected with a reliable backup and recovery solution.

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 Cluster Resources

Backup Cluster Resources

Backup the YAML representation of the resources of your entire cluster or a particular namespace. You can also use label selector to selectively backup particular resources.

Backup Application Resources

Backup the YAML definition of your application along with it's dependants. Stash recursively backup the dependant objects using the owner reference chain.

Backup Application Resources
Declarative API

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.

Deduplication
Data Encryption

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.

Monitoring
Policy Based Backup

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.
