Stash

Backup your Kubernetes Stateful Applications

Stash

Product Features

http

Declarative API

Backup your data in Kubernetes native way. Stash uses Custom Resorece Definition (CRD) to specify targets and behaviors of backup and restore process. Schedule a backup for your workloads in the same way you deployed them into Kubernetes.

http

Restic

Built-in on top of open source backup program Restic (restic.net) . It provides fast, secure, efficient and verifiable backup facility.

http

Backup Kubernetes Volumes

Backup your Kubernetes volumes mounted in a workload. Stash supports Deployment, DaemonSet, StatefulSet, ReplicaSet, ReplicationController, OpenShift DeploymentConfig etc. You can also backup stand-alone PVC with "ReadWriteMany" access mode.

http

Backup Database

Backup your databases deployed in Kubernetes. Stash supports backup of PostgreSQL, MySQL, MongoDB, Elasticsearch and Percona XtraDB databases. It seemingly integrates with KubeDB. It is now recommended method to backup KubeDB supported databases.

http

Volume Snapshot

Take scheduled snapshot of the volumes of your workload using Kubernetes VolumeSnapshot API. Stash removes the burden of creating VolumeSnapshot manually for each volume used in your workload. Instead, just create a single BackupConfiguration for the workload and Stash will do the rest for you.

http

Cluster Snapshot

Backup your cluster resources definition periodically so that you can recover your cluster in case of any disaster.

http

Batch Backup

Often an application consists of more than one component. For example, an application may have a front-end and a back-end. Stash supports taking backup of multiple co-related components using a single configuration.

http

Templated 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.

http

Automatic Cleanup

Cleanup old snapshots automatically according to different retention policies.

http

Hooks

Perform some actions before and after backup or restore process using Stash Hooks.

http

Multiple Platforms 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.

http

Multiple Architectures Support

Stash supports multiple architectures. Stash docker images are platform aware. We use Docker manifest to build docker image for linux/amd64 linux/arm linux/arm64 architectures. Hence, whatever platforms you are using, you don't have to worry about the image version. Docker will automatically download the right image for you.

http

Deduplication

Stash will upload only the diff since last backup. It splits the targeted files into smaller blob using Content Defined Chunking (CDC) and upload only the modified blobs.

http

Encryption

Stash keeps all your data encrypted using AES-256. So, your data is protected event if it leaks from the backend.

http

Extensibility

You can extend Stash using Function and Task. Now, you can customize the backup and restore process. You can even backup your custom workloads that are not officially supported by Stash.

http

kubectl Plugin

Stah provides a kubectl plugin that provides some nifty features such as triggering instant backup, copy Repository into different namespace, clone workloads into a different namespace or cluster etc.

http

RBAC

Stash comes with minimal RBAC permissions to ensure your cluster security. We make sure that no user can use Stash to access the resources of an unauthenticated namespace.

http

Prometheus Monitoring

Stash provides rich Prometheus metrics for backup and restore process. You can use official Prometheus server or CoreOS Prometheus operator to monitor these metrics.
