This guide walks through the process of backing up a Kubernetes cluster using Restic with Velero. Velero is a command-line tool that backs up Kubernetes clusters and restores them in case of loss. Velero includes a command-line interface and server-side component that runs inside of your Kubernetes cluster.
Velero lets you:
Take backups of your cluster and restore them in case of loss.
Migrate cluster resources to other clusters.
Replicate your production cluster to development and testing clusters.
Complete Velero Prerequisites and install the CLI: docs
Create a Storj Tardigrade account: docs
Created a project in the Tardigrade account: docs
Create an API key for the project: docs
Setup a Tardigrade Uplink CLI and create an access grant for the project: docs
Create a Tardigrade bucket where Velero will store the backups: docs
Install Velero with Storj plugin
$ velero install --provider gcp \--plugins jessgreb01/velero-plugin-for-storj:v0.0.2 \--bucket $BUCKET \--backup-location-config accessGrant=$ACCESS \--no-secret
Perform a backup:
$ velero backup create $BACKUP_NAME
Perform a restore:
$ velero restore create $RESTORE_NAME --from-backup $BACKUP_NAME
The complete Velero documentation is located here.
Because Tardigrade is a globally distributed hot object store, you can store and recover your Kubernetes volumes from anywhere in the world, instantly, without having to replicate data across regions. For DevOps managers, this can mean better resilience for your cluster, reduced global RTO (recovery time objective), cost-savings, and improved native security over centralized alternatives.
In the example below, we can see a Disaster Recovery scenario where we might need to migrate into a new cluster:
In this scenario, Cluster B is restored from the backup of A and reconstituting the Kubernetes volume in the cluster.
