adfinissygroup/back8sup repository overview
back8sup
A simple way to backup your kubernetes resources
Why?
In some cases, using Velero with an S3 storage provider is overkill.
This script keeps things very basic and simple, and makes it easy to backup your Kubernetes metadata quickly by using your default StorageClass.
Deployment with Helm
helm repo add adfinis https://charts.adfinis.com
helm install back8sup adfinis/back8sup
