Stash
Stash by AppsCode is a cloud native data backup and recovery solution for Kubernetes workloads. If you are running production workloads in Kubernetes, you might want to take backup of your disks, databases etc. 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. User may even extend Stash via addons for any custom workload.
