Backups

Backups in Kubernetes should be performed on two levels:

  • Backup of the cluster state
  • Backup of volumes used in the cluster

Backup of the cluster state

etcd is the data backend for NETWAYS Managed Kubernetes. This should be backed up regularly.
If a cluster becomes damaged or misconfigured, it can be restored from an existing backup.

In NETWAYS Managed Kubernetes you can set up periodic etcd backups. To configure them, click Set etcd backup interval in the context menu of the respective cluster.

Backup costs

Backups for NETWAYS Managed Kubernetes incur costs.

The desired backup interval can be chosen from the following options:

  • Every 5 minutes
  • Every hour
  • Every night
  • Disabled [Default]

The backups are stored in the S3 object storage of the respective Kubernetes project. The credentials for this can be found in the Object Storage menu of the corresponding project.

Backup of volumes used in the cluster

In NETWAYS Managed Kubernetes you can also configure backups on the volume level in addition to etcd backups of the cluster state.

These protect against data loss for so‑called stateful applications.

To configure backups for a volume, click Configure Backup in the context menu of the respective volume.

The backup frequency can be set in 1‑day increments.
