Configure a storage location where all backups are saved by default. You will have the option to override this with each backup, but will be limited to using an S3-compatible object store.

Only one storage location can be configured at the operator level.

• Storage Location Configuration
  • No Default Storage Location
  • S3-compatible Object Store
  • Use an existing StorageClass
  • Use an existing PersistentVolume
• Encryption
• Example values.yaml for the rancher-backup Helm Chart

Storage Location Configuration

No Default Storage Location

You can choose to not have any operator-level storage location configured. If you select this option, you must configure an S3-compatible object store as the storage location for each individual backup.

S3-compatible Object Store

Existing StorageClass

Installing the rancher-backup chart by selecting the StorageClass option will create a Persistent Volume Claim (PVC), and Kubernetes will in turn dynamically provision a Persistent Volume (PV) where all the backups will be saved by default.

For information about creating storage classes refer to this section.

Important It is highly recommended to use a StorageClass with a reclaim policy of “Retain”. Otherwise if the PVC created by the rancher-backup chart gets deleted (either during app upgrade, or accidentally), the PV will get deleted too, which means all backups saved in it will get deleted.
If no such StorageClass is available, after the PV is provisioned, make sure to edit its reclaim policy and set it to “Retain” before storing backups in it.

Existing Persistent Volume

Select an existing Persistent Volume (PV) that will be used to store your backups. For information about creating PersistentVolumes in Rancher, refer to this section.

Important It is highly recommended to use a Persistent Volume with a reclaim policy of “Retain”. Otherwise if the PVC created by the rancher-backup chart gets deleted (either during app upgrade, or accidentally), the PV will get deleted too, which means all backups saved in it will get deleted.

Example values.yaml for the rancher-backup Helm Chart

This values.yaml file can be used to configure rancher-backup operator when the Helm CLI is used to install it.

For more information about values.yaml files and configuring Helm charts during installation, refer to the Helm documentation.
