Backblaze B2
Stash supports Backblaze B2 as a backend. This tutorial will show you how to configure Restic and storage Secret for B2 backend.
Create Storage Secret
To configure storage secret for this backend, following secret keys are needed:
| Key | Description |
|---|---|
RESTIC_PASSWORD | Required. Password used to encrypt snapshots by restic |
B2_ACCOUNT_ID | Required. Backblaze B2 account id |
B2_ACCOUNT_KEY | Required. Backblaze B2 account key |
Create storage secret as below,
$ echo -n 'changeit' > RESTIC_PASSWORD
$ echo -n '<your-b2-account-id>' > B2_ACCOUNT_ID
$ echo -n '<your-b2-account-key>' > B2_ACCOUNT_KEY
$ kubectl create secret generic b2-secret \
--from-file=./RESTIC_PASSWORD \
--from-file=./B2_ACCOUNT_ID \
--from-file=./B2_ACCOUNT_KEY
secret "b2-secret" created
Verify that the secret has been created with respective keys,
$ kubectl get secret b2-secret -o yaml
apiVersion: v1
data:
B2_ACCOUNT_ID: PHlvdXItYXp1cmUtc3RvcmFnZS1hY2NvdW50LWtleT4=
B2_ACCOUNT_KEY: PHlvdXItYXp1cmUtc3RvcmFnZS1hY2NvdW50LW5hbWU+

Configure Restic
Now, you have to configure Restic crd to use Backblaze B2. You have to provide previously created storage secret in spec.backend.storageSecretName field.
Following parameters are available for B2 backend.

b2.bucket | Required. Name of B2 bucket |
b2.prefix | Optional. Path prefix into bucket where repository will be created. |
Below, the YAML for Restic crd configured to use Backblaze B2.
apiVersion: stash.appscode.com/v1alpha1
kind: Restic
metadata:
name: b2-restic
namespace: default
spec:
selector:
matchLabels:
app: b2-restic
fileGroups:
- path: /source/data
retentionPolicyName: 'keep-last-5'
backend:

bucket: stash-qa
prefix: demo
storageSecretName: b2-secret
schedule: '@every 1m'
volumeMounts:
- mountPath: /source/data
