Backup ZooKeeper using KubeStash Auto-Backup

KubeStash can automatically be configured to backup any ZooKeeper in your cluster. KubeStash enables cluster administrators to deploy backup blueprints ahead of time so database owners can easily backup any ZooKeeper database with a few annotations.

In this tutorial, we are going to show how you can configure a backup blueprint for ZooKeeper in your cluster and backup them with a few annotations.

Before You Begin

At first, you need to have a Kubernetes cluster, and the kubectl command-line tool must be configured to communicate with your cluster. If you do not already have a cluster, you can create one by using Minikube or Kind.
Install KubeDB in your cluster following the steps here.
Install KubeStash in your cluster following the steps here.
Install KubeStash kubectl plugin following the steps here.
If you are not familiar with how KubeStash backup and restore ZooKeeper, please check the following guide here.

You should be familiar with the following KubeStash concepts:

To keep everything isolated, we are going to use a separate namespace called demo throughout this tutorial.

$ kubectl create ns demo
namespace/demo created

Note: YAML files used in this tutorial are stored in docs/guides/zookeeper/backup/kubestash/auto-backup/examples directory of kubedb/docs repository.

Prepare Backend

We are going to store our backed up data into a s3 bucket. We have to create a Secret with necessary credentials and a BackupStorage CR to use this backend. If you want to use a different backend, please read the respective backend configuration doc from here.

Create Secret:

Let’s create a secret called s3-secret with access credentials to our desired GCS bucket,

$ echo -n '<your-aws-access-key-id-here>' > AWS_ACCESS_KEY_ID
$ echo -n '<your-aws-secret-access-key-here>' > AWS_SECRET_ACCESS_KEY
$ kubectl create secret generic -n demo s3-secret \
    --from-file=./AWS_ACCESS_KEY_ID \
    --from-file=./AWS_SECRET_ACCESS_KEY
secret/s3-secret created

Create BackupStorage:

Now, create a BackupStorage using this secret. Below is the YAML of BackupStorage CR we are going to create,

apiVersion: storage.kubestash.com/v1alpha1
kind: BackupStorage
metadata:
  name: s3-storage
  namespace: demo
spec:
  storage:
    provider: s3
    s3:
      endpoint: ap-south-1.linodeobjects.com
      bucket: rudro
      region: ap-south-1
      prefix: blueprint
      secretName: s3-secret
  usagePolicy:
    allowedNamespaces:
      from: All
  deletionPolicy: WipeOut

Let’s create the BackupStorage we have shown above,

$ kubectl apply -f https://github.com/kubedb/docs/raw/v2025.5.30/docs/guides/zookeeper/backup/kubestash/auto-backup/examples/backupstorage.yaml
backupstorage.storage.kubestash.com/s3-storage created

Now, we are ready to backup our database to our desired backend.

Create RetentionPolicy:

Now, let’s create a RetentionPolicy to specify how the old Snapshots should be cleaned up.

Below is the YAML of the RetentionPolicy object that we are going to create,

apiVersion: storage.kubestash.com/v1alpha1
kind: RetentionPolicy
metadata:
  name: demo-retention
  namespace: demo
spec:
  default: true
  failedSnapshots:
    last: 2
  maxRetentionPeriod: 2mo
  successfulSnapshots:
    last: 5
  usagePolicy:
    allowedNamespaces:
      from: All

Let’s create the above RetentionPolicy,

$ kubectl apply -f https://github.com/kubedb/docs/raw/v2025.5.30/docs/guides/zookeeper/backup/kubestash/auto-backup/examples/retentionpolicy.yaml
retentionpolicy.storage.kubestash.com/demo-retention created

Create Secret:

We also need to create a secret with a Restic password for backup data encryption.

Let’s create a secret called encrypt-secret with the Restic password,

$ echo -n 'changeit' > RESTIC_PASSWORD
$ kubectl create secret generic -n demo encrypt-secret \
    --from-file=./RESTIC_PASSWORD \
secret "encrypt-secret" created

Auto-backup with default configurations

In this section, we are going to backup a ZooKeeper of demo namespace. We are going to use the default configurations which will be specified in the BackupBlueprint CR.

Prepare Backup Blueprint

A BackupBlueprint allows you to specify a template for the Repository,Session or Variables of BackupConfiguration in a Kubernetes native way.

Now, we have to create a BackupBlueprint CR with a blueprint for BackupConfiguration object.

apiVersion: core.kubestash.com/v1alpha1
kind: BackupBlueprint
metadata:
  name: zookeeper-default-backup-blueprint
  namespace: demo
spec:
  usagePolicy:
    allowedNamespaces:
      from: All
  backupConfigurationTemplate:
    deletionPolicy: OnDelete
    backends:
      - name: s3-backend
        storageRef:
          namespace: demo
          name: s3-storage
        retentionPolicy:
          name: demo-retention
          namespace: demo
    sessions:
      - name: frequent-backup
        sessionHistoryLimit: 3
        scheduler:
          schedule: "*/5 * * * *"
          jobTemplate:
            backoffLimit: 1
        repositories:
          - name: default-blueprint
            backend: s3-backend
            directory: /default-blueprint
            encryptionSecret:
              name: encrypt-secret
              namespace: demo
        addon:
          name: zookeeper-addon
          tasks:
            - name: logical-backup

Here,

.spec.backupConfigurationTemplate.backends[*].storageRef refers our earlier created s3-storage backupStorage.
.spec.backupConfigurationTemplate.sessions[*].schedule specifies that we want to backup the database at 5 minutes interval.

Let’s create the BackupBlueprint we have shown above,

$ kubectl apply -f https://github.com/kubedb/docs/raw/v2025.5.30/docs/guides/zookeeper/backup/kubestash/auto-backup/examples/default-backupblueprint.yaml
backupblueprint.core.kubestash.com/zookeeper-default-backup-blueprint created

Now, we are ready to backup our ZooKeeper using few annotations.

Create Database

Now, we are going to create an ZooKeeper CR in demo namespace.

Below is the YAML of the ZooKeeper object that we are going to create,

apiVersion: kubedb.com/v1alpha2
kind: ZooKeeper
metadata:
  name: sample-zookeeper
  namespace: demo
  annotations:
    blueprint.kubestash.com/name: zookeeper-default-backup-blueprint
    blueprint.kubestash.com/namespace: demo
spec:
  version: "3.8.3"
  adminServerPort: 8080
  replicas: 3
  storage:
    resources:
      requests:
        storage: "1Gi"
    accessModes:
      - ReadWriteOnce
  deletionPolicy: "WipeOut"

Here,

.spec.annotations.blueprint.kubestash.com/name: zookeeper-default-backup-blueprint specifies the name of the BackupBlueprint that will use in backup.
.spec.annotations.blueprint.kubestash.com/namespace: demo specifies the name of the namespace where the BackupBlueprint resides.

Let’s create the ZooKeeper we have shown above,

$ kubectl apply -f https://github.com/kubedb/docs/raw/v2025.5.30/docs/guides/zookeeper/backup/kubestash/auto-backup/examples/sample-zookeeper.yaml
zookeeper.kubedb.com/sample-zookeeper created

Verify BackupConfiguration

If everything goes well, KubeStash should create a BackupConfiguration for our ZooKeeper in demo namespace and the phase of that BackupConfiguration should be Ready. Verify the BackupConfiguration object by the following command,

$ kubectl get backupconfiguration -n demo
NAME                          PHASE   PAUSED   AGE
appbinding-sample-zookeeper   Ready            2m50m

Now, let’s check the YAML of the BackupConfiguration.

$ kubectl get backupconfiguration -n demo appbinding-sample-zookeeper  -o yaml

apiVersion: core.kubestash.com/v1alpha1

          status: "True"
          type: InitialBackupTriggered
      name: frequent-backup
  targetFound: true

Notice the spec.backends, spec.sessions and spec.target sections, KubeStash automatically resolved those info from the BackupBluePrint and created above BackupConfiguration.

Verify BackupSession:

KubeStash triggers an instant backup as soon as the BackupConfiguration is ready. After that, backups are scheduled according to the specified schedule.

$ kubectl get backupsession -n demo -w
NAME                                                     INVOKER-TYPE          INVOKER-NAME                  PHASE       DURATION   AGE
appbinding-sample-zookeeper-frequent-backup-1726735844   BackupConfiguration   appbinding-sample-zookeeper   Succeeded   23s        6m40s

We can see from the above output that the backup session has succeeded. Now, we are going to verify whether the backed up data has been stored in the backend.

Verify Backup:

Once a backup is complete, KubeStash will update the respective Repository CR to reflect the backup. Check that the repository default-blueprint has been updated by the following command,

$ kubectl get repository -n demo default-blueprint
NAME                INTEGRITY   SNAPSHOT-COUNT   SIZE        PHASE   LAST-SUCCESSFUL-BACKUP   AGE
default-blueprint   true        1                1.559 KiB   Ready   80s                      7m32s

At this moment we have one Snapshot. Run the following command to check the respective Snapshot which represents the state of a backup run for an application.

$ kubectl get snapshots -n demo -l=kubestash.com/repo-name=default-blueprint
NAME                                                              REPOSITORY          SESSION           SNAPSHOT-TIME          DELETION-POLICY   PHASE       AGE
default-blueprint-appbinding-samgres-frequent-backup-1726736101   default-blueprint   frequent-backup   2024-09-19T08:55:01Z   Delete            Succeeded   7m48s

Note: KubeStash creates a Snapshot with the following labels:
kubestash.com/app-ref-kind: <target-kind>
kubestash.com/app-ref-name: <target-name>
kubestash.com/app-ref-namespace: <target-namespace>
kubestash.com/repo-name: <repository-name>
These labels can be used to watch only the Snapshots related to our target Database or Repository.

If we check the YAML of the Snapshot, we can find the information about the backed up components of the Database.

KubeStash uses zk-dump-go to perform backups of target ZooKeeper. Therefore, the component name for logical backups is set as dump.

Now, if we navigate to the s3 bucket, we will see the backed up data stored in the blueprint/default-blueprint/repository/v1/frequent-backup/dump directory. KubeStash also keeps the backup for Snapshot YAMLs, which can be found in the blueprint/default-blueprint/snapshots directory.

Note: KubeStash stores all dumped data encrypted in the backup directory, meaning it remains unreadable until decrypted.

Auto-backup with custom configurations

In this section, we are going to backup a ZooKeeper of demo namespace. We are going to use the custom configurations which will be specified in the BackupBlueprint CR.

Prepare Backup Blueprint

A BackupBlueprint allows you to specify a template for the Repository,Session or Variables of BackupConfiguration in a Kubernetes native way.

Now, we have to create a BackupBlueprint CR with a blueprint for BackupConfiguration object.

apiVersion: core.kubestash.com/v1alpha1
kind: BackupBlueprint
metadata:
  name: zookeeper-customize-backup-blueprint
  namespace: demo
spec:
  usagePolicy:
    allowedNamespaces:
      from: Same
  backupConfigurationTemplate:
    deletionPolicy: OnDelete
    backends:
      - name: s3-backend
        storageRef:
          namespace: demo
          name: s3-storage
        retentionPolicy:
          name: demo-retention
          namespace: demo
    sessions:
      - name: frequent-backup
        sessionHistoryLimit: 3
        scheduler:
          schedule: ${schedule}
          jobTemplate:
            backoffLimit: 1
        repositories:
          - name: ${repoName}
            backend: s3-backend
            directory: ${namespace}/${targetName}
            encryptionSecret:
              name: encrypt-secret
              namespace: demo
        addon:
          name: zookeeper-addon
          tasks:
            - name: logical-backup

Note that we have used some variables (format: ${<variable name>}) in different fields. KubeStash will substitute these variables with values from the respective target’s annotations. You’re free to use any variables you like.

Here,

.spec.backupConfigurationTemplate.backends[*].storageRef refers our earlier created s3-storage backupStorage.
.spec.backupConfigurationTemplate.sessions[*]:
- .schedule defines ${schedule} variable, which determines the time interval for the backup.
- .repositories[*].name defines the ${repoName} variable, which specifies the name of the backup Repository.
- .repositories[*].directory defines two variables, ${namespace} and ${targetName}, which are used to determine the path where the backup will be stored.
- .addon.tasks[*].params.args defines ${targetedDatabase} variable, which identifies a single database to backup.

Let’s create the BackupBlueprint we have shown above,

$ kubectl apply -f https://github.com/kubedb/docs/raw/v2025.5.30/docs/guides/zookeeper/backup/kubestash/auto-backup/examples/customize-backupblueprint.yaml
backupblueprint.core.kubestash.com/zookeeper-customize-backup-blueprint created

Now, we are ready to backup our ZooKeeper using few annotations. You can check available auto-backup annotations for a databases from here.

Create Database

Now, we are going to create an ZooKeeper CR in demo namespace.

Below is the YAML of the ZooKeeper object that we are going to create,

apiVersion: kubedb.com/v1alpha2
kind: ZooKeeper
metadata:
  name: sample-zookeeper-2
  namespace: demo
  annotations:
    blueprint.kubestash.com/name: zookeeper-customize-backup-blueprint
    blueprint.kubestash.com/namespace: demo
    variables.kubestash.com/schedule: "*/10 * * * *"
    variables.kubestash.com/repoName: customize-blueprint
    variables.kubestash.com/namespace: demo
    variables.kubestash.com/targetName: sample-zookeeper-2
    variables.kubestash.com/targetedDatabase: zookeeper
spec:
  version: "3.8.3"
  adminServerPort: 8080
  replicas: 3
  storage:
    resources:
      requests:
        storage: "1Gi"
    accessModes:
      - ReadWriteOnce
  deletionPolicy: "WipeOut"

Notice the metadata.annotations field, where we have defined the annotations related to the automatic backup configuration. Specifically, we’ve set the BackupBlueprint name as zookeeper-customize-backup-blueprint and the namespace as demo. We have also provided values for the blueprint template variables, such as the backup schedule, repositoryName, namespace, targetName, and targetedDatabase. These annotations will be used to create a BackupConfiguration for this ZooKeeper database.

Let’s create the ZooKeeper we have shown above,

$ kubectl apply -f https://github.com/kubedb/docs/raw/v2025.5.30/docs/guides/zookeeper/backup/kubestash/auto-backup/examples/sample-zookeeper-2.yaml

Notice the spec.backends, spec.sessions and spec.target sections, KubeStash automatically resolved those info from the BackupBluePrint and created above BackupConfiguration.

Verify BackupSession:

KubeStash triggers an instant backup as soon as the BackupConfiguration is ready. After that, backups are scheduled according to the specified schedule.

$ kubectl get backupsession -n demo -w
NAME                                                        INVOKER-TYPE          INVOKER-NAME                   PHASE       DURATION   AGE
appbinding-sample-zookeeper-2-frequent-backup-1726742400    BackupConfiguration   appbinding-sample-zookeeper     Succeeded   58s        112s

We can see from the above output that the backup session has succeeded. Now, we are going to verify whether the backed up data has been stored in the backend.

Verify Backup:

Once a backup is complete, KubeStash will update the respective Repository CR to reflect the backup. Check that the repository customize-blueprint has been updated by the following command,

$ kubectl get repository -n demo customize-blueprint
NAME                         INTEGRITY   SNAPSHOT-COUNT   SIZE    PHASE   LAST-SUCCESSFUL-BACKUP   AGE
customize-blueprint          true        1                806 B   Ready   8m27s                    9m18s

At this moment we have one Snapshot. Run the following command to check the respective Snapshot which represents the state of a backup run for an application.

$ kubectl get snapshots -n demo -l=kubestash.com/repo-name=customize-blueprint
NAME                                                              REPOSITORY            SESSION           SNAPSHOT-TIME          DELETION-POLICY   PHASE       AGE
customize-blueprint-appbinding-ser-2-frequent-backup-1726742400   customize-blueprint   frequent-backup   2024-09-19T10:40:01Z   Delete            Succeeded   6m19s

Note: KubeStash creates a Snapshot with the following labels:
kubedb.com/db-version: <db-version>
kubestash.com/app-ref-kind: <target-kind>
kubestash.com/app-ref-name: <target-name>
kubestash.com/app-ref-namespace: <target-namespace>
kubestash.com/repo-name: <repository-name>
These labels can be used to watch only the Snapshots related to our target Database or Repository.

If we check the YAML of the Snapshot, we can find the information about the backed up components of the Database.

KubeStash uses zk-dump-go to perform backups of target ZooKeeper. Therefore, the component name for logical backups is set as dump.

Now, if we navigate to the s3 bucket, we will see the backed up data stored in the blueprint/demo/sample-zookeeper-2/repository/v1/frequent-backup/dump directory. KubeStash also keeps the backup for Snapshot YAMLs, which can be found in the blueprint/demo/sample-zookeeper-2/snapshots directory.

Note: KubeStash stores all dumped data encrypted in the backup directory, meaning it remains unreadable until decrypted.
