Backup & Restore Metrics
Learn how to backup and restore metrics into groundcover metrics storage
groundcover uses VictoriaMetrics as its underlying metrics storage solution. As such, groundcover integrates seamlessly with VictoriaMetrics vmbackup and vmrestore tools.
- port-forward groundcover's VictoriaMetrics service object
kubectl get svc -n groundcover | grep "victoria-metrics"
# Identify the victoria-metrics service object name
kubectl port-forward svc/{victoria-metrics-service-object-name} \
-n groundcover 8428:8428
- Run the
vmbackuputility, in this example we'll set the destination to an AWS S3 bucket, but more providers are supported
./vmbackup -credsFilePath={aws credentials path} \
-storageDataPath=</path/to/victoria-metrics-data> \
-snapshot.createURL=http://localhost:8428/snapshot/create \
-dst=s3://<bucket>/<path/to/backup>
vmbackup automatically uses incremental backup strategy if the destination contains an existing backup
- Scale down VictoriaMetrics statefulSet (VictoriaMetrics must be offline during restorations)
kubectl scale sts {release name}-victoria-metrics --replicas=0
- Get the VictoriaMetrics PVC name
kubectl get pvc -n groundcover | grep victoria-metrics
- Create the following Kubernetes Job manifest
vm-restore.yaml
Make sure you replace {VICTORIA METRICS PVC NAME} with the fetched pvc name
apiVersion: v1
kind: ServiceAccount
metadata:
name: vm-restore
annotations:
eks.amazonaws.com/role-arn: XXXXX # role with permissions to write to the bucket

apiVersion: batch/v1
kind: Job

volumes:
- name: vmstorage-volume
persistentVolumeClaim:
claimName: "{VICTORIA METRICS PVC NAME}"
containers:
- name: vm-restore
image: victoriametrics/vmrestore
imagePullPolicy: IfNotPresent
volumeMounts:
- mountPath: /storage
name: vmstorage-volume
command:
- /bin/sh
- -c
- /vmrestore-prod -src=s3://<bucket>/<path/to/backup> -storageDataPath=/storage
- Deploy the job and wait for completion
kubectl apply -f vm-restore.yaml -n groundcover
- Once completed, scale up groundcover's VictoriaMetrics instance
kubectl scale sts {release name}-victoria-metrics --replicas=1
