# Backups
## vmbackupmanager
You can check vmbackupmanager [documentation](https://docs.victoriametrics.com/vmbackupmanager.html). It contains a description of the service and its features. This documentation covers vmbackumanager integration in vmoperator
### vmbackupmanager is a part of VictoriaMetrics Enterprise offer
*Before using it, you must have signed contract and accept EULA https://victoriametrics.com/assets/VM_EULA.pdf*
## Usage examples
`VMSingle` and `VMCluster` has built-in backup configuration, it uses `vmbackupmanager` - proprietary tool for backups.
It supports incremental backups (hourly, daily, weekly, monthly) with popular object storages (aws s3, google cloud storage).
The configuration example is the following:
```yaml
---
apiVersion: v1
kind: Secret
metadata:
name: remote-storage-keys
type: Opaque
stringData:
credentials: |-
[default]
aws_access_key_id = your_access_key_id
aws_secret_access_key = your_secret_access_key
---
apiVersion: operator.victoriametrics.com/v1beta1
kind: VMSingle
metadata:
name: example-vmsingle
spec:
# Add fields here
retentionPeriod: "1"
vmBackup:
# This is Enterprise Package feature you need to have signed contract to use it
# and accept the EULA https://victoriametrics.com/assets/VM_EULA.pdf
acceptEULA: true
destination: "s3://your_bucket/folder"
credentialsSecret:
name: remote-storage-keys
key: credentials
---
apiVersion: operator.victoriametrics.com/v1beta1
kind: VMCluster
metadata:
name: example-vmcluster-persistent
spec:
retentionPeriod: "4"
replicationFactor: 2
vmstorage:
replicaCount: 2
vmBackup:
# This is Enterprise Package feature you need to have signed contract to use it
# and accept the EULA https://victoriametrics.com/assets/VM_EULA.pdf
acceptEULA: true
destination: "s3://your_bucket/folder"
credentialsSecret:
name: remote-storage-keys
key: credentials
```
NOTE: for cluster version operator adds suffix for destination: `"s3://your_bucket/folder"`, it becomes `"s3://your_bucket/folder/$(POD_NAME)"`.
It's needed to make consistent backups for each storage node.
You can read more about backup configuration options and mechanics [here](https://docs.victoriametrics.com/vmbackup.html)
Possible configuration options for backup crd can be found at [link](https://docs.victoriametrics.com/operator/api.html#vmbackup)
## Restoring backups
There are several ways to restore with [vmrestore](https://docs.victoriametrics.com/vmrestore.html) or [vmbackupmanager](https://docs.victoriametrics.com/vmbackupmanager.html).
### Manually mounting disk
You have to stop `VMSingle` by scaling it replicas to zero and manually restore data to the database directory.
Steps:
1. edit `VMSingle` CRD, set replicaCount: 0
1. wait until database stops
1. ssh to some server, where you can mount `VMSingle` disk and mount it manually
1. restore files with `vmrestore`
1. umount disk
1. edit `VMSingle` CRD, set replicaCount: 1
1. wait database start
### Using VMRestore init container
1. add init container with vmrestore command to `VMSingle` CRD, example:
```yaml
apiVersion: operator.victoriametrics.com/v1beta1
kind: VMSingle
metadata:
name: vmsingle-restored
namespace: monitoring-system
spec:
initContainers:
- name: vmrestore
image: victoriametrics/vmrestore:latest
volumeMounts:
- mountPath: /victoria-metrics-data
name: data
- mountPath: /etc/vm/creds
name: secret-remote-storage-keys
readOnly: true
args:
- -storageDataPath=/victoria-metrics-data
- -src=s3://your_bucket/folder/latest
- -credsFilePath=/etc/vm/creds/credentials
vmBackup:
# This is Enterprise Package feature you need to have signed contract to use it
# and accept the EULA https://victoriametrics.com/assets/VM_EULA.pdf
acceptEULA: true
destination: "s3://your_bucket/folder"
extraArgs:
runOnStart: "true"
image:
repository: victoriametrics/vmbackupmanager
tag: v1.83.0-enterprise
credentialsSecret:
name: remote-storage-keys
key: credentials
```
1. apply it, and db will be restored from s3
1. remove initContainers and apply crd.
Note that using `VMRestore` will require adjusting `src` for each pod because restore will be handled per-pod.
### Using VMBackupmanager init container
Using VMBackupmanager restore in Kubernetes environment is described [here](https://docs.victoriametrics.com/vmbackupmanager.html#how-to-restore-in-kubernetes).
Advantages of using `VMBackupmanager` include:
- automatic adjustment of `src` for each pod when backup is requested
- graceful handling of case when no restore is required - `VMBackupmanager` will exit with successful status code and won't prevent pod from starting
