# 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 ESA https://victoriametrics.com/legal/esa/*
|
|
|
|
## 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 ESA https://victoriametrics.com/legal/esa/
|
|
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 ESA https://victoriametrics.com/legal/esa/
|
|
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 ESA https://victoriametrics.com/legal/esa/
|
|
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
|
