# vmbackupmanager
|
||
|
||
***vmbackupmanager is a part of [enterprise package](https://docs.victoriametrics.com/enterprise/).
|
||
It is available for download and evaluation at [releases page](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/latest).
|
||
See how to request a free trial license [here](https://victoriametrics.com/products/enterprise/trial/).***
|
||
|
||
The VictoriaMetrics backup manager automates regular backup procedures. It supports the following backup intervals: **hourly**, **daily**, **weekly** and **monthly**.
|
||
Multiple backup intervals may be configured simultaneously. I.e. the backup manager creates hourly backups every hour, while it creates daily backups every day, etc.
|
||
Backup manager must have read access to the storage data, so best practice is to install it on the same machine (or as a sidecar) where the storage node is installed.
|
||
The backup service makes a backup every hour and puts it to the latest folder and then copies data to the folders
|
||
which represent the backup intervals (hourly, daily, weekly and monthly)
|
||
|
||
The required flags for running the service are as follows:
|
||
|
||
* `-license` or `-licenseFile` . See [these docs](https://docs.victoriametrics.com/enterprise/#running-victoriametrics-enterprise).
|
||
* `-storageDataPath` - path to VictoriaMetrics or vmstorage data path to make backup from.
|
||
* `-snapshot.createURL` - VictoriaMetrics creates snapshot URL which will automatically be created during backup. Example: http://victoriametrics:8428/snapshot/create
|
||
* `-dst` - backup destination at [the supported storage types](https://docs.victoriametrics.com/vmbackup/#supported-storage-types).
|
||
* `-credsFilePath` - path to file with GCS or S3 credentials. Credentials are loaded from default locations if not set.
|
||
See [https://cloud.google.com/iam/docs/creating-managing-service-account-keys](https://cloud.google.com/iam/docs/creating-managing-service-account-keys)
|
||
and [https://docs.aws.amazon.com/general/latest/gr/aws-security-credentials.html](https://docs.aws.amazon.com/general/latest/gr/aws-security-credentials.html).
|
||
|
||
Backup schedule is controlled by the following flags:
|
||
|
||
* `-disableHourly` - disable hourly run. Default false
|
||
* `-disableDaily` - disable daily run. Default false
|
||
* `-disableWeekly` - disable weekly run. Default false
|
||
* `-disableMonthly` - disable monthly run. Default false
|
||
|
||
By default, all flags are turned on and Backup Manager backups data every hour for every interval (hourly, daily, weekly and monthly).
|
||
|
||
The backup manager creates the following directory hierarchy at `-dst`:
|
||
|
||
* `/latest/` - contains the latest backup
|
||
* `/hourly/` - contains hourly backups. Each backup is named as `YYYY-MM-DD:HH`
|
||
* `/daily/` - contains daily backups. Each backup is named as `YYYY-MM-DD`
|
||
* `/weekly/` - contains weekly backups. Each backup is named as `YYYY-WW`
|
||
* `/monthly/` - contains monthly backups. Each backup is named as `YYYY-MM`
|
||
|
||
To get the full list of supported flags please run the following command:
|
||
|
||
```sh
|
||
./vmbackupmanager --help
|
||
```
|
||
|
||
The service creates a **full** backup each run. This means that the system can be restored fully
|
||
from any particular backup using [vmrestore](https://docs.victoriametrics.com/vmrestore/).
|
||
Backup manager uploads only the data that has been changed or created since the most recent backup
|
||
([incremental backup](https://docs.victoriametrics.com/vmbackup/#incremental-backups)).
|
||
This reduces the consumed network traffic and the time needed for performing the backup.
|
||
See [this article](https://medium.com/@valyala/speeding-up-backups-for-big-time-series-databases-533c1a927883) for details.
|
||
|
||
*Please take into account that the first backup upload could take a significant amount of time as it needs to upload all the data.*
|
||
|
||
There are two flags which could help with performance tuning:
|
||
|
||
* `-maxBytesPerSecond` - the maximum upload speed. There is no limit if it is set to 0
|
||
* `-concurrency` - The number of concurrent workers. Higher concurrency may improve upload speed (default 10)
|
||
|
||
## Example of Usage
|
||
|
||
GCS and cluster version. You need to have a credentials file in json format with following structure:
|
||
|
||
credentials.json
|
||
|
||
```json
|
||
{
|
||
"type": "service_account",
|
||
"project_id": "<project>",
|
||
"private_key_id": "",
|
||
"private_key": "-----BEGIN PRIVATE KEY-----\-----END PRIVATE KEY-----\n",
|
||
"client_email": "test@<project>.iam.gserviceaccount.com",
|
||
"client_id": "",
|
||
"auth_uri": "https://accounts.google.com/o/oauth2/auth",
|
||
"token_uri": "https://oauth2.googleapis.com/token",
|
||
"auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
|
||
"client_x509_cert_url": "https://www.googleapis.com/robot/v1/metadata/x509/test%40<project>.iam.gserviceaccount.com"
|
||
}
|
||
|
||
```
|
||
|
||
Backup manager launched with the following configuration:
|
||
|
||
```sh
|
||
export NODE_IP=192.168.0.10
|
||
export VMSTORAGE_ENDPOINT=http://127.0.0.1:8428
|
||
./vmbackupmanager -dst=gs://vmstorage-data/$NODE_IP -credsFilePath=credentials.json -storageDataPath=/vmstorage-data -snapshot.createURL=$VMSTORAGE_ENDPOINT/snapshot/create -eula
|
||
```
|
||
|
||
Expected logs in vmbackupmanager:
|
||
|
||
```sh
|
||
info lib/backup/actions/backup.go:131 server-side copied 81 out of 81 parts from GCS{bucket: "vmstorage-data", dir: "192.168.0.10//latest/"} to GCS{bucket: "vmstorage-data", dir: "192.168.0.10//weekly/2020-34/"} in 2.549833008s
|
||
info lib/backup/actions/backup.go:169 backed up 853315 bytes in 2.882 seconds; deleted 0 bytes; server-side copied 853315 bytes; uploaded 0 bytes
|
||
```
|
||
|
||
Expected logs in vmstorage:
|
||
|
||
```sh

|
||
```
|
||
|
||
The result on the GCS bucket
|
||
|
||
* The root folder
|
||
|
||
|
||
|
||
* The latest folder
|
||
|
||
|
||
|
||
`vmbackupmanager` uses [smart backups](https://docs.victoriametrics.com/vmbackup/#smart-backups) technique in order
|
||
to accelerate backups and save both data transfer costs and data copying costs. This includes server-side copy of already existing
|
||
objects. Typical object storage systems implement server-side copy by creating new names for already existing objects.
|
||
This is very fast and efficient. Unfortunately there are systems such as [S3 Glacier](https://aws.amazon.com/s3/storage-classes/glacier/),
|
||
which perform full object copy during server-side copying. This may be slow and expensive.
|
||
|
||
Please, see [vmbackup docs](https://docs.victoriametrics.com/vmbackup/#advanced-usage) for more examples of authentication with different
|
||
storage types.
|
||
|
||
## Backup Retention Policy
|
||
|
||
Backup retention policy is controlled by:
|
||
|
||
* `-keepLastHourly` - keep the last N hourly backups. Disabled by default
|
||
* `-keepLastDaily` - keep the last N daily backups. Disabled by default
|
||
* `-keepLastWeekly` - keep the last N weekly backups. Disabled by default
|
||
* `-keepLastMonthly` - keep the last N monthly backups. Disabled by default
|
||
|
||
> *Note*: 0 value in every keepLast flag results into deletion of ALL backups for particular type (hourly, daily, weekly and monthly)
|
||
|
||
> *Note*: retention policy does not enforce removing previous versions of objects in object storages such if versioning is enabled. See [these docs](https://docs.victoriametrics.com/vmbackup/#permanent-deletion-of-objects-in-s3-compatible-storages) for more details.
|
||
|
||
Let’s assume we have a backup manager collecting daily backups for the past 10 days.
|
||
|
||
|
||
|
||
We enable backup retention policy for backup manager by using following configuration:
|
||
|
||
```sh
|
||
export NODE_IP=192.168.0.10
|
||
export VMSTORAGE_ENDPOINT=http://127.0.0.1:8428
|
||
./vmbackupmanager -dst=gs://vmstorage-data/$NODE_IP -credsFilePath=credentials.json -storageDataPath=/vmstorage-data -snapshot.createURL=$VMSTORAGE_ENDPOINT/snapshot/create
|
||
-keepLastDaily=3 -eula
|
||
```
|
||
|
||
Expected logs in backup manager on start:
|
||
|
||
```sh
|
||
info lib/logger/flag.go:20 flag "keepLastDaily" = "3"
|
||
```
|
||
|
||
Expected logs in backup manager during retention cycle:
|
||
|
||
```sh
|
||
info app/vmbackupmanager/retention.go:106 daily backups to delete [daily/2021-02-13 daily/2021-02-12 daily/2021-02-11 daily/2021-02-10 daily/2021-02-09 daily/2021-02-08 daily/2021-02-07]
|
||
```
|
||
|
||
The result on the GCS bucket. We see only 3 daily backups:
|
||
|
||
[retention policy daily after retention cycle](vmbackupmanager_rp_daily_2.webp "retention policy daily after retention cycle")
|
||
|
||
### Protection backups against deletion by retention policy
|
||
|
||
You can protect any backup against deletion by retention policy with the `vmbackupmanager backups lock` command.
|
||
|
||
For instance:
|
||
|
||
```sh
|
||
./vmbackupmanager backup lock daily/2021-02-13 -dst=<DST_PATH> -storageDataPath=/vmstorage-data -eula
|
||
```
|
||
|
||
After that the backup won't be deleted by retention policy.
|
||
You can view the `locked` attribute in backup list:
|
||
|
||
```sh
|
||
./vmbackupmanager backup list -dst=<DST_PATH> -storageDataPath=/vmstorage-data -eula
|
||
```
|
||
|
||
To remove protection, you can use the command `vmbackupmanager backups unlock`.
|
||
|
||
For example:
|
||
|
||
```sh
|
||
./vmbackupmanager backup unlock daily/2021-02-13 -dst=<DST_PATH> -storageDataPath=/vmstorage-data -eula
|
||
```
|
||
|
||
## API methods

|
||
|
||
## CLI
|
||
|
||
`vmbackupmanager` exposes CLI commands to work with [API methods](#api-methods) without external dependencies.
|
||
|
||
Supported commands:
|
||
```sh
|
||
vmbackupmanager backup
|
||
|
||
vmbackupmanager backup list
|
||
List backups in remote storage
|
||
|
||
vmbackupmanager backup lock
|
||
Locks backup in remote storage against deletion
|
||
|
||
vmbackupmanager backup unlock
|
||
Unlocks backup in remote storage for deletion
|
||
|
||
vmbackupmanager restore
|
||
Restore backup specified by restore mark if it exists
|
||
|
||
vmbackupmanager restore get
|
||
Get restore mark if it exists
|
||
|
||
vmbackupmanager restore delete
|
||
Delete restore mark if it exists
|
||
|
||
vmbackupmanager restore create [backup_name]
|
||
Create restore mark
|
||
```
|
||
|
||
By default, CLI commands are using `http://127.0.0.1:8300` endpoint to reach `vmbackupmanager` API.
|
||
It can be changed by using flag:
|
||
```
|
||
-apiURL string
|
||
vmbackupmanager address to perform API requests (default "http://127.0.0.1:8300")
|
||
```
|
||
|
||
### Backup commands
|
||
|
||
`vmbackupmanager backup list` lists backups in remote storage:
|
||
```sh
|
||
$ ./vmbackupmanager backup list
|
||
[{"name":"daily/2023-04-07","size_bytes":318837,"size":"311.4ki","created_at":"2023-04-07T16:15:07+00:00"},{"name":"hourly/2023-04-07:11","size_bytes":318837,"size":"311.4ki","created_at":"2023-04-07T16:15:06+00:00"},{"name":"latest","size_bytes":318837,"size":"311.4ki","created_at":"2023-04-07T16:15:04+00:00"},{"name":"monthly/2023-04","size_bytes":318837,"size":"311.4ki","created_at":"2023-04-07T16:15:10+00:00"},{"name":"weekly/2023-14","size_bytes":318837,"size":"311.4ki","created_at":"2023-04-07T16:15:09+00:00"}]
|
||
```
|
||
|
||
### Restore commands
|
||
|
||
Restore commands are used to create, get and delete restore mark.
|
||
Restore mark is used by `vmbackupmanager` to store backup name to restore when running restore.
|
||
|
||
|
||
Create restore mark:
|
||
```sh
|
||
$ ./vmbackupmanager restore create daily/2022-10-06
|
||
```
|
||
|
||
Get restore mark if it exists:
|
||
```sh
|
||
$ ./vmbackupmanager restore get
|
||
{"backup":"daily/2022-10-06"}
|
||
```
|
||
|
||
Delete restore mark if it exists:
|
||
```sh
|
||
$ ./vmbackupmanager restore delete
|
||
```
|
||
|
||
Perform restore:
|
||
```sh
|
||
$ /vmbackupmanager-prod restore -dst=gs://vmstorage-data/$NODE_IP -credsFilePath=credentials.json -storageDataPath=/vmstorage-data
|
||
```
|
||
Note that `vmsingle` or `vmstorage` should be stopped before performing restore.
|
||
|
||
If restore mark doesn't exist at `storageDataPath`(restore wasn't requested) `vmbackupmanager restore` will exit with successful status code.
|
||
|
||
### How to restore backup via CLI
|
||
|
||
1. Run `vmbackupmanager backup list` to get list of available backups:
|
||
```sh
|
||
$ /vmbackupmanager-prod backup list
|
||
[{"name":"daily/2023-04-07","size_bytes":318837,"size":"311.4ki","created_at":"2023-04-07T16:15:07+00:00"},{"name":"hourly/2023-04-07:11","size_bytes":318837,"size":"311.4ki","created_at":"2023-04-07T16:15:06+00:00"},{"name":"latest","size_bytes":318837,"size":"311.4ki","created_at":"2023-04-07T16:15:04+00:00"},{"name":"monthly/2023-04","size_bytes":318837,"size":"311.4ki","created_at":"2023-04-07T16:15:10+00:00"},{"name":"weekly/2023-14","size_bytes":318837,"size":"311.4ki","created_at":"2023-04-07T16:15:09+00:00"}]
|
||
```
|
||
1. Run `vmbackupmanager restore create` to create restore mark:
|
||
- Use relative path to backup to restore from currently used remote storage:
|
||
```sh
|
||
$ /vmbackupmanager-prod restore create daily/2023-04-07
|
||
```
|
||
- Use full path to backup to restore from any remote storage:
|
||
```sh
|
||
$ /vmbackupmanager-prod restore create azblob://test1/vmbackupmanager/daily/2023-04-07
|
||
```
|
||
1. Stop `vmstorage` or `vmsingle` node
|
||
1. Run `vmbackupmanager restore` to restore backup:
|
||
```sh
|
||
$ /vmbackupmanager-prod restore -credsFilePath=credentials.json -storageDataPath=/vmstorage-data
|
||
```
|
||
1. Start `vmstorage` or `vmsingle` node
|
||
|
||
|
||
### How to restore in Kubernetes
|
||
|
||
1. Ensure there is an init container with `vmbackupmanager restore` in `vmstorage` or `vmsingle` pod.
|
||
For [VictoriaMetrics operator](https://docs.victoriametrics.com/operator/) deployments it is required to add:
|
||
```yaml
|
||
vmbackup:
|
||
restore:
|
||
onStart:
|
||
enabled: "true"
|
||
```
|
||
See operator `VMStorage` schema [here](https://docs.victoriametrics.com/operator/api.html#vmstorage) and `VMSingle` [here](https://docs.victoriametrics.com/operator/api.html#vmsinglespec).
|
||
1. Enter container running `vmbackupmanager`
|
||
1. Use `vmbackupmanager backup list` to get list of available backups:
|
||
```sh
|
||
$ /vmbackupmanager-prod backup list
|
||
[{"name":"daily/2023-04-07","size_bytes":318837,"size":"311.4ki","created_at":"2023-04-07T16:15:07+00:00"},{"name":"hourly/2023-04-07:11","size_bytes":318837,"size":"311.4ki","created_at":"2023-04-07T16:15:06+00:00"},{"name":"latest","size_bytes":318837,"size":"311.4ki","created_at":"2023-04-07T16:15:04+00:00"},{"name":"monthly/2023-04","size_bytes":318837,"size":"311.4ki","created_at":"2023-04-07T16:15:10+00:00"},{"name":"weekly/2023-14","size_bytes":318837,"size":"311.4ki","created_at":"2023-04-07T16:15:09+00:00"}]
|
||
```
|
||
1. Use `vmbackupmanager restore create` to create restore mark:
|
||
- Use relative path to backup to restore from currently used remote storage:
|
||
```sh
|
||
$ /vmbackupmanager-prod restore create daily/2023-04-07
|
||
```
|
||
- Use full path to backup to restore from any remote storage:
|
||
```sh
|
||
$ /vmbackupmanager-prod restore create azblob://test1/vmbackupmanager/daily/2023-04-07
|
||
```
|
||
1. Restart pod
|
||
|
||
#### Restore cluster into another cluster
|
||
|
||
These steps are assuming that [VictoriaMetrics operator](https://docs.victoriametrics.com/operator/) is used to manage `VMCluster`.
|
||
Clusters here are referred to as `source` and `destination`.
|
||
|
||
1. Create a new cluster with access to *source* cluster `vmbackupmanager` storage and same number of storage nodes.
|
||
Add the following section in order to enable restore on start (operator `VMStorage` schema can be found [here](https://docs.victoriametrics.com/operator/api.html#vmstorage):
|
||
```yaml
|
||
vmbackup:
|
||
restore:
|
||
onStart:
|
||
enabled: "true"
|
||
```
|
||
Note: it is safe to leave this section in the cluster configuration, since it will be ignored if restore mark doesn't exist.
|
||
> Important! Use different `-dst` for *destination* cluster to avoid overwriting backup data of the *source* cluster.
|
||
1. Enter container running `vmbackupmanager` in *source* cluster
|
||
1. Use `vmbackupmanager backup list` to get list of available backups:
|
||
```sh
|
||
$ /vmbackupmanager-prod backup list
|
||
[{"name":"daily/2023-04-07","size_bytes":318837,"size":"311.4ki","created_at":"2023-04-07T16:15:07+00:00"},{"name":"hourly/2023-04-07:11","size_bytes":318837,"size":"311.4ki","created_at":"2023-04-07T16:15:06+00:00"},{"name":"latest","size_bytes":318837,"size":"311.4ki","created_at":"2023-04-07T16:15:04+00:00"},{"name":"monthly/2023-04","size_bytes":318837,"size":"311.4ki","created_at":"2023-04-07T16:15:10+00:00"},{"name":"weekly/2023-14","size_bytes":318837,"size":"311.4ki","created_at":"2023-04-07T16:15:09+00:00"}]
|
||
```
|
||
1. Use `vmbackupmanager restore create` to create restore mark at each pod of the *destination* cluster.
|
||
Each pod in *destination* cluster should be restored from backup of respective pod in *source* cluster.
|
||
For example: `vmstorage-source-0` in *source* cluster should be restored from `vmstorage-destination-0` in *destination* cluster.
|
||
```sh
|
||
$ /vmbackupmanager-prod restore create s3://source_cluster/vmstorage-source-0/daily/2023-04-07
|
||
```
|
||
1. Restart `vmstorage` pods of *destination* cluster. On pod start `vmbackupmanager` will restore data from the specified backup.
|
||
|
||
## Monitoring
|
||
|
||
`vmbackupmanager` exports various metrics in Prometheus exposition format at `http://vmbackupmanager:8300/metrics` page. It is recommended setting up regular scraping of this page
|
||
either via [vmagent](https://docs.victoriametrics.com/vmagent/) or via Prometheus, so the exported metrics could be analyzed later.
|
||
|
||
Use the official [Grafana dashboard](https://grafana.com/grafana/dashboards/17798) for `vmbackupmanager` overview.
|
||
Graphs on this dashboard contain useful hints - hover the `i` icon in the top left corner of each graph in order to read it.
|
||
If you have suggestions for improvements or have found a bug - please open an issue on github or add
|
||
a review to the dashboard.

||
|
||
