# Grafana Backup Tool

A Python-based application to backup Grafana settings using the [Grafana API](https://grafana.com/docs/grafana/latest/http_api/).

The aim of this tool is to:
1. Easily backup and restore Grafana.
2. Have versioned backups`(date and time in file name)` for restoring and saving to cloud storage providers like `Amazon S3` or `Azure Storage`.

## Supported components
* Folder
* Dashboard (contains Alert)
* Datasource
* Alert Channel

## Requirements
* Bash
* Python 2.7 or Python 3.x with `requests` (https://requests.readthedocs.io/en/master/) library installed (`pip install requests`)
* Access to a Grafana API server.

## Configuration
There are two ways to setup the configuration for the script:
* Use `environment variables` to define the variables for connecting to a Grafana server.
* Use `hard-coded settings` in `src/conf/grafanaSettings.py` (this is the default settings file if not specified otherwise).

- If you use `environment variables`, you need to add the following to your `.bashrc` or execute once before using the tool:

(`GRAFANA_HEADERS` is optional, use it if necessary. please see [#45](https://github.com/ysde/grafana-backup-tool/issues/45))
```bash
# Do not use a trailing slash on GRAFANA_URL
export GRAFANA_URL=http://some.host.org:3000
export GRAFANA_TOKEN=eyJrIjoidUhaU2ZQQndrWFN3RRVkUnVfrT56a1JoaG9KWFFObEgiLCJuIjoiYWRtaW4iLCJpZCI6MX0=
# GRAFANA_HEADERS is optional
export GRAFANA_HEADERS=Host:some.host.org 
```

There is an [official documentation](https://grafana.com/docs/grafana/latest/http_api/auth/) on how to create and obtain the `TOKEN` for your Grafana server.

- If you use the hard-coded settings in `src/conf/` directory, but you have multiple instances of Grafana servers in your network that you would like to backup,, you can create multiple settings files in the `src/conf/` directory (with the name of the server for example) and use them when running `backup_grafana.sh` and `restore_grafana.sh`. 

## How to Use
* First perform **Configuration** as described above.
* Use `backup_grafana.sh` to backup all your folders, dashboards, datasources and alert channels to the `_OUTPUT_` subdirectory of the current directory.
 For example:
```bash
$ ./backup_grafana.sh
$ tree _OUTPUT_
_OUTPUT_/
└── 2019-05-13T08-48-03.tar.gz
```
* Use `restore_grafana.sh` with a path to a previous backup to restore everything. **NOTE** this *may* result in data loss, by overwriting data on the server.

## Docker
Replace variables below to use docker version of this tool
* `{YOUR_GRAFANA_TOKEN}`: Your grafana site token.
* `{YOUR_GRAFANA_URL}`: Your grafana site url.
* `{YOUR_BACKUP_FOLDER_ON_THE_HOST}`: The backup folder on the host machine.

### Backup

```
docker run --rm --name grafana-backup-tool \
   -e GRAFANA_TOKEN={YOUR_GRAFANA_TOKEN} \
   -e GRAFANA_URL={YOUR_GRAFANA_URL} \
   -v {YOUR_BACKUP_FOLDER_ON_THE_HOST}:/opt/grafana-backup-tool/_OUTPUT_  \
   ysde/docker-grafana-backup-tool
```

***example:***

```
docker run --rm --name grafana-backup-tool \
   -e GRAFANA_TOKEN=eyJrIjoiU2Y4eTByUGExOEZhajNYaTVyZTBuNlJOc3NaYkJiY3oiLCJuIjoiYWRtaW4iLCJpZCI6MX0= \
   -e GRAFANA_URL=http://localhost:3000 \
   -v /tmp/backup/:/opt/grafana-backup-tool/_OUTPUT_  \
   ysde/docker-grafana-backup-tool
```


### Restore

```
docker run --rm --name grafana-backup-tool \
   -e GRAFANA_TOKEN={YOUR_GRAFANA_TOKEN} \
   -e GRAFANA_URL={YOUR_GRAFANA_URL} \
   -v {YOUR_BACKUP_FOLDER_ON_THE_HOST}:/opt/grafana-backup-tool/_OUTPUT_  \
   ysde/docker-grafana-backup-tool restore _OUTPUT_/{THE_ARCHIVED_FILE}
```

***example:***

```
docker run --rm --name grafana-backup-tool \
   -e GRAFANA_TOKEN=eyJrIjoiU2Y4eTByUGExOEZhajNYaTVyZTBuNlJOc3NaYkJiY3oiLCJuIjoiYWRtaW4iLCJpZCI6MX0= \
   -e GRAFANA_URL=http://localhost:3000 \
   -v /tmp/backup/:/opt/grafana-backup-tool/_OUTPUT_  \
   ysde/docker-grafana-backup-tool restore _OUTPUT_/2019-09-09T10-00-00.tar.gz
```


## Notes
* Please have a look at the two bash scripts in the root directory if you need to customize something.
