# Grafana Dashboard Backup Tool

A Python-based application to backup Grafana settings via [Grafana API](http://docs.grafana.org/http_api/overview/).


## Requirements
* bash
* python 2.7, python 3.x with `requests` library installed (`pip install requests` ?)
* access to a Grafana 3.0 API server

## Configuration

`grafana-backup-tool` uses environment variables to define the connection to a Grafana server, or alternatively hard-coded settings in `src/grafanaSettings.py`.
You need to add the following to your `.bashrc` or execute once before using the tool:
```bash
# do not use a trailing slash!
export GRAFANA_URL=http://some.host.org:3000
export GRAFANA_TOKEN=eyJrIjoidUhaU2ZQQndrWFN3RRVkUnVfrT56a1JoaG9KWFFObEgiLCJuIjoiYWRtaW4iLCJpZCI6MX0=
```

There is [official documentation](http://docs.grafana.org/http_api/auth/) how to obtain the `TOKEN` for your installation.

## How to Use
* First perform **Configuration** as described above.
* Use `backup_grafana.sh` to backup all your dashboards, datasources and folders 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.
