# 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. Currently support 
   1. `Amazon S3`
   2. `Azure Storage`
   3. `GCP Cloud Storage` (Use service-account's credential file, [see here](https://cloud.google.com/storage/docs/reference/libraries#linux-or-macos))

## Supported components
* Folder
* Dashboard (contains Alert)
* Datasource
* Alert Channel
* Organization (Needs Basic Authentication (username and password, see [grafana doc](https://grafana.com/docs/grafana/latest/http_api/org/#admin-organizations-api))
	* You need to set `Admin's account and password` in `grafanaSettings.json`, or set the base64 encoded `admin account and password` in ENV `GRAFANA_BASIC_AUTH`. E.g `export GRAFANA_BASIC_AUTH=YWRtaW46YWRtaW4=`
	* Or Sets this ENV of the Grafana server `GF_USERS_ALLOW_ORG_CREATE=true`. see [grafana doc](https://grafana.com/docs/grafana/latest/http_api/org/#create-organization)
* User (Needs Basic Authentication (username and password, see [grafana doc](https://grafana.com/docs/grafana/latest/http_api/org/#admin-organizations-api))
	* You need to set `Admin's account and password` in `grafanaSettings.json`, or set the base64 encoded `admin account and password` in ENV `GRAFANA_BASIC_AUTH`. E.g `export GRAFANA_BASIC_AUTH=YWRtaW46YWRtaW4=`
	* Grafana's api doesn't provide user's password when backing up, so the `default_password (which is in the grafanaSetting.json)` will be used when restoring.

## Requirements
* Bash
* Python 2.7 or Python 3.x
* Access to a Grafana API server.
* A `Token` of an `Admin` role (see `Configuration` section below for more info)

## Configuration
There are three ways to setup the configuration:

1. Use `environment variables` to define the variables for connecting to a Grafana server.
2. Use `hard-coded settings` in `conf/grafanaSettings.json` (this is the default settings file if not specified otherwise).
3. Use `~/.grafana-backup.json` to define variables in json format.

### Example Config
* Check out the [examples](examples) folder for more configuration details

**NOTE** If you use `environment variables`, you need to add the following to your `.bashrc` or execute once before using the tool (please change variables according to your setup):

(`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 
```

To create and obtain a `Token` for your Grafana server, please refer to the [official documentation](https://grafana.com/docs/grafana/latest/http_api/auth/). 

**NOTE** that you need to generate a `Token` with an `Admin` role for the backup to succeed, otherwise you will have potential permission issues.

## Installation
### Virtual environment (optional but recommended)
Create a virtualenv, you could using something like `pyenv` if you'd prefer
```
virtualenv -p $(which python3) venv
source venv/bin/activate
```

### Installation using pypi
```
pip install grafana-backup
```

### Installation using this repo
First clone this repo
```
git clone https://github.com/ysde/grafana-backup-tool.git
cd grafana-backup-tool
```
Installation works best using `pip`
```
pip install .
```

## How to Use
* First perform the **Configuration** and **Installation** sections as described above.
* Use the `grafana-backup save` command to backup all your folders, dashboards, datasources and alert channels to the `_OUTPUT_` subdirectory of the current directory.

***Example:***

```bash
$ grafana-backup save
$ tree _OUTPUT_
_OUTPUT_/
└── 202006272027.tar.gz
```

* Use the `grafana-backup restore <archive_file>` command with a path to a previous backup to restore everything.

**NOTE** this *may* result in data loss, by overwriting data on the server.

***Example:***

```bash
$ grafana-backup restore _OUTPUT_/202006272027.tar.gz
```

## Docker
Replace variables below to use the 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 Grafana host machine.

### Backup

If you decide to use a volume (-v) then you'll need to create the volume first with 1337 uid/gid ownership first, example:
```
mkdir /tmp/backup
sudo chown 1337:1337 /tmp/backup
```

```
docker run --user $(id -u):$(id -g) --rm --name grafana-backup-tool \
           -e GRAFANA_TOKEN={YOUR_GRAFANA_TOKEN} \
           -e GRAFANA_URL={YOUR_GRAFANA_URL} \
           -e GRAFANA_ADMIN_ACCOUNT={YOUR_GRAFANA_ADMIN_ACCOUNT} \
           -e GRAFANA_ADMIN_PASSWORD={YOUR_GRAFANA_ADMIN_PASSWORD} \
           -e VERIFY_SSL={True/False} \
           -v {YOUR_BACKUP_FOLDER_ON_THE_HOST}:/opt/grafana-backup-tool/_OUTPUT_  \
           alpinebased:grafana-backup
