# Duplicati in Docker

[What is Duplicati ?](https://www.duplicati.com/)

A Docker-Compose implementation of Duplicati tailored to work with a Nextcloud instance

## Run

```
* Change the environment variables to your liking
* Specify the path where the data you want to backup is in `docker-compose.yml`
* Launch the container
```

## Nextcloud

There are a few options to tailor this Duplicati instance to backup a Nextcloud data instance

## Restoration point

You can specify the data restoration point into the `docker-compose.yml` if your host system storage is too small. You may link it to a external drive

You will need to tell Duplicati to use the `/restore/` directory when restoring data
