# Setup & Configuration

We need to install the service through Portainer and configure any necessary settings.

# Preparation

There are some things we need to do in preparation to install this service.

## Volumes

<details id="bkmrk-media-folders-radarr"><summary>Persistent Data</summary>

This is where the service will store its own application data and ensures we can quickly update the service image.

<p class="callout warning">Ensure your user has permissions to access the folder.</p>

</details><details id="bkmrk-media-folders-this-s"><summary>Source Folders</summary>

This service will need access to the folders where you store the files you are backing up.

<p class="callout warning">Ensure your user has permissions to access the folder.</p>

</details>## Environment

<details id="bkmrk-tz-this-is-the-curre"><summary>TZ</summary>

This is the current time zone formatted using the [tz database.](https://en.wikipedia.org/wiki/List_of_tz_database_time_zones)

<p class="callout info">*For example:* America/Vancouver</p>

</details><details id="bkmrk-gid-%C2%A0"><summary>PUID</summary>

This is the numeric ID of the user account on Debian. If you are unsure, open a terminal and run:

```bash
id -u
```

</details><details id="bkmrk-pgid-this-is-the-num"><summary>PGID</summary>

This is the numeric ID of the user account's group on Debian. If you are unsure, open a terminal and run:

```bash
id -g
```

</details>### Passwords

<p class="callout danger">Keep these securely stored in a password manager, such as [VaultWarden](https://hub.subspace.services/books/vaultwarden "VaultWarden").</p>

<details id="bkmrk-db_root_pass-this-is"><summary>SETTINGS\_ENCRYPTION\_KEY</summary>

This is the secure phrase that will be used for encrypting your files and the service database.

<p class="callout warning">It is important to use secure, randomly generated password.</p>

You can use a random alphanumeric string from a password manager, or open the terminal and run the command:

```
tr -dc 'A-Za-z0-9!"#$%&'\''()*+,-./:;<=>?@[\]^_`{|}~' </dev/urandom | head -c 32; echo
```

This pulls a random string from the '[urandom](https://en.wikipedia.org/wiki//dev/random)' device, removes unwanted characters and trim it to an appropriate length.

</details><details id="bkmrk-duplicati__webservic"><summary>DUPLICATI\_\_WEBSERVICE\_PASSWORD</summary>

This is the password for logging into the web interface.

<p class="callout warning">It is important to use secure passphrase that is easy-to-remember.</p>

</details>
