# Borg Backup to Hetzner Storage Box

For backup I use [Borg](https://borgbackup.readthedocs.io/). I followed the steps described in this community article:

* [Install and Configure BorgBackup](https://community.hetzner.com/tutorials/install-and-configure-borgbackup)

We have two backups in the storage box:

* `/./borgbackup/photoprism`
* `/./borgbackup/nextcloud`

## Photoprism backup

This is what I did for Photoprism

The init script (which is only done once, be careful it will overwrite!):

```sh
# (As root)
export BORG_RSH='ssh -i /root/.ssh/id_ed25519'
export BORG_PASSPHRASE="<I GENERATED A PASSPHRASE>"
borg init --encryption=repokey ssh://u388089@u388089.your-storagebox.de:23/./borgbackup/photoprism
```

It outputs a key which I put in Bitwarden (you need it to decrypt the backup).

To make a manual backup:

```sh
export BORG_RSH='ssh -i /root/.ssh/id_ed25519'
export BORG_PASSPHRASE="<SEE BITWARDEN>"
borg create --stats ssh://u388089@u388089.your-storagebox.de:23/./borgbackup/photoprism::2024_11_24 /home/photoprism/Import/ /home/photoprism/Pictures/
```

The above can be found in Bitwarden, look for "Hetzner Borg Backup Script for Photoprism"

I also created a bash script in `/usr/local/bin/photoprism_backup.sh` (as mentioned in the article).

You can find it here in this repo:

* [photoprism_backup.sh](./scripts/photoprism_backup.sh)

## Nextcloud backup

Ok, this is confusing but Nextcloud uses Borgbackup internally. Go to the [aio interface](http://192.168.1.10:8080/) and you'll notice there are backups to:

```
/root/nextcloudbackup
```

So nextcloud keeps making backups to this directory. Not ideal (TODO: I gotta find a solution for this).

But I can rclone the data:

```sh
rclone sync -v /root/nextcloudbackup/ hetzner:/cloned_borgbackup/nextcloud
```

For this I also created a script and placed it in `/usr/local/bin`

[nextcloud_backup.sh](./scripts/nextcloud_backup.sh)

# Automatic backup

* [cloud_backup.service](./scripts/cloud_backup.service)
* [cloud_backup.timer](./scripts/cloud_backup.timer)

```sh
cp -v cloud_backup.service /etc/systemd/system/
cp -v cloud_backup.timer /etc/systemd/system/
```

```sh
systemctl enable cloud_backup.service
systemctl enable cloud_backup.timer
```
