# Backups
|
||
|
|
|
||
|
|
We use [Restic](https://restic.readthedocs.io/en/stable/) to create backups and push them to two repositories.
|
||
|
|
Check `./modules/backups.nix` and `./hosts/nachtigall/backups.nix` for working examples.

### Hetzner Storagebox
|
||
|
|
|
||
|
|
- Uses SFTP for transfer of backups
|
||
|
|
|
||
|
|
Adding a new host SSH public key to the storagebox:
|
||
|
|
|
||
|
|
First, [SSH to nachtigall](./administrative-access.md#ssh-access), then become root and add the new SSH public key
|
||
|
|
|
||
|
|
```
|
||
|
|
sudo -i
|
||
|
|
echo '<ssh-public-key>' | ssh -p23 u377325@u377325.your-storagebox.de install-ssh-key
|
||
|
|
```
|
||
|
|
|

### Garage S3 buckets
|
||
|
|
|
||
|
|
- Uses S3 for transfer of backups
|
||
|
|
- One bucket per host, e.g. `nachtigall-backups`, `metronom-backups`
|
||
|
|
|
||
|
|
To start transfering backups from a new hosts, this is how to create a new bucket:
|
||
|
|
|
||
|
|
First, [SSH to trinkgenossin](./administrative-access.md#ssh-access), then use the `garage` CLI to create a new key and bucket:
|
||
|
|
|
||
|
|
```
|
||
|
|
export GARAGE_RPC_SECRET=<secret-in-keepass>
|
||
|
|
|
||
|
|
garage bucket create <hostname>-backups
|
||
|
|
garage key create <hostname>-backups-key
|
||
|
|
garage bucket allow <hostname>-backups --read --write --key <hostname>-backups-key
|
||
|
|
```
