+To back up [my NAS](nas_2018.html#06_2022) I was shopping around for different cloud storage providers that I could use with [BorgBackup](https://www.borgbackup.org/).
9

10
+Here are some yearly prices, calculated for a storage requirement of ~22TB (22.000GB).

85
+
86
+As you can tell, most providers I looked at are actually pretty expensive.
87
+One reason for this are their guarantees against data-loss.
88
+
89
+One of the rows in the table above is not like the others, and that is the [Hetzner Storage Box](https://www.hetzner.com/storage/storage-box).
90
+These do not provide a dynamically growing storage, like the others.
91
+Instead you get a fixed amount of memory, depending on the amount of money you pay.
92
+The largest available size is 20TB, which is less than the 22TB I calculated with.
93
+But in reality I only need ~16TB currently for backups.
94
+
95
+Because this is only used as an offsite backup for me, I decided to go with it for it's far lower price, because I can live with the possibility of losing data when their [DC burns down](https://en.wikipedia.org/wiki/OVHcloud#Incidents) or something 🚒 🧑‍🚒
96
+
97
+Ordering a new storage box instance is straight-forward.
98
+You get a username, DNS name and auto-generated password in the Hetzner Web UI.
99
+In there you can also enable different access methods; we need SSH for Borg.
100
+
101
+Setting up [SSH authentication](https://docs.hetzner.com/robot/storage-box/backup-space-ssh-keys) and [using Borg](https://community.hetzner.com/tutorials/install-and-configure-borgbackup) are described in the [Hetzner docs](https://docs.hetzner.com/robot/storage-box/).
102
+
103
+The workflow is a bit strange, I have to admit.
104
+While you can use Borg or rsync over SSH with the storage box, interactive logins are not possible and you can also not use `ssh-copy-id`.
105
+Instead, commands need to be executed via sftp.
106
+These are the steps I had to do to enable public-key authentication and initialize a borg repo.
107
+
108
+<pre class="sh_sh">
109
+cat .ssh/KEY.pub >> storagebox
110
+echo -e "mkdir .ssh \n chmod 700 .ssh \n put storagebox .ssh/authorized_keys \n chmod 600 .ssh/authorized_keys" | sftp USER@USER.your-storagebox.de
111
+rm storagebox
112
+echo -e "mkdir backups \n mkdir backups/NAME" | sftp USER@USER.your-storagebox.de
113
+BORG_RSH='ssh -i /home/USER/.ssh/KEY' borg init --encryption=repokey ssh://USER@USER.your-storagebox.de:23/./backups/NAME
114
+BORG_RSH='ssh -i /home/USER/.ssh/KEY' borg key export ssh://USER@USER.your-storagebox.de:23/./backups/NAME keyfile
115
+mv keyfile SOMEWHERE_SAFE
116
+</pre>
117
+
118
+Then I simply adapted my [existing backup scripts](2022_05_16_borg_backup.html) to add a BORG_RSH export.
119
+
120
+<pre class="sh_sh">
121
+#!/bin/sh
122
+
123
+export BORG_REPO=ssh://USER@USER.your-storagebox.de:23/./backups/NAME
124
+export BORG_PASSPHRASE='PASSWORD'
125
+export BORG_RSH='ssh -i /home/USER/.ssh/KEY'
126
+
127
+export BACKUP_PATH=/PATH_TO_BACKUP
128
+export BACKUP_EXCLUDES="      \
129
+    --exclude=/EXCLUDED_PATHS \
130
+"
131
+
132
+backup-borg
133
+
134
+backup_exit=$?
135
+exit ${backup_exit}
136
+</pre>
