 The nginx configuration was pretty straight forward, just copying what was provided by the documentation.  
 There is one option "HSTS" that will add the domain of the site to a list that modern browsers will check to force the site to be https. I already added a redirect to https and I'm pretty confident that I will not be accessing the server through http so I don't think this is necessary. I'm not sure how it would affect the other subdomains.
 
+### External drive
+Digital ocean is great, the constant uptime and the speed makes it well worth the extra cost.  
+The biggest downside is the limited storage.
+
+To solve this I have created a very simple local SFTP server on a Raspberry Pi.  
+This allows me to keep all of my large files that don't need rapid access on a terabyte hardrive at home (that can also be accessed on the local network), and connect to it through Nextcloud so I have access to it anywhere.  
+The steps to build are as follows:
+- Install [Armbian](https://www.armbian.com/rpi4b/) on the Pi.
+- In the setup select bash as it will boot up faster when SSHing.
+- There is a relatively slow and unnecessary dynamic banner when connecting. To disable go to `/etc/default/armbian-motd` and change the first line to:
+```sh
+MOTD_DISABLE="config header tips updates sysinfo"
+```
+- Automatically mount the SSD
+  - Find out the id of the SSD partition with `lsblk` and `blkid`
+  - Update the `/etc/fstab` file
+```
+UUID=<ID> /mnt/drive vfat noatime,x-systemd.automount 0 2
+```
+- Add ufw firewall rules
+
+#### Future tasks with External drive
+- [ ] Send a request to automatically update IP address on VPS
+- [ ] Automatic backups of local and Nextcloud files

 Now this one was a nightmare, but would have been a dealbreaker without it.  
 I was following all the advice and I just couldn't get it to work with my set up.
