+I've recently spun up an instance of TrueNAS SCALE after salvaging a couple hard drives from a past computer build and decided I could use additional network storage for various backups such as Proxmox VMs and home directory backups.
+
+<!--more-->
+
+The only app I've needed to install has been Tailscale which has enabled me to access the TrueNAS Web UI from anywhere. I've setup a few datasets and NFS shares to store various backups and the rest of the periodic backups have routinely been working without a hitch. Since my homelab is becoming more of a vital piece of infrastructure for my daily needs, I wanted to ensure that these datasets had [Cloud Sync Tasks](https://www.truenas.com/docs/scale/scaletutorials/dataprotection/cloudsynctasks/) setup for offsite backups. These encrypted backups are mostly being stored in places such as Google Drive and other blob storage providers.
+
+More recently, to reduce cloud costs, I've setup some a small node at another physical location and installed both Tailscale and [sftpgo](https://github.com/drakkan/sftpgo) on it to facilitate offsite backups. After setting up the infrastructure and adding a Cloud Sync Task in TrueNAS SCALE to replicate these backups offsite to sftpgo, I noticed that Tailscale's Magic DNS was not working, nor was the Tailscale IPv4 address.
+
+After reading the [Tailscale docs](https://tailscale.com/kb/1483/truenas#route-non-tailnet-traffic-through-truenas) , it became clear that the **Userspace** box had to be unchecked in the Tailscale app settings. This is because the Tailscale app is running within a docker container on the TrueNAS SCALE VM. After unchecking the **Userspace** box, I was able to verify that the Backup Credentials created for sftpgo worked when specifying the host as a Tailscale IPv4 address. This was probably good enough since the IP won't change unless the node is re-registered, but I figured setting up MagicDNS would make the setup more portable.
+
+To get MagicDNS working, I went to Network > Global Configuration and set "Nameserver 1" to **100.100.100.100**. After this, I was able to specify the FQDN in the Backup Credentials and the Cloud Sync Tasks started.
