Hi @JonMikelV, thank you for all that. Turns out the error was caused by not having correct paths specified. I created a new share called “backups” within my unraid box to test and after double checking and setting the correct paths (same as yours above) things worked with Duplicati to save locally.
Hey Duplicati, why use such non-intuitive labels in the description? My friend that set up the server for me said that when you install dockers you leave them to default settings. This is why I was getting confused because I thought /tmp, /backups, and /source were supposed to be set that way. I think a better approach would be to put more accurate descriptions in the docker config labels so dummies like me would understand you actually wanted me to put.
From another thread on unRaid’s site I opened (https://lime-technology.com/forums/topic/69070-how-to-map-a-network-drive/?do=findComment&comment=633451), I learned how to map network drives to my box and that’s from a plugin called: Unassigned Devices.
After installing the plugin, mounting the external NAS drive on my network, and then added a custom path described in the other thread to make Duplicati “see” the network share. I ran a test and it copied the file chunks correctly without error!
Thanks again!
