Backup external hdd Linux


Sorry if this is a stupid question, i’m new to duplacati.

I have duplacati runnuing via portainer in openmediavault and I want to backup one of my shared folders to googledrive but I cant seem to see my folder. Which is on an external USB hard drive. Am i missing something obvious, can this even be done?

I’m running: Duplicati -
OMV: 5.5.11-1 (Usul)


Containers won’t have access to the host filesystem unless you specifically grant it through mappings. I have some experience on this with Docker but I’m not familiar with OMV.

Can you check the container configuration and look around for settings related to volume mappings?

Here’s my current volume mappings:

Host/volume Path in container
/srv/dev-disk-by-label-LOCAL/Pictures/config /config
/srv/dev-disk-by-label-LOCAL/Pictures/dummy /backups
/srv/dev-disk-by-label-LOCAL/Pictures/dummy /source
/srv/dev-disk-by-label-LOCAL/Pictures /Pictures


Ok, do you see /Pictures in your container? If it shows up but has no contents, it may be a permission issue. The container needs to run with UID/GID that has access to the underlying files.
