Danp yes, I'm getting this error on the settings > remotes page.

As you can imagine, I'm confused why NFS works on the main SR page, but not the settings > remotes page

EDIT: never mind, discovered that I have to put the full share path, not just the share name.

Example:

\\10.69.50.31:Port:/mnt/user/UnraidBackup/XCPNGBackups

Using XCPNG and XO from sources.
I'm migrating my home lab VMs from Unraid to XCP-NG. I'd like to still backup my VMs from XCP-NG to Unraid

I've set up a NFS share on Unraid.

When I try to create an NFS share to use in my Storage (SR) pool, I can connect to it no problem.

However when I try to create a backup job to back to this share, XCP-NG states no NFS remotes available.

I go through the process and create a NFS remote on the settings page.
I get this error when saving
"mount.nfs: access denied by server while mounting 10.69.50.31:/UnraidBackup/XCPNGBackups"
I have made sure NFS share is published on the unraid side and it requires no auth (internal only access)

Suggestions?
