Is it possible to make the /backup folder available to the Unraid host HA is running under?

I’m running the Samba Backup add-on and I currently have it set to fire off a full backup every night at midnight. I also have an automation in NodeRED that fires off the same backup every day at noon.

The destination folder for the Samba Backup is a share on the Unraid server under which HA runs as a VM.

The Problem
Samba Backup only seems to be able to do a single configured scheduled backup. As I’m using Vaultwarden inside of HA as an add-on to manage passwords, I want Vaultwarden backed up more frequently (every 2 hours.)

I can achieve this with an automation, but since Samba Backup is configured for a full backup, I don’t need that to be happening every 2 hours, yet I still need to be able to transfer the Vaultwarden backup to Amazon S3 automatically like Samba Backup does. In order to do this, I need Unraid to be able to read the /backup folder inside of HA so I can use another backup utility to send the contents of the backup folder to S3.

I have a share in Unraid called /systemBackups which is where everything I’m backing up goes before it’s transferred to S3 unless a particular backup service itself initiates the transfer.

Question: How do I mount the /backup folder in HA which is running as a VM in Unraid to the Unraid share structure (/mnt/user/systemBackups/vaultwarden) given the fact that mount point is running under unraid’s VM?

Do I need to create a mount that waits for a while before trying to connect? Thanks for the help if you know.

Have you tried the method used for media? Setting it up as a media folder may work.
