Automation to reload network storage

I want to store my backups on a network server that is only running during days.

When Homeassistant loses the network share at night it won’t attempt to re-connect the share the next morning unless I manually re-load it.

How do I create an automation event calling the network share re-load process? What is the exact command HA uses?

I’m wondering too. My case is different, with Unraid and HassOS running on Proxmox, I don’t like to delay the start of HassOS by several minute (I need my automations back ASAP), or that I have to reboot HA XX minutes after it started.
