@Tomahawk, here’s a POC of an addon that does some of what you want. Every time you start the addon, it’ll automatically copy all backups to /dev/sda1, then apply the retention policy, then stop. You can automatically start the addon with hassio.addon_start service via an automation.
To install it, create a folder named \\hassio.local\addons\copy_backups_to_sda1 then place all 3 of these files in that folder. Refresh your addons and install it.
I don’t plan on continuing development on this. If you decide to improve on it, let me know how things progress.
