is it possible to have the ability to monitor the attix5 backup application, providing a warning if it fails? Thanks

You could use our API and create a plugin, there are a few examples here including a Vembu StoreGrid plugin.

Hope this helps.

Unfortunately Attix 5 does not expose any public API, which complicates things a bit.

Does Attix 5 writes to event log? If so, you can setup an event log filter that will notify you if something went wrong.
