Knowing that my last automatic backup failed is useful information. [One would argue that this condition should also trigger a Notification to be more prominate) And knowing when the last good backup was is also useful information. What is lacking is a link from here to the last good backup. But I could understand that if the following screen was better
I never trust a single backup method. Also, I can’t use the new Nabu cloud backup because my backups are about 7Gb. Too large for the Nabu cloud.
I use Samba Backup to a shared volume on my NAS. You don’t need a full-blown NAS; a Raspberry Pi (not the one running Home Assistant) with a 2Tb USB SSD drive. I also copy my config folder to my NAS every night. (When I screw things up it’s usually a YAML configuration file).
You can also use the Google Backup add-on. I’ve never used it, but it is pretty popular.
