Home Assistant’s built-in backup system is easy to ignore until the SD card or drive it runs on fails — at which point months of automations and configuration are gone unless a real backup routine was already in place.

A reliable SSD, since backups are only as good as the storage they land on

Moving Home Assistant itself off a consumer SD card and onto a proper SSD dramatically reduces the odds you need that backup in the first place, since SD card corruption is the single most common cause of Home Assistant data loss.

A UPS to prevent corruption during power loss

A surprising share of Home Assistant corruption happens mid-write during a power outage — a basic UPS gives the system time to shut down cleanly instead of losing data at the worst possible moment.
