Same. I lost a lot of photos this way. I've recently moved over to Immich + Borg backup with a 3-2-1 backup between a local synology NAS and BorgBase. Painful lesson, but at least now I feel much more confident. I've even built some end-to-end monitoring with Grafana.
Thanks... hence, 3-2-1 backups with offsite :) appreciate it though. Will definitely be rolling my own NAS in the future, I just needed something easy at the time.
