Why do you use minio for image serving ? There are much better ways to do so. Nextcloud, Immich, Photoprism and others…

if by better reaction you mean never ever return there, then for sure…

The Omada probably not. But many other tp-link routers support it, especially the low spec ones. I mean, if we are getting to something more performant and feature rich, there are probably much better options, like Turris Omnia, some Microtik stuff and many other.

but what is nice, many tp-link hw can run regular openwrt, which is way better than the thing they provide…

something running openWRT. I for example have a Turris Omnia, which is running their own fork of openwrt. https://www.turris.com/en/omnia/overview/

docker exec nextcloud-mariadb-1 /usr/bin/mariadb-dump --defaults-extra-file=/backup/.mylogin.cnf -u root --single-transaction --quick --all-databases |gzip > /mnt/mysql/backup/nc${NUM}_dump.gz

You are welcome
