Already got ssd as a nfs share in my openwrt-based router before that I did have it set up on the rpi. I did want to do offsite backup into that disk originally but I’ve got “only” ~100Mb/s up/down speed here so I didn’t want to risk slow-downs etc (but now that you remind me, borgbackup should be rather light on traffic!).
NEMS being a whole OS is a pitty, I like the possibility to have multiple different services there.But you are absolutely right I could have a offsite resource monitoring for my Hetzner setup with these, thanks!
