Would be good to have a fall-back solution, is there something similar in dedicated server price in the EU as Hetzner? Or does no on else come close?
Scaleway/Dedibox/Online.net but the hardware is quite a bit older for the price.
There's also Webtropia I have used in the past, also German, without issues.
OVH would be the safest bet but their support is worst than Hetzner.
OVH is comparable, as is digitalocean.
OVH had a datacenter burn down a few years ago, so think about that what you will :)
Imo it makes sense to spread out, and have backups with a different provider than the one your main servers run on. They should all over S3, which is a standardized format for easy syncing of backups
