If it’s just a co-located server, the hosting company would have no responsibility or access to do backups, they’re just there to provide network connectivity, UPS, physical security, and to swap failed RAID drives or do other hardware maintenance as requested by the client.
The real question here is that if the drives were blank, what exactly was being hosted there? There’s no reason to co-locate a server with blank drives, it wouldn’t do anything.
Thanks for the education. Makes a little more sense now. AND more questions.
