Disaster recovery / backups are never important until ya need them (been there, done that, lost the data).
I've got a full copy of the WSPRnet dataset also, in multiple locations. Not that I really need to, but, its nice not having to re-download those big files.
I've got data center infrastructure on Azure and AWS in multiple zones also. It's costly to have and maintain, but, it's there when the lights go out in a zone.
