DR requires money to be spent up front
This is why all my tech guys have laptops, mobiles with modem tethering, remote access from the laptop, with citrix access from any PC to a remote support VMs as back up. In addition we run dual data centres with key infrastructure duplicated and replicated between sites. Multiple ISPs and telcos used for network resilience. Huge UPS with massive generator backup to survive power outages. Every single bit is backed up to tape cross site.
So the only concern is MTR. The fact we have so much data and too few spare servers to put it on, mitigated by the fact we could use VMs. It would be slower than I'd like but we'd not lose any data and would be able to get back every service in time.
