Wondering if there's any way to backing up with TFTP without using its DHCP server. I want to keep my own router configuration using DHCP. The Folding@home box is actually a Server 2008 workstation with Hyper-V enabled. It is running some other VMs, but mostly it is dedicated to VM doing SMP folding.. it loads up the diskless iso and just goes. I'd like to backing up to another machine just in case that one goes down.
At one point I had a setup where I rolled my own
DHCP+NAT in a separate subnet for a diskless folding VM. I used Windows 2000's built-in TFTP server (apparently after 2000 they removed the server component) and Microsoft's DHCP and DNS servers. The key to doing that is option 066, "Boot Server Host Name". The description for it is "TFTP boot server name". It basically tells the DHCP server to return that extra information for DHCP clients so it can talk TFTP to that server. So in theory, if your DHCP server in the router (consumer grade routers won't cut it, probably should be a full-blown Linux/Windows router) support 066, you should be able to disable the DHCP portion of Tftp32 and add a bit more configuration to your existing DHCP. If your router can't do that, then there are now 2 ways:
1. Use Windows file sharing to the VM and roll your own periodic backups on the work folder, most likely with your own scripts.
2. Use a subnet with your own DHCP+NAT+TFTP similar to my setup. This will be most beneficial if you have multiple VMs. This also allows you to pick the most appropriate router and TFTP server software for you.
The Model M is not for the faint of heart. You either like them or hate them.
