Acronis Backup: PXE Boot Fails with "Failed to download bootwiz.cfg"

Thread needs solution

Hi 

I am having exactly the problem, described in this article: https://kb.acronis.com/content/47149

Although there is a solution to this problem in the KB, this will not work in our kind of setup.

 

Facts of our setup

  • The Client I am booting from is located in a branch office location
  • A routed VPN tunnel to the server, running Acronis Services and PXE is present
  • The server has no DHCP service running
  • no firewalling between the two VPN endpoints -> all ports are open
  • DHCP Relay at the branch location is not possible, only dhcp options like 66/67 can be configured
  • There is a local DHCP Server (Firewall) at every branch office

I am trying to to get this to work, with the right DHCP options configured. I already user the 66 and 67 options for PXE boot and they are obviously correct. Otherwise the "Starting Acronis Loader..."  would not appear on the client.

Is there any other option I can configure to get this to work? Remember, I can not use a DHCP relay.

has anyone done this kind of setup before?

 

thanks a lot,

lauro

I believe the PXE service only works if the subnet is exactly the same.  Have you tried using unicast instead of multicast as well - might have less trouble with that.  Other than that, what's your VPN connection speed - I've seen local networks take 10 minutes to fully pxe boot in some instances - could be longer across VPN so is it actually failing, or just REALLY slow and not being given enough time to load the image into memory across the VPN connection?

Perhaps not what you're looking for, but could you copy your image to the local network on the remote end and have someone boot up the offline rescue media instead?  They can then use the "stand-a-lone" option via bootable USB drive or DVD/CD and navigate to share where the .tib image is located (this should tecnically work even if you left the image in the default location, but I imagine it would be much faster doing it "locally'" with a copy of the image than going across your VPN connection.  Even though it's not  completely automated, if you don't have to crank these out religiously, it could be a decent work-a-round to keep things going.
