I haven't tried running Amanda on a host with two IP numbers on the same subnet, but another possibility is that the routing configuration on the backup server host have been changed somewhat during the loss and re-creation of the "eth0" config file. Given the right sort of change, that might result in that the kernel is now choosing a different "route" for communicating with the client hosts, which in turn might lead to it to assign a different source IP to the outgoing packets. If that's the cause of your situatino, the "ip route get" command might give you some hints as to why that's happening. (I'm assuming you are running Linux on that host.) See e.g. http://linux-ip.net/html/tools-ip-route.html#tools-ip-route-get for more info.
