I have 2 seperate VDS accounts with 2 different providers. The first one is a 1 gbmem based setup with 4 ip addresses, the second is a 2 GB setup with 3 ip address. I have virtualmin/webmin installed on both and running a couple of sites on each . so far so good! Each VDS runs its own dns servers. (When I do a dns check on any site it tells me I have too few name servers etc) I was wondering if it is possible to link the 2 systems so I could run a dns servers to handle ALL the domains, and possibly a backup to each other etc. 2 different physical servers for each DNS. Ns1 and Ns2 etc Ideally I'd like to use each server as backup for the other with all data in case of failure. Neither server is used to anywhere near its potential at the moment. The trouble is I have not found any info relating to this type of idea especially using virtualmin etc. Can a DNS server on VDS1 point to a domain on VDS2 and vica versa. And can I have 2 copies of a virtualsever, one on each VDS and sync them?
Both VDS are running Centos 6.5 and Virtualmin 4.09.gpl GPL
