Mirror Servers?

    I use dnsmadeeasy for my dns servers
    I have two servers at godaddy. One is a Virtual DS and another is a Dedicates server.

    I want the ability to mirror the dedicated server on the virtual one, and use dnsmadeeasy's fault tolerance setup as the failsafe.

    Any suggestions or hyperlinks of how to get the server mirrored to the other? My limited research so far takes me to pages that assume I know way more than I do.

    If I knew more, I probably wouldn't be using go daddy, no would I?

    :cool:

    you could use rsync or heartbeat. are you just trying to save the DB or you want complete redundancy?

    complete redundancy.

    Would I run the rsync as a cron? Maybe nightly?

    you could yea, that's usually the easiest way to do it, but that leaves a 1 day window if you server took a dive, plus if you're going for complete redundancy, expect your bandwidth to skyrocket if you have a large site

    In fact no need to mirror data, just mount an amazon s3 bucket using fuse (There is a kernel module) so you wont need any data mirroring at all, because s3 is highly available. Dnsmadeeasy will still work with your failover, this will clear your storage redundancy issues.

    If you want complete failover, you should use ip failover, for this your servers should be on same localnet and can communicate via private ips, the ip failover will be done via arp, so one of your servers go down the other will take over immediately and seemlessly.
