2 DA Servers Question - Backup to each other / Shared DNS

[flyride]

Quick question I've spent an hour and I can't find an answer to:

The setup (both at separate physical locations):
2 servers, both on DA:
ns1.domain.com ---> server 1
ns2.domain.com ---> server 2

The variables:
- DNS would be linked through DA's multi-server setup
- There are no actual resellers
- Each server would have a reseller account created with its own unique name (ie Reseller accounts named: server1 & server2), all domains within these reseller accounts
- Each server will do a DA backup daily to each other

My question is:
1.) If one server (lets say server1) goes down, could I effectively just import my reseller backup of server1 onto server2 (adding a 2nd reseller) and have the sites online again immediately?

2.) When server1 comes back up, can I just delete the reseller1 user/sites off of server2, and be back up and running on both individual servers?

Thanks in advance!

Multiserver is for dns only. If you want something automated there are many clustering programs on the internet.

Under your limited scenario you should be able to import your reseller backup to your second server, but only if it doesn't have any sites of its own or if you're careful to not overwrite usernames, etc. However you may restore the original IP#s and you may have to change all your DNS manually.

Another issue of course is that if you have any MySQL databases, you may be reverting to an old database, and lose a lot of data.

I wouldn't recommend this method of implementing high-availability.

hmmmm, I hadn't considered the mysql's db's being outdated when switching back to original server. The usernames wouldn't be an issue as there isn't really much going on on the other server.

Ok, well thanks for the info guys. I will investigate some other redundancy avenues. If DRDB / heartbeat wasn't such a pain to setup I would go that route. Guess there isn't really an easy answer.
