Re: Data Redundancy



I have a dedicated server at the moment (which is the one i want mirrored), i have considered the solution below before, but does the dns "load balance" to a server when it is down? i've been told that it doesn't, but i haven't put it into practice yet.  What i really need is a service to check whether the main server is available, and if its not, switch to the secondary.  The solution below does take care of the data redundancy problem though.

Cheers

What I do is purchase ( if money is an option ) a near identical server, then create your own scripts just to copy changed data, using the tar program. For Mysql I use Mysql dump. Do not host any sites using postgreSQL so no advice in that area. Cron will only have to be copied once, same with most of your config files. DNS obviously is not an issue.

 

I have my setup working, mirroring data daily.

 

Have you thought about renting a dedicated server for the role you are after?

Yes i need to mirror all functions, programs, crons, databases etc to do with a web server.  I have been looking this up and it seems, as roberto said in an earlier post, its is going to be an expensive exercise.  I really need a cheap option at the moment if there is such a thing.

Hi All,
 
I have a server that i need to mirror elsewhere for data redundancy
purposes.  What is the best way to have this done?  The sites on my box
are MySQL and PostgreSQL driven so those need to be on both machines as
well.  Ideally id like to have a main server and in any event that the
main server went down, switch to the other server.
Any info greatly appreciated
    
 
Do you mean that you need to mirror the MySQL & PostgreSQL
databases, or some non-database files, or both?
