Data Redundancy

[Will Parkinson <wil@businessleader.com.au>]

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

Cheers

Will
