[shibly27]

Hi Everybody,

I need advanced level (Spam control, traffic monitoring, Email monitoring etc)
help on Debian Linux 4.0.

How can make a secondary server on which every things of a primary server will be backup automatically..?

I have one debian server where I have configure postfix for email server. Now I want a secondary email server on witch every email will be send automatically.

Is it possible..?

What you ask is possible and pretty easy to achieve. There are numerous walkthroughs available on the net, just google for a bit, that will walk you through this exact setup.

Thanks for quick reply.

I am trying to find out the right one. Like "host standby" or "rsync".


If you have any suggestion then welcome.

I'd suggest using rsync, periodically run by cron.

if you want a hot spare server and backup you need construct a HA system
read some tutorial about HA systems and heartbeat implementatins on linux

if you have two identical server you can build a HA system.
you must set up a heartbeat software on both server. The main server sends signs -it's called heartbeat- to the hot spare server in a certain time periods, if the hot spare server miss 3 heartbeat it mark itself as a main server and takes the jobs of the original main server.
You can set up some synchronization process to synchronize data betwen the servers ,for example rsync
