looking to syncronize two servers

[nephish]

Hey there,
i am looking for a way to syncronize two web servers.
both will need to be identical ( this is for redundancy, in case of a computer crash)

both run debian linux with all the same packages.
i need the main one to update any changes to its mysql database to the backup computer.

is there already software out there that will do this?

thanks

You might want to try rsync.

can rsync do a whole system, including mysql ?

i was going to go with unison, but had the same qualms.

thanks

Yeah rsync can do this. You can set it up as a cron job to sync up nightly, every hour, etc.

i looked at the docs after my last post, looks like exactly what i need.
thanks much
