[UNCLASSIFIED]RE: [clug] Best way to backup an entire harddisk

Hi Chris,

I keep nigh-identical development and production servers.

You should be able to push your Tomcat stack out to the production
system using ssh/rsync. You can even use mod_jk to switch between
Tomcat instances transparently.

I don't try doing the whole hard disk as our internal/external
environments are different. Having a dev server locked down
as tight as prod would be a nuisance (i.e. no Samba access,
no remote database connects).

SuSE will let you build a build "recipe" that will streamline the
deployment of base systems with the same config.

Subject: [clug] Best way to backup an entire harddisk

Hi,

I have just finished installing a tomcat server on apache2, I would like to deploy this system to a different machine in a remote location. What is the best way to do this?

I have tried G4L (Ghost for Linux), Mindo, etc. Given that the current machine doesn't have a burner, if not storing the new image across the network, does that mean I have to create a spare partition or mount an external harddrive to backup the system?

With the former approach, say I have /dev/hda1 as / , /dev/hda2 as / home, Do I need also to create a /dev/hda3, and put the creating image in there? Then burner them, but how do I restore them to a new machine?

With the latter approach, I could use dd to copy the entire disk bit by bit, say if the harddisk is 80 GB, do I need another one at least as big as the first one?

Or is there other way to do this?

Thanks

Chris
