Re: Clone ES4 machine

I, too, am looking for a way to clone. What I want to do is have 2 disks in a computer and make changes to the first disk. If the changes break things, I can swap the disks, re-clone the one I just made the master to the now broken disk, and make adjustments to the changes I just made.

I do this on SOlaris with ufsdump and ufsrestore script that can dupe a disk in 10 minutes.

I don't want to reinvent the wheel, so I am looking for someone who has already done this with system commands and a script.

Unfortunately, I work in a place where I cannot import software from the Internet and install it. I have only inherent OS functions to use.

I am looking to 'clone' one of our ES4 production machines to make an
exact copy as a development box. Does linux have a built in method for
this or can someone point me in the right direction for a method for
this. TIA.

Rsync is a simple way to copy a complete system. The procedure goes
something like this:

+ Boot a rescue image that contains a recent rsync binary
+ Partition your disk(s)
+ Create the filesystems and mount them in a directory structure that
has sufficient filesystem space (or optionally mimics the original
system)
+ Rsync the original system onto your new filesystem structure

The tools you would use are resp. fdisk, mkfs (or mfks.ext3), mount, mkdir
and rsync.

I didn't mention that you need network as well, although the rescue image
could have done that for you using dhcp.
