[H-GEN] Cloning Linux System

[Kelvin Heng]

Hi guys,
I have a question, hopefully there is a solution for it.

I need to clone a Redhat Linux (7.2) server to a secondary location (e.g. 
Another Server or USB HDD). But I have some restriction, I am not able to 
have any downtime for the server and will be required to carry out this task 
while the system is operational.

Please advise if you know of any method. Thanks in advance.

Any comments or suggestions will be greatly appreciated.

Regard,
Kelvin Heng
