Currently there is an issue happening on the production environment and not happening in dev. so I would like to recreate it in dev by creating a image of prod and restore it in dev. the hardware are the same as well as the RAID. My question is
a. what the best tool to use to do that?
b. when creating the image, does it require any downtime?
c. I presume that i need to do some configuration changes once the restore is done?
d. after the restore, would the logic/physical mount be eased?
Plus I am new to Ubuntu, have tried tar way to do. it seems that it caused lots of issues. I have gave up on that due to time limitation.
Thank you so much.
