mirror hdd to ssd

ikoro · 11-09-2017, 04:07 AM

Hi to all,

I'm newbie in Linux and in the forum also..

I would like to ask about how to clone an HDD to SSD. The HDD has Linux 6.6 and is a server with freePBX and Asterisk. My point is to have a whole backup in case of disaster and i have already bought a new SSD 128gb.

Thanx in advance

hi first there is NO linux operation system called "6.6"

there is redhat Enterprise Linux 6 ( 6.9 is the last minor version )
-- rhel 6.6 is from 2014 - FIVE years ago )

or besides redhat there are the rebuilds
CentOS
ScientificLinux
Oracle unbreakable Linux

for backup
use the dd command ,or any of the backup tools installed

and UPGRADE ASAP
if this is a unlicensed rhel6.6 install you are missing 5 YEARS!!!! of security updates

thanks for the fast reply John, the freePBX running CentOS 6.6,yes it's an old version.
With a fast search before post in the forum I realize that the best tool is dd as you say.I don't know if clonezilla is also usefull and good as dd.

keep up the good work

If your HDD is larger than the SSD you are cloning to, DD will not work. You could try rsync instead. But either way, depending on how your fstab is setup you may have to change some UUID's or whatever your disks referenced by to get the system to boot properly
