I want to backup my current CentOS-7.2 system to another drive. Is it safe to copy the system while it is running? Eg by mount /dev/sdb5 /mnt rsync -HPaxvz /. /mnt/ I've found contradictory advice on the web.
Yes. When we're cloning a system, such as a compute node in a cluster, or rsync upgrading, we rsync -HPavxz /. newmachine:/new/. rsync -HPavxz /boot/. newmachine:/boot//new/.
As long as you're not copying /sys or /proc....
