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.
It depends, the running services should answer ... for a mysqld running system:
Delete the -x option above and add
--exclude /proc --exclude /sys --exclude /mnt --exclude /var/lib/mysql
and then
mysqldump --add-drop-table -c --create-options -x -u root -p -A > mysqldump-$(date +%s).sql
for example ...
-- LF
