I am trying to backup mysql folder, i used copy (cp) command in linux. the backup folder called mysql_backup.
as you can see below the total size of backup folder is smaller, do you know why is that? i even stop mysql service from running and backed up, still same size. even symantec backup couldn't backup some these folders. does this gives me a problem when retriving example moodle database. or you recommend using something else.
[root@localhost mysql]# du -h
[root@ localhost mysql_backup]# du -h
