Linux / mysql: is it safe to copy mysql db files with cp command from one db to another?
mysqldump
will take 5 hours to run. I have no idea of how much it will take to restore the tables; the database is 300GB in size.
Can't i just shutdown mysql and copy the raw data? Please note that i also want to rebuild (destroy and recreate) the innodb log files. I will use the same version of MySQL and InnoDB (xtradb) is my storage engine.
