Fastest way to move Innodb database from one server to another

I understand I can use mysqldump or xtrabackup to move InnoDB from one db to another.

Considering I am okay with server down time, are there better way to move InnoDB database?

I have tried copying all "ib_*" files and seems does not work. Are there anything I've missed?


For anyone wondering, Copying the entire mysql data root (in my case) /var/lib/mysql AFTER shutting down mysqld worked perfectly to migrate data to another system.

Otherwise if you need replication the cluster solutions are more appropriate and faster than DRBD
