A locked mysql database works faster.
If you use mysqldump to backup, it's locked by default. That can be
changed with arguments though.

If you use something like a PHP loop to export every table on it's own,
the risk is that one table is written to while the PHP script is
exporting another, thus leaving you with un-synced data.
That might not be a risk, depending on what your database structure is...
