One note to add - if you are using a MySQL version prior to 4.1, mysqldump by default passes all data to memory when preparing the backup. If you use --opt it will prevent this - and perhaps allow more efficient backup of large databases without crunching your server's ram.</p> <p>If you really want to jam your ram and have version 4.1 or better - you need to use --skip-opt as it is on by default now to improve large database backups.</p> Good point on large tables.

You need the tables locked when you copy them.

If you’re stopping mysql every time you backup that shouldn’t be a problem though.
