What about the MySQL Administration backup routine, which can be scheduled for a convenient time? No-one has mentioned this one. We use it but perhaps there is something I should know...?

In addition, from the slave server, you might look at running the new mysql-parallel-dump tool that Baron Schwartz has developed. It essentially does a dump with a thread running (by default) for each CPU core you have. A dual core box will run two threads and dump roughly twice as fast as a normal mysqldump. In addition, it compresses the output making it much more compact. He has renamed the toolkit to Maatkit and it is available at http://maatkit.sourceforge.net/. Also, you might look into using an LVM snapshot to run the copy from. That way it doesn't interfere with your operations as much. I do that for some of our production slave servers myself.
