Difference between backup methods: Oracle and MySQL

I was reading that Oracle databases have cold, warm, full and redo backups.

Questions

• How is it possible that MySQL doesn't have as many options?

• I have read that MySQL has cold backups (it puts the DB into a lock mode by itself); are there any other methods?

• How can I implement methods similar to those that Oracle has in MySQL?

Because MySQL is not as mature.

But there are options, such as Percona's (free) hot backup for innodb:

There is also MySQL Enterprise Backup from Oracle, but it is not free.
