Another use for slaves is readonly scaling. Suppose you have a dozen web servers -- they could need more than one slave to keep up.
Whether you use mysqldump, or stop mysqld and copy files, you must
* Prevent writes during the backup
* Read all the data off disk.
That is, either way, you are interrupting the Slave. And the amount of time is mostly a function of disk I/O, which is pretty much the same for either technique.
