mysqldump

-This is a default method.

This script runs only on the sending side and pipes mysqldump output to the mysql client connected to the receiving server. mysqldump needs a username/password pair set in the wsrep_sst_auth variable in order to get the dump. This method requires a READ LOCK (the donor will be read-only during the whole process).

rsync

+This is a default method.

This method uses the rsync utility for snapshots. rsync should be available by default on all modern linux distributions. This is the fastest and recommended method, especially for large datasets since it copies binary data. It requires a READ LOCK during the whole process, as for mysqldump.
