@mgorny honestly I’ll take #Galera multi-master backup over “hand-crafted” multi-master replication any day. That said, backups were slightly more difficult to setup. In my experience #Percona #Xtrabackup worked best — it can do full backups off of one node super fast and compressed for free. Ideally you’ve got three nodes and take one out from the cluster by setting wsrep thingies to desync it before backup is being performed 👌🏻
