I have a three node cluster. Should we be performing XtraDB backups independently on each/all the nodes or designate a specific node ?
Currently all transactions/connections are routed to ONLY node1. I am thinking of offloading the the XtraDB backup to node2 OR node3. But I can see that the binlog files on node1 are bigger in sizes which is as expected. Binlog for the other nodes are minimal. Do you see any issues/gotchas when performing point in time recovery using node2 or node3 full backups and binlog files?
