MariaDB, Galera, xtrabackup - do I need the binary log?
- by bernhardrusch
We are using a MariaDB Galera Cluster with 3 nodes. For the state transfer we are using xtrabackup.
We have some problems with the binary logs - they got too big and crashed the server. We can remove them manually with the purge binary logs command, another way would be to set the expire_logs_days so they would expire.
I now that we could use xtrabackup to backup the DB and use the binlog to get to some point in time. But do we really need it for Galera to work ?
