As you may know I closely follow Galera replication development, and right now I am evaluating how it performs in our benchmarks. Of course my closest interest is Percona Server, so I made port of Galera from MySQL/InnoDB-plugin to Percona Server 5.1.57. Right now it is only in source code https://code.launchpad.net/~vadim-tk/percona-server/percona-galera-5.1.57, but it brings couple good things:
You are welcome to try it, however it is not recommended to use in production, as my port is on very early stage yet.
If it shows good result in evaluation, we are going to provide Percona Server binaries with Galera replication module.
Henrik,
Incremental is not yet supported, it requires support on Galera and InnoDB side, so it may be not so fast implementation.
Does the xtrabackup method also enable me to use incremental backup, or still need to do full backup?
