I hope your well.
I have a question in regards to xtrabackup and the requires of tables with primary keys, I’m pretty sure I read up that primary keys are required for xtrabackup to function but I can’t remember where that is why I have decided to ask here.
I was looking at xtra dbcluster, but that looks like I would have to build a new cluster all together and then migrate data over which wouldn’t be suitable, but I have been advised that xtrabackup it’s self is a great tool for Galera clusters.
Any advice would be awesome, as I need to look at getting this installed asap. Our cluster is monitored through the cluster control free version.
