[Gluster-users] Understand Geo Replication of a big Gluster

[Kotresh Hiremath Ravishankar]

Hi Axel,

You don't need single server with 140 TB capacity for replication. The
slave (backup) is also a gluster volume similar to master volume.
So create  the slave (backup) gluster volume with 4 or more nodes to meet
the capacity of master and setup geo-rep between these two volumes.
Geo-replication is between two gluster volumes and not between gluster
volume and single node.


Thanks,
Kotresh HR
