I have following gluster volume, details are as follows
Volume Name: geo-vol Type: Distribute Status: Started Number of Bricks: 1 Transport-type: tcp Bricks: Brick1: bst:/backup Options Reconfigured: geo-replication.indexing: on
I am mounting this volume on the same machine as nfs mount and brick1 is also on the same machine and than using geo-replication to mirror it to the backup server.
As you can see from my setup I am using glusterfs for almost realtime backup.
I just need reliable way to backup my data to secondary server, earlier I was using rsync but it started taking a lot of memory as number files increased, so we switched to gluster, when we tried real time replication it was hampering performance of the server, so in the last resort we went with ge-replication, one issue which we are facing right now is the cpu consumption of gluster is way high, I asked this question to gluster mailing list but no update.
