I would say that trying to change the way a tool works because you want to use the tool incorrectly is not the best approach.
If you want to use a gluster volume to make a backup of a file, and that you want that backup to be on a different server (which is sensible), you should make sure that the original file is not on the same machine as one of the bricks.
Either that, or set up your gluster volume to have replicas.
Cheers,
Kingsley.

We have some data in one disk of node (brick A),and want to put the backup of the data into glusterfs.

Hi,
Can the replica position be configured ?
Could you give an example?
