Specifies the number of replicas each segment file will have. LogScale can handle losing all but one replica before data loss occurs. Segment files stored in bucket storage will not be lost, even if all replicas are lost.

Defaults to 2 if the value is not explicitly set, unless there is only one node in the cluster storing segments, or if USING_EPHEMERAL_DISKS environment variable is set to true. If necessary, a different default can be explicitly set using the DEFAULT_SEGMENT_REPLICATION_FACTOR environment variable.
