It is very flexible, supporting several transports; several job types (push, pull, etc.); several pruning options; separate pruning schedules for sending and receiving sides. It is designed to tolerate downtime on both the sending and receiving side. Underlying synchronisation is via ZFS snapshots and ZFS send/recv. It appears to be under active development. A possible downside is that it might be seen as more involved to set up (due to flexibility), but the documentation is good and examples are provided. Cheers, Paul.
