What is Syncoid and Openoid?
Policy-driven snapshot management and replication tools. Currently using ZFS for underlying next-gen storage, with explicit plans to support btrfs when btrfs becomes more reliable. Primarily intended for Linux, but BSD use is supported and reasonably frequently tested. http://www.openoid.net/products/
Syncoid works with OmniOS and could by an alternativ to nappit autosync jobs and rsync.
I prefere nappit driven zfs replication and backup jobs, but syncoid seams be worth the test.
