[OmniOS-discuss] zfs send | recv

[Oliver Weinmann]

Yes it is recursively. We have hundreds of child datasets so single filesystems would be a real headache to maintain. :(

did you replicate recursively?
keeping a different snap history should be possible when you send single filesystems.

Hi,


We are replicating snapshots from a Nexenta system to an OmniOS system. Nexenta calls this feature autosync. While they say it is only 100% supported between nexenta systems, we managed to get it working with OmniOS too. It's Not rocket science. But there is one big problem. In the autosync job on the Nexenta system one can specify how many snaps to keep local on the nexenta and how many to keep on the target system. Somehow we always have the same amount of snaps on both systems. Autosync always cleans all snaps on the dest that don't exist on the source. I contacted nexenta support and they told me that this is due to different versions of zfs send and zfs recv. There should be a -K  flag, that instructs the destination to not destroy snapshots that don't exist on the source. Is such a flag available in OmniOS? I assume the flag is set on the sending side so that the receiving side has to understand it.



Best Regards,

Oliver
