I suppose you can either keep the last snaps identical on source and
target with a simple zfs send recursively or <br>
you need a script that cares about and does a send per filesystem to
allow a different number of snaps on the target system.<br>
<br>
This is not related to Nexenta but I saw the same on current OmniOS
-> OmniOS as they use the same Open-ZFS base Illumos<br>

<p class="MsoNormal">Hi,</p>
<p class="MsoNormal"> </p>
<p class="MsoPlainText">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.</p>
