I installed znapzend on unraid and did the initial configuration. My daemon is running but zfs list -t snapshot shows no datasets available

*** backup plan: citadel ***
         enabled = on
         mbuffer = off
    mbuffer_size = 1G
   post_znap_cmd = off
    pre_znap_cmd = off
       recursive = on
             src = citadel
        src_plan = 7days=>1hour,30days=>4hours,90days=>1day
        tsformat = %Y-%m-%d-%H%M%S
      zend_delay = 0

NOTE: if you have modified your configuration, send a HUP signal
(pkill -HUP znapzend) to your znapzend daemon for it to notice the change.

I created the backup plan like this znapzendzetup create --recursive SRC '7d=>1h,30d=>4h,90d=>1d' citadel

debug shows the below

This is the first time I am using it and I am certain I am doing something wrong. Any help will be appreciated. Thanks

I have a question, i simply want to make a lokal backup of my zfs filesystem. This is the command i got: znapzendzetup create --recursive --tsformat='%Y-%m-%d-%H%M%S' SRC data DST '1y=>1w' HDD

Now i always get the errormessage: zLog must be specified at creation time!

What do i have to do, that it works? What could be my mistake? Thank you in advance for the help

I'm using znapzend to do some backups and unfortunately its flooding my gigE connection. I would like the ability to ratelimit znapsend. Something like:

zfs send | pv -L 200m | ssh $host zfs recv

Any suggestions?
