I have a remote VM that I am using to keep my encrypted ZFS backups. Also, in my current set-up I have some databases that I need to lock/flush before snapshoting them, and also unlock them when done. Then I have writen a script to lock/unlock the DBs, and another to start/stop the VM, so that my znapzendzetup create looks like (ZFSfiler is the SSH host configuration name in .ssh/config):

znapzendzetup create --recursive \
--pre-snap-command="/bin/bash /home/testuser/lock_DBs_for_snapshot.sh start" \
--post-snap-command="/bin/bash /home/testuser/lock_DBs_for_snapshot.sh stop" \
SRC '1d=>1h,7d=>1d,1m=>1w' zfsdata/tothrow \
DST '1d=>1h,7d=>1d,1m=>1w' ZFSfiler:zfsbackup/tothrow \
"/usr/bin/python3 /home/testuser/manageVM.py start" \
"/usr/bin/python3 /home/testuser/manageVM.py stop"

When running the previous command, I get:

Do you want to save this backup set [y/N]? y
ssh: connect to host zfsfiler.westeurope.cloudapp.azure.com port 22: Network is unreachable
NOTE: if you have modified your configuration, send a HUP signal
(pkill -HUP znapzend) to your znapzend daemon for it to notice the change.

So, the machine is obviously not up as (I think) the manageVM.py script has not been run. Have I hit a bug, or am I doing something wrong (and I do not see what)?
