Hi,

 

I want my system to pause on shutdown to wait till my backup has finished if it is running.

For this I've created this small service:

 

[Unit]
Description=borg shutdown wait

[Service]
Type=oneshot
ExecStart=/bin/true
RemainAfterExit=true

ExecStop=/usr/local/bin/wait_borg
TimeoutStopSec=600

[Install]
WantedBy=multi-user.target

 

I'm using ubuntu 18.04, systemd 237

 

Manually stopping the service via

systemctl stop borg_wrapper

does wait and thus works.

 

But its not working on normal shutdown/poweroff ...

From the logs I can't even see an entry with

"Stopping borg shutdown wait" in syslog.

 

Does anyone has an idea?

I had to achieve something similar a while back and this is how I ended up doing:

Hope it helps.

 

Regards,

Ralf
