Running rclone sync on shutdown

  • 772

I wanted my cloud storage sync to be performed during system shutdown. For this purpose I use rclone with MEGA cloud storage. So, thanks for guide-writers I got the next:

run_on_shutdown.service:

[Unit]
Description=Syncing with MEGA cloud storage
DefaultDependencies=no
Before=shutdown.target halt.target
RequiresMountsFor=/home/yevhenii
After=network-online.target

[Service]
Type=oneshot
User=yevhenii
ExecStart=/home/yevhenii/Projects/ubuntu-scripts/mega_sync_pc.sh

[Install]
WantedBy=halt.target shutdown.target

And simple script that it runs:

REBOOT=$( systemctl list-jobs | egrep -q 'reboot.target.*start' && echo "rebooting" || echo "not_rebooting" )

if [ $REBOOT = "not_rebooting" ]; then

    echo "Syncronizing Projects" >> /home/yevhenii/log.txt
    #rclone check /home/yevhenii/Projects mega:Projects >> /home/yevhenii/log.txt
    rclone sync /home/yevhenii/Projects mega:Projects >> /home/yevhenii/log.txt
    echo "" >> /home/yevhenii/log.txt

    REPORT=$(systemctl status run_on_shutdown)
    echo $REPORT >> /home/yevhenii/log.txt

fi

Result: it doesn't work. this script runs on shutdown, but i don't receive any messages from rclone. It only prints "Syncronizing Projects" in log file. Neither sync, not check - is working. What's wrong with this ? Executing 'rclone check' in command line results in very quick respond (1-2 sec), meanwhile shut downing stretched out up to 10 seconds or even more.

shutdown boot services systemd rclone

  1. I think you need to put an appropriate ExecStop= line and appropriate After= lines in the [Service] section.

    Anyway, I have a similar script. It does not do rsync; but it does other network related things during system START and also during system STOP.

    I am using the following service definition (file: /lib/systemd/system/zzz-my-sss.service)

    [Unit]
Description=Execute system START and STOP script
After=network.target syslog.target
After=systemd-user-sessions.service
After=network-online.target

[Service]
User=_my_user_
Type=oneshot
ExecStart=/home/_my_user_/path/to/my/script.sh START
RemainAfterExit=true
ExecStop=/home/_my_user_/path/to/my/script.sh STOP
StandardOutput=syslog
StandardError=syslog

[Install]
WantedBy=multi-user.target

    Here _my_user_ is my normal Ubuntu user. The script /home/_my_user_/path/to/my/script.sh will be called during system startup (after network is up) with a parameter START. Similarly, it will be called during system shutdown (before network goes down) with a parameter STOP.

    You should enable this service using:

    # systemctl enable zzz-my-sss.service

    You can start / stop it manually using:

    # systemctl start zzz-my-sss.service
# systemctl status zzz-my-sss.service
# systemctl list-units | grep zzz-my-sss.service
# systemctl stop zzz-my-sss.service

    And disable it using:

    # systemctl disable zzz-my-sss.service

    If you update it, do not forget to run:

    # systemctl daemon-reload

  2. After a bunch of attempts I finally got the solution. I couldn't find the way how to make auto-sync.sh run only on shutdown. So, I just found the way to check it with bash.

    Service File

    [Unit]
Description=Syncing with MEGA cloud storage v100
After=network-online.target

[Service]
User=yevhenii
Type=oneshot
ExecStart=/bin/true
ExecStop=/path_to_your_script/auto-sync.sh
RemainAfterExit=true
TimeoutStopSec=0
StandardOutput=tty
StandardError=inherit

[Install]
WantedBy=multi-user.target

    Script file

    REBOT_FACTOR=$( systemctl list-jobs | egrep -q 'reboot.target.*start' && echo "rebooting" || echo "not_rebooting" )

if [[ "$REBOT_FACTOR" == "not_rebooting" ]]; then
    # You can perform your rclone sync right here.
    # Code here will be started only at shutdown.
fi
