From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

[Solved] Trouble setting systemd timer (lemmy.dbzer0.com)

I'm trying to move away from cron jobs, not that they don't work, but I want to get on with the times and also learn some things.

I created two user timers (and the associated services), one for backing up my data and the second to upload to B2. I'm using two scripts I had in my cron jobs for a few years and they worked without problems. But with systemd timers both scripts fail with exit code 15 (process terminated) and I have no idea why.

I run Debian 12 Bookworm.

Here's the output for the status of the upload service:

> systemctl --user status rclone-up.service
○ rclone-up.service - Run rclone up for b2
     Loaded: loaded (/home/clmbmb/.config/systemd/user/rclone-up.service; disabled; preset: enabled)

Apr 11 06:12:18 tesla systemd[1698218]: rclone-up.service: Consumed 12.811s CPU time.

Also, here's the log created by rclone while running:

Where should I look to get some more information about what's going on? Why would the service be terminated like that?

LE:

Setting TimeoutSec=infinity inside the [Service] section of the unit file seems to help. Not 100% if it's a good idea, but I'll experiment with it.

Here is my template

sudo cat > /etc/systemd/user/rsync-backup.service < /var/log/rsync-backup.log'
# write errors to log
StandardError=file:/var/log/rsync-backups.log

# GUI message
#ExecStartPost=/usr/bin/notify-send -t 0 -a "Backup" "rsync backup finished." "$(output of some command if you want infos about the backup)"

# run with low priority, when idling
# Nice=15
IOSchedulingClass=idle

# when conditions were not met, try again after 15 minutes
# Restart=on-failure
# RestartSec=900

[Install]
WantedBy=multi-user.target
EOF

Timer file:

sudo cat > /etc/systemd/user/rsync-backup.timer <

I can't see anywhere that a [Timer] section can be added to a service unit. I tried it and it doesn't work:

Apr 11 13:16:15 computer systemd[2593025]: /home/clmbmb/.config/systemd/user/test.service:10: Unknown section 'Timer'. Ignoring.

The service/script ran as it should, but the Timer section is ignored, as you can see.

Okay good notice. You should put that in a deparate .timer file then

Thanks for the suggestion. I'll look into this too.
