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

     Loaded: loaded (/home/clmbmb/.config/systemd/user/rclone-up.service; disabled; preset: enabled)

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.
