Systemd timer unit (feddit.de)

I try to create a timer unit for weekly and daily backups. For example with the weekly unit, it should be executed once in a week, some minutes after login. If the unit was successful, it should shutdown and not start again until the next week. If a start of this unit was missing, it should be start again some minutes after the next login.

But for some unknown reason, the current unit starts after every login when I reboot the laptop. I am relatively sure that this timer unit is set up wrong, but unfortunately I don't know how I can implement such a unit better with the functions mentioned above.

[Unit]
Description=Run backup weekly
Requires=backup.service

[Timer]
Unit=backup.service
OnCalendar=weekly
RandomizedDelaySec=120
Persistent=true

[Install]
WantedBy=timers.target

OK, many thx for the tips. Since my script in the service file is already doing some logging, i will try to use the last log entry, to find out, when it was last time running and exit the script, if it is not in the timeframe of 1 week.

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.
