I don't fully understand your requirements, please clarify. I understand that if you reboot your machine serveral times in a day, the script should only run after first reboot, is that right? If your machine runs for more than 1 day long, should the script be run in consecutive days?

Exactly. I will make a backup every day no matter how often I reboot my PC.

That's right. That's why I'm currently using anacron and the good old at, with a daily job likeecho "obnam backup" | at "now + 10 minutes"

See: /lib/systemd/system/systemd-tmpfiles-clean.timer:
[Timer]
OnBootSec=15min
OnUnitActiveSec=1d
This runs the corresponding .service file 15 minutes after boot and then every day while the system is up. If you reboot multiple times in the same day, you can just have the backup script check the mtime of the archive and skip that run if it's less than a day old.
Also, if your backups are going to be heavy on IO, it might be helpful to read about the IOScheduling* directives in the systemd.exec(5) manpage.

If you're not hung up on 10 min after boot, you can:
[Unit]

[Timer]
OnCalendar=daily
Persistent=true
[Install]
WantedBy=timers.target
OnCalendar=daily makes it run every midnight, Persisten=true on boot if there was at least one missed run.

I don't fully understand your requirements, please clarify. I understand that if you reboot your machine serveral times in a day, the script should only run after first reboot, is that right? If your machine runs for more than 1 day long, should the script be run in consecutive days?
– Krzysztof Adamski

Exactly. I will make a backup every day no matter how often I reboot my PC.
