There is a known behavior of anacron not to run when the laptop is running on batteries. Is there any way to stop this behavior and run anacron whatever the power state?

Please never change any files in /usr! Instead, you may change a line in the file /etc/default/anacron to

ANACRON_RUN_ON_BATTERY_POWER=yes

Thanks @Teresa e Junior. :)

For Debian based systems using systemd look at /usr/share/doc/anacron/README.Debian for instructions on creating /etc/systemd/system/anacron.service.d/on-ac.conf. The README tells what contents the file should be created with. This worked for me running daily snapshots with rsnapshot. I Have only tried this on Ubuntu 20.04. It seems likely that other distros may have a similar README in that directory. /etc/default/anacron has instructions to look in /usr/share/doc/anacron/README.Debian in Ubuntu 20.04. Thanks so much @mzuther : )

Just in case the README is not on someone's system the file contents should be:

I found how to do this and summarized it in my blogpost

http://opensourceresearchtips.blogspot.com/2012/01/linux-anacron-tips.html

To change this behavior of anacron do the following:

 sudo gedit /usr/lib/pm-utils/power.d/anacron

and change to

case $1 in
    false)
 start -q anacron || :
 ;;
    true)
 start -q anacron || :
 ;;
esac
