My daily backup crashed, how can I rerun cron daily?

My daily backup crashed because a "bad" file of 30 MB existed which caused me to exceed by 25 MB daily backup limit:

-rw-rw-r-- rick/rick  29018177 2021-08-09 23:07 .config/mserve/ipc.pickle

I've removed the file but how can I call tell cron to run /etc/cron.daily jobs again?

Solution 1:

This answer is close but you really want to use:

sudo run-parts /etc/cron.daily

The linked answer omits sudo and my daily backup crashed again. This is because the same .tar work file (with errant 30 MB file) that was created with sudo privileges (which cron runs with) still existed.

I had removed the "bad" 30 MB file but the earlier .tar file created by the original cron job was still about. My regular user privileges simply were insufficient to recreate a new .tar file.

If you call run-parts without sudo your environment is different. Using sudo for run-parts makes it work. In my case at least.
