I also used that site https://crontab.guru/ when creating this cronjob. Your info is ok but in my case the script is in the source directory, so according to what I read and what they told me in another forum the cronjob should look like:
0 1 * * SUN /home/moltke/dir/cp.sh #the * * are wildcards so meaning the job will run every week and every month.
Since the script contains the command which is there's no need to add the command. Regarding rsync I think cp is good enough to do te job. BTW, you're right; instead of SUN one could use 0 or 7. There are another ways to do this it seems according to what I read, like using @weekly instead of the whole "0 1 * * SUN/0/7" but I need to read more about it before using it. For now this is supposed to work.
I guess I'll find out on Monday :
