crontab：同一脚本仅在一天触发

Question

I'm not a linux expert and need some support to a crontab mystery (for me). I'd like to do a backup of my raspberry pi twice a week. It's the same script. But only the every monday trigger (dow=1) executes. The Friday rule (dow=5) does nothing at all - no backup saved. I can't see why. What's going wrong? Where can I find out what's going wrong?

# Output of the crontab jobs (including errors) is sent through
# email to the user the crontab file belongs to (unless redirected).
#
# For example, you can run a backup of all your user accounts
# at 5 a.m every week with:
# 0 5 * * 1 tar -zcf /var/backups/home.tgz /home/
#
# For more information see the manual pages of crontab(5) and cron(8)
#
# m h  dom mon dow   command
0 4 * * 1 /home/pi/Backup/backup.sh > /dev/null
0 4 * * 5 /home/pi/Baclup/backup.sh > /dev/null

You did everything correctly. You were just missing a second pair of eyes to see that you have a typo in the second line:

Baclup vs Backup
