title: Crontab does not run on CentOS 7
body: <p>I'm using CentOS 7, and installed "cronie"</p>
  
  <pre><code>yum install cronie
  </code></pre>
  
  <p>I have a shell to backup my home folder, shell's content (of course, backup.sh is 775)</p>
  
  <pre><code>#!/bin/bash
  #START
  TIME=`date +%Y-%m-%d_%Hh%M`          
  FILENAME=backupHome_123.30.150.29_$TIME.tar.gz 
  SRCDIR=/home                    
  DESDIR=/backup            
  tar -cpvzf $DESDIR/$FILENAME $SRCDIR
  #END
  </code></pre>
  
  <p>And add to crontab -e</p>
  
  <pre><code>00 2 * * * /bin/bash /backup/backup.sh
  </code></pre>
  
  <p>But crontab does nothing. When I check log at /var/log/cron only, something like that and no more error or processing log</p>
  
  <pre><code>May  1 00:26:08 app crontab[12041]: (root) END EDIT (root)
  May  1 00:33:21 app crontab[12086]: (root) BEGIN EDIT (root)
  May  1 00:34:25 app crontab[12086]: (root) END EDIT (root)
  </code></pre>
  
  <p>Anyone can give me some advises to make crontab work?
  Thank you.</p>
