I have a script called backup.sh:

sudo zip -r /home/jazuly/backup.zip /var/lib/automysqlbackup/
cd /home/jazuly/backupscript/cp2google/
php cp2google.php /home/jazuly/backup.zip
cd ~
rm -f /home/jazuly/backup.zip

I made it executable:

sudo chmod +x backup.sh

Then I tried to edit cronwith crontab -e.

I add:

# m h dom mon dow command
0 0 * * * /home/jazuly/backup.sh

but when cron sends the backup.zip to my email, I download and open it, and the file is corrupt.

If I run the script manually with:

$ sudo chmod +x backup.sh 
$ ./backup.sh

I can open the zip file.

  • what message you get when fie corrupted ?

    Are you sure the script works? You create /home/jazuly/backup.zip as root (sudo) and then try to delete it as a regular user (rm -f /home/jazuly/backup.zip), that doesn't make sense.

You will need to use the full path in any cron executed script. So, don't do cd ~, give instead cd /home/jazuly

For further debugging, you can also redirect the output of the cron script to a file, with /home/jazuly/backup.sh 1> /home/jazuly/log.txt 2> /home/jazuly/err.txt

So the whole command:

# m h dom mon dow command
0 0 * * * /bin/bash /home/jazuly/backup.sh 1> /home/jazuly/log.txt 2> /home/jazuly/err.txt
  • i try it but crone not send me anything. im already delete that path change with rm -f /home/jazuly/backup.zip

  • Just updated the answer about the path - don't use relative paths, try cd /home/jazuly in your script

  • Also the php line, use the full path there too.

    The extensions are irrelevant. The point you make in the comments about using the absolute path is helpful, but your answer is just wrong: cron doesn't care about extensions at all.

Try to use full paths

/usr/bin/zip -r /home/jazuly/backup.zip /var/lib/automysqlbackup/
/usr/bin/php /home/jazuly/backupscript/cp2google/cp2google.php /home/jazuly/backup.zip
rm -f /home/jazuly/backup.zip

And add /bin/bash in cron

# m h dom mon dow command
0 0 * * * /bin/bash /home/jazuly/backup.sh

And check permissions for files backup.zip, backupdatabaseterbaru-c771cd4f4fcf.p12

  • Run chown jazuly.jazuly file_name or chown -R jazuly.jazuly directory for all files and directories with owner root.

Here are the steps of how I fixed it:

  1. Change Permission & Owner of var/lib/automysqlbackup to 777 & jazuly.jazuly.
  2. Move all the folders & files from backupscript/cp2google/ to home/jazuly.
  3. Use wait for every statement.
  4. My final code:

    zip -r backup.zip /var/lib/automysqlbackup/
    php cp2google.php backup.zip
    rm -f backup.zip

    And my cron:

    0 0 * * * /home/jazuly/backup.sh

    to backup every midnight/day.

    I don't think there is a need to write the full path if the .sh file is in the same path with what you want to execute.
