cron 2

Savanna is a RHEL Syadmin at IBM. Her supervisor tell her the write a script to backup /home/savanna/vital_docs to /home/savanna/backup.tar.gz each Sunday at 2:30 AM. Show all the commands that she will issue and the text of the script.

• Create a new directory called backup in /home/savanna.
  • mkdir /home/savanna/backup
• Change the ownership and permissions of the backup directory to ensure that Savanna has write access.
  • chown savanna:savanna /home/savanna/backup
  • chmod 700 /home/savanna/backup
• Create a new script file called backup_script.sh in /home/savanna and add the following code:
  • #!/bin/bash
    
    # Move to the backup directory
    cd /home/savanna/backup
    
    # Create a tar archive of the vital_docs directory
    tar -czf backup.tar.gz /home/savanna/vital_docs
    
    # Move the backup file to the home directory
    mv backup.tar.gz /home/savanna/
• This script changes to the backup directory, creates a compressed tar archive of the vital_docs directory, and then moves the resulting backup file to the home directory.
• Make the script executable.
  • chmod +x /home/savanna/backup_script.sh
• Set up a new cron job to run the script each Sunday at 2:30 AM. To do this, run the following command:
  • crontab -e
• Add the following line to the end of the crontab file:
  • 30 2 * * 0 /home/savanna/backup_script.sh
  • This cron job will run the backup_script.sh file every Sunday at 2:30 AM.
• Overall, the commands that Savanna will need to issue are:
  • mkdir /home/savanna/backup
  • chown savanna:savanna /home/savanna/backup
  • chmod 700 /home/savanna/backup
  • nano /home/savanna/backup_script.sh
  • chmod +x /home/savanna/backup_script.sh
  • crontab -e
• And the text of the script is:
  • #!/bin/bash
    
    # Move to the backup directory
    cd /home/savanna/backup
    
    # Create a tar archive of the vital_docs directory
    tar -czf backup.tar.gz /home/savanna/vital_docs
    
    # Move the backup file to the home directory
    mv backup.tar.gz /home/savanna/
