3. Read About Cron and Crontab to Automate the Backup Script:

   cron and crontab are components in Linux that allow users to automate tasks, including backup scripts, at scheduled intervals.

   cron: is a time-based job scheduler in Unix-like operating systems. It runs in the background and executes commands or scripts at predefined times without user intervention.

   To access the cron configuration, you can use the following command:

    crontab -e
   

   

   This opens the crontab file for editing. Each line in the crontab file represents a scheduled task. The syntax for a cron job is as follows:

   

   The five asterisks represent the time and date information for scheduling:

   Minute (0 - 59)

   Hour (0 - 23)

   Day of month (1 - 31)

   Month (1 - 12)

   Day of week (0 - 6, where 0 is Sunday)

For example, the following cron job runs a backup script every 2 Minutes:

After saving the crontab file, this backup script will automatically execute at the specified time.

Shows all the cron jobs (scheduled tasks) that are set using the crontab for the current user.
