   cd Bash-script-for-backing-up-file-updates

Scheduling Automated Backups with Cron

To schedule automated backups using cron, you can follow these steps:

1. Open the Crontab Configuration:

   crontab -e

2. Add a Cron Job to Run the Backup Script Every 24 Hours:

   Add the following line to the crontab file, adjusting the paths to your actual script, target directory, and destination directory:

   0 0 * * * /path/to/backup.sh /path/to/target_directory /path/to/destination_directory

   This cron expression runs the backup script every day at midnight (00:00).

3. Save and Exit:

   • For Nano editor, press Ctrl + X to exit, press Y to confirm changes, and then press Enter to save.
   • For other editors, follow the respective instructions to save and exit.

4. Verify Cron Job:

   To verify that your cron job has been added, use the following command:

   crontab -l

   You should see the scheduled cron job in the list.

Now, the backup script will be automatically executed every 24 hours, creating compressed archives for files modified within the last day.

Note: Ensure that the cron service is running. If not, you may need to start it using the appropriate command for your system.
