Log Backup Script

A simple bash script to archive system logs periodically using cronjobs and passwordless sudo for tar.

Features

• Backs up /var/log/*.log files
• Archives backups to ~/log-backups
• Automates using a cronjob
• Uses passwordless sudo for smooth automation

Setup

1. Configure passwordless sudo for /bin/tar
2. Set up a cron job to run the script every minute or change to your preferred time

Important Note: Why Use /bin/tar Directly

In the backup script, sudo /bin/tar is used instead of simply sudo tar.

This is intentional:

• Using /bin/tar ensures that the script calls the exact trusted system binary located at /bin/tar.
• It avoids any security risks where another tar binary (possibly malicious) could be found elsewhere in the system's PATH.
• This ensures the backup is performed securely and reliably.
