What the Script Does

1. Instance Name Configuration — You'll specify a unique identifier for your facility (such as lab1 or centerA), which the script processes for system compatibility.

2. Tool Installation — The script verifies and installs rsync if needed.

3. SSH Key Generation — An SSH keypair is created to establish secure, encrypted communication channels with your backup destination.

4. Backup Server Configuration — You'll provide the username and network address (IP or hostname) of your backup server.

5. Connection Testing — The script validates connectivity and requests corrected credentials if the initial connection attempt fails.

6. Key Transfer — Your SSH public key is automatically deployed to the backup server.

7. Backup Script Creation — A dedicated script is generated to synchronize /var/www/vlsm with your backup location.

8. Scheduling — Cron jobs are configured to execute backups every 6 hours and upon system restart.
