✨ Features

🗄️ Full Stack Backup: Backs up website directories (/var/www/html) and auto-detects MySQL, MariaDB, and PostgreSQL databases.
🚀 Resume-Supported Transfers: Built on top of rsync over SSH (--partial --inplace) — if network drops, it resumes exactly where it stopped.
🔒 Integrity Verification: Automatically calculates and exports SHA256 checksums for every backup archive.
🔄 Direct Server-to-Server Migration: Push files directly from Source VPS to Destination VPS without downloading them to your home PC.
⏰ Automated Crontab with Auto-Prune: One-click setup for nightly backups with a built-in 7-day retention cleaner to prevent disk overflow.

🛠️ Step-by-Step Usage Guides

Scenario A: Moving to a New VPS (Site Migration)

When migrating from an old host to a faster VPS (e.g., from an entry-level instance to a high-speed CN2 GIA Optimized VPS):

Run ./backup-sync.sh on your Source Server.
Select option 2 (Live Server-to-Server Migration).
Enter the Target VPS IP, SSH Port, and path.
The script transfers all files with maximum bandwidth efficiency.

💡 Tip: Test your network latency before migrating with our free Global Speed & Latency Test Tool.

Scenario B: Automated Nightly Backups

Select option 4 (Configure Automated Daily Backup).
The script configures a silent background cron task running every morning at 03:30 AM.
Backups older than 7 days are automatically removed to protect your disk capacity.
