echo "=========================================="

echo "=========================================="
echo "Volume Name: $VOLUME_NAME"
echo "Backup Dir : $BACKUP_DIR"
echo "------------------------------------------"

# List available backups
echo "Available Backups:"
ls -1 "$BACKUP_DIR"/*.tar.gz 2>/dev/null
if [ $? -ne 0 ]; then
	echo "❌ No backup files found in $BACKUP_DIR"
	exit 1
fi
echo "------------------------------------------"

# Ask user for backup file to restore
read -p "Enter backup filename to restore (e.g., ad_samba_backup_2026...tar.gz): " BACKUP_FILENAME

FULL_BACKUP_PATH="${BACKUP_DIR}/${BACKUP_FILENAME}"

if [ ! -f "$FULL_BACKUP_PATH" ]; then
	echo "❌ Error: Backup file not found: $FULL_BACKUP_PATH"
	exit 1
fi

echo "⚠️  WARNING: This will OVERWRITE existing data in volume '$VOLUME_NAME'!"
read -p "Are you sure you want to continue? (y/N): " CONFIRM
if [[ ! "$CONFIRM" =~ ^[Yy]$ ]]; then
