Improve One-Click Backup verification with multi-method approach
- Implement timestamp-based filename verification (Method 1) - Add file size validation with 1KB minimum requirement (Method 2) - Filter to only check today's backup directory for accuracy (Method 3) - Add optional SHA256 checksum verification for integrity (Method 5) - Use find command with size filter for efficient SSH verification - Fallback to SFTP with comprehensive file validation - Enhanced logging for all verification steps and failures - Remove unused 'Yesterday' variable that was never used - Prevents false positives from old backup files - Detects corrupted/incomplete backups via size check
