Smart System Exclusions (File Mode)

When backing up an entire drive (e.g., D:\), Nimbus Backup automatically excludes:

System Folders:

• System Volume Information - VSS snapshots storage (can be 100+ GB)
• $RECYCLE.BIN - Windows recycle bin
• Recovery - Windows recovery partition data

System Files:

• pagefile.sys - Windows page file
• hiberfil.sys - Hibernation file
• swapfile.sys - Windows swap file

Why this matters:

• Drive shows 1.03 TB used but actual files are 141 GB
• Without exclusions, backup would include VSS snapshots (wasted space + time)
• With exclusions, backup size matches real data (~141 GB)

Recommendation:

• File-level backups (default): Use file mode with auto-exclusions
• Bare-metal restore: Use disk mode in separate job (includes everything)

🚀 Quick Start

1. Download NimbusBackup.exe from releases
2. Run with administrator privileges (required for VSS)
3. Configure your PBS connection
4. Test connection
5. Select directories to backup
6. Start backup

📋 Requirements

• Windows 10/11 (64-bit)
• Administrator rights (for VSS snapshots)
• Network access to PBS server
