Description

AMBCT (Automatic Manual Backup Creation Tool) is a command-line based backup utility that uses wimlib-imagex for creating reliable and highly compressed system or file backups.

It combines automation, performance analysis, and manual control to deliver accurate and efficient backup creation — even on legacy systems without modern dependencies.

Core Features

• Native Disk Benchmark System
  → Measures real read/write speed using direct I/O (no OS cache influence)

• CPU Performance Benchmark
  → Determines realistic compression speed

• Dynamic ETA Calculation
  → Based on actual CPU, read, and write speeds
  → Automatically detects bottlenecks

• Accurate Progress Tracking
  → Live progress bar with smoothed ETA

• Full Control Backup System
  → Supports drives, folders, and custom paths

• Offline Capability
  → Works fully without internet connection

Performance System (v1.6+)

AMBCT uses a multi-factor performance model:

• CPU speed (compression)
• Source read speed
• Target write speed

The slowest component determines the effective speed:

This ensures realistic ETA predictions and optimal behavior across all systems.

---

Requirements

• Administrator privileges
• Windows Vista or later
• wimlib-imagex (included)
• No external tools required

Compatibility

AMBCT is designed to work on both modern and legacy systems:

• Windows Vista
• Windows 7
• Windows 8 / 8.1
• Windows 10
• Windows 11

No modern APIs or online services required.

---

Limitations

• VSS only works on NTFS drives
• Performance depends on hardware
• Requires sufficient disk space

---

Known Issues

• ETA may vary under heavy system load
• Antivirus software may slow down operations
• Benchmark may fail on restricted systems (handled safely)

---

Project Status

As of April 2026, AMBCT is still under active development. However, development may be suspended at any time for an indefinite period. Future updates will focus on stability improvements and advanced backup features.
