When preparing to create a Windows partition image from Linux, we need to consider several technical aspects:

• Filesystem compatibility (NTFS for Windows, EXT4/BTRFS for Linux)
• Block-level vs file-level imaging
• Compression options
• Boot sector preservation

Here are the most reliable utilities for Windows partition imaging under Linux:

1. dd (Disk Dump) - The Classic Approach

For raw sector-by-sector copying:

sudo dd if=/dev/nvme0n1p2 of=~/windows_backup.img bs=4M status=progress

To compress the image during creation:

sudo dd if=/dev/nvme0n1p2 | gzip -c > ~/windows_backup.img.gz

2. Partclone - Filesystem-Aware Imaging

Better for NTFS partitions with sparse file support:

sudo partclone.ntfs -c -s /dev/sda2 -o ~/windows_ntfs_backup.pcl

Restore command:

sudo partclone.ntfs -r -s ~/windows_ntfs_backup.pcl -o /dev/sda2

3. FSArchiver - Advanced Features

Supports multi-volume archives and compression:

sudo fsarchiver savefs ~/windows_backup.fsa /dev/nvme0n1p2 -z 3 -j 4

For those preferring graphical interfaces:

• GNOME Disks: Built-in utility with "Create Disk Image" option
• Clonezilla Live: Bootable environment with advanced options
• GParted: Can create partition images through its UI

Always verify created images:

# For raw dd images
sudo cmp /dev/nvme0n1p2 ~/windows_backup.img

# For partclone
sudo partclone.ntfs -v -s ~/windows_ntfs_backup.pcl

Example cron job for weekly backups:

0 3 * * 0 root /usr/bin/partclone.ntfs -c -s /dev/sda2 -o /backups/windows_$(date +\%Y\%m\%d).pcl && gzip /backups/windows_$(date +\%Y\%m\%d).pcl

As a dual-boot user, I frequently need to create backup images of my Windows partition before making system changes. Unlike Windows-native tools, Linux offers more flexible approaches that work at the filesystem level.

The most universal method using built-in Linux tools:

# Identify your Windows partition
sudo fdisk -l

# Typical output for NTFS partition:
# /dev/nvme0n1p3 104857600 209715199 104857600 50G Microsoft basic data

# Create compressed image (replace X with your actual partition)
sudo dd if=/dev/nvme0n1p3 | gzip > windows_backup.img.gz

# Restore command (WARNING: Destructive operation!)
gunzip -c windows_backup.img.gz | sudo dd of=/dev/nvme0n1p3

For more user-friendly operation with progress tracking:

# Install Clonezilla
sudo apt install clonezilla

# Launch in terminal mode
sudo clonezilla

# Follow menu prompts to:
# 1. Select device-image
# 2. Choose local directory for backup
# 3. Select partition to backup
# 4. Choose compression level

For users preferring graphical interfaces:

• Launch "Disks" from Gnome menu
• Select Windows partition in left panel
• Click gear icon → "Create Disk Image"
• Choose destination (supports .img and compressed .img.gz)

When imaging mounted partitions:

# For NTFS partitions, use ntfsclone for better results
sudo apt install ntfs-3g
sudo ntfsclone --overwrite /dev/sdX windows_ntfs.img

For automated backups, consider this cron job example:

0 3 * * 0 root dd if=/dev/nvme0n1p3 | gzip > /backups/windows_$(date +\%Y\%m\%d).img.gz

Always verify your backups:

# For dd images:
sudo cmp /dev/nvme0n1p3 windows_backup.img

# For Clonezilla images:
sudo clonezilla -v /path/to/image
