Backup a Windows system

1. Create a Fedora LiveCD on USB flash driver
2. Reboot the machine to Fedora
3. Backup partition information

# sfdisk -d /dev/sda | ssh serverip 'cat > /folder/sda.ptb'

4. Backup MBR or MBR+Bootloader

# dd if=/dev/sda bs=512 count=1 | ssh serverip 'cat > /folder/sda.mbr'
# dd if=/dev/sda bs=512 count=63 | ssh serverip 'cat > /folder/sda.vbr'

5. Backup the restore image (count is set to the value from sfdisk output for /dev/sda1)

# dd if=/dev/sda bs=512 skip=63 count=20980827 | ssh serverip 'cat > /folder/sda1.img'

6. Check NTFS system size and if it needs run 'chkdsk /f /r'

# ntfsresize --info /dev/sda2

7. Backup Windows NTFS system

# ntfsclone -s -o - /dev/sda2 | ssh serverip 'cat > /folder/sda2.ntfs.img'

8. Run sha256sum to verify if the hashes match

# dd if=/dev/sda bs=512 skip=63 count=20980827 | sha256sum | ssh 'cat > /tmp/sda.sum'
