Image Format

Right now we support 4 different types of images:
  • extdump
  • ntfsdump
  • diskdump
  • custom

extdump & ntfsdump

Those two formats are raw copies (using dd) of partitions hosting Linux systems on ext{2,3,4} and Windows systems on ntfs filesystems respectively.

Partitions hosting a Windows or linux system that are suitable for dumping should have the following properties:
  • Be the first partition in the filesystem
  • The OS they host shall not depend on any other partitions
  • Start at sector 2048
  • Have a bootloader installed in the partition
  • Have the root device named through UUID in /etc/fstab (for extdump only)

Known Issues

  • For linux systems, having grub installed in the partition is fragile and things can go wrong when resizing the partitions, especially when shrinking.
  • Swap space is not supported.
  • More complicated partition schemes are not supported.


Diskdump is a newer format that overcomes most of the aforementioned issues
