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¶

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